A compressor assembly having a housing in which a compressor mechanism and discharge chamber are located. A first port communicates compressed gas and oil from the compressor mechanism to the discharge chamber. A one-way valve allows the compressed gas and oil to enter the discharge chamber through the first port. A second port in the discharge chamber defines an outlet in the housing through which compressed gas and oil are discharged from the compressor assembly. The second port is disposed vertically below the first port in the lower half of the discharge chamber to thereby limit the quantity of oil which may collect in the discharge chamber. The second port may be defined by a discharge tube which passes through the housing at a flat portion of the housing which thereby facilitates the welding of the tube to the housing.

What is claimed is: 1. A compressor assembly for compressing a gas and lubricated with an oil, said compressor assembly comprising: a housing having an inlet; a horizontal scroll compressor mechanism disposed within said housing, wherein said compressor mechanism comprises a generally horizontal crankshaft, a fixed scroll member and an orbiting scroll member, said fixed and orbiting scroll members being mutually engaged, wherein said fixed scroll member is sealed against said housing to define a suction chamber and a discharge chamber, said compressor mechanism having an inlet in direct fluid communication with said suction chamber, wherein said suction chamber is in fluid communication with said housing inlet, and wherein said compressor mechanism defines a working space in which gas is compressed, said compressor mechanism having a first port in communication with said discharge chamber whereby oil and compressed gas are communicated from said working space to said discharge chamber; and a second port in said discharge chamber defining an outlet in said housing through which oil and compressed gas are discharged from said compressor assembly, said second port disposed vertically below said first port in a lower half of said discharge chamber whereby oil collected within said discharge chamber is dischargeable with the compressed gas through said second port and wherein substantially all fluids entering said discharge chamber enter through said first port and substantially all fluids exiting said discharge chamber exit through said second port. 2. The compressor assembly of claim 1 further comprising a valve sealingly engageable with said first port, said valve allowing fluids to enter said discharge chamber from said working space and inhibiting passage of fluids from said discharge chamber to said working space. 3. The compressor assembly of claim 1 further comprising a discharge tube, said discharge tube having an inlet positioned in said discharge chamber, said inlet defining said second port. 4. The compressor assembly of claim 3, wherein said discharge tube extends through said housing and said housing includes a relatively flat portion adjacent said discharge tube, said discharge tube being welded to said housing at said flat portion. 5. The compressor assembly of claim 1 wherein said first port is located in said fixed scroll member. 6. A horizontal compressor assembly for compressing a gas and lubricated with an oil, said compressor assembly comprising: a hermetically sealed housing defining a high pressure discharge chamber and a low pressure chamber, said housing further defining an inlet opening in fluid communication with said low pressure chamber, wherein the bottom portion of said low pressure chamber comprises a first oil reservoir and the bottom portion of said high pressure chamber comprises a second oil reservoir, and wherein said first oil reservoir is partitioned from said second oil reservoir; a compressor mechanism disposed within said housing, said compressor mechanism operably disposed between said high pressure discharge chamber and said low pressure chamber and defining a working space in which gas is compressed, said compressor mechanism having a generally horizontally oriented crankshaft, said compressor mechanism having an inlet in direct fluid communication with said low pressure chamber and said working space; a motor for driving said compressor mechanism, said motor located in said low pressure chamber; a first port in communication with said working space and said high pressure chamber wherein compressed gas and oil are communicated from said working space to said high pressure chamber; a second port defining an outlet in said housing and in communication with said high pressure chamber, said second port disposed vertically below said first port wherein a majority of said high pressure chamber is disposed vertically above said second port and wherein substantially all fluids entering said discharge chamber enter through said first port and substantially all fluids exiting said discharge chamber exit through said second port. 7. The compressor assembly of claim 6 further comprising a discharge tube, said discharge tube having an inlet positioned in said high pressure chamber, said inlet defining said second port. 8. The compressor assembly of claim 7, wherein said discharge tube extends through said housing and said housing includes a relatively flat portion adjacent said discharge tube, said discharge tube being welded to said housing at said flat portion. 9. The compressor assembly of claim 6 wherein said compressor mechanism comprises a fixed scroll member and an orbiting scroll member, said fixed and orbiting scroll members being mutually engaged, said first port defined by said fixed scroll member. 10. The compressor assembly of claim 9 further comprising a valve sealingly engageable with said first port, said valve allowing fluids to enter said high pressure chamber and inhibiting passage of fluids from said high pressure chamber through said first port. 11. A method of controlling the movement and accumulation of oil in a horizontal compressor, said method comprising: providing a hermetically sealed housing defining a high pressure chamber and a low pressure chamber, said housing having an inlet; providing a compressor mechanism within said housing, said compressor mechanism having an inlet; placing said housing inlet and said compressor mechanism inlet in direct fluid communication with said low pressure chamber; compressing a gas with said compressor mechanism and discharging oil and compressed gas from said compressor mechanism into said high pressure chamber through a first port; accumulating oil in a bottom portion of said low pressure chamber; accumulating oil in a bottom portion of said high pressure chamber; partitioning the oil in the bottom of said low pressure chamber from the oil in the bottom of said high pressure chamber; positioning a second port in said high pressure chamber vertically between said bottom portion and said first port; limiting the accumulation of oil within said high pressure chamber by discharging excess oil through said second port together with compressed gas; and enclosing said high pressure chamber wherein substantially all fluids entering and discharged from said high pressure chamber enter and exit said high pressure chamber through said first and second ports. 12. The method of claim 11 further comprising the step of providing a motor for driving said compressor mechanism and disposing said motor in said low pressure chamber. 13. The method of claim 12 further comprising the step of circulating oil within said low pressure chamber. 14. The method of claim 11 wherein said compressor mechanism comprises a fixed scroll member and an orbiting scroll member and said step of compressing a gas with said compressor mechanism includes orbiting said orbiting scroll member relative to said fixed scroll member. 15. A compressor assembly comprising: a housing having a low pressure chamber and a high pressure chamber; a compressor mechanism, wherein said compressor mechanism has an inlet in direct fluid communication with said low pressure chamber and an outlet in fluid communication with said high pressure chamber; a first oil reservoir in said low pressure chamber; a second oil reservoir in said high pressure chamber, wherein said first oil reservoir is partitioned from said second oil reservoir; a suction inlet in said housing, wherein said housing inlet is in fluid communication with said low pressure chamber; and a discharge outlet in said housing, wherein said discharge outlet is in fluid communication with said high pressure chamber, and wherein said housing outlet is positioned vertically below said compressor mechanism outlet, whereby oil in said second reservoir exits said high pressure chamber though said housing outlet. 16. The compressor assembly of claim 15 wherein said compressor mechanism is sealed against said housing to partition said first oil reservoir from said second reservoir.
