초록 ▼

A rotary compressor including a housing that defines an inlet, a low pressure chamber, an outlet, and a high pressure chamber defining a high pressure lubricant sump. A drive shaft passes through the housing and a compression element is coupled to the drive shaft between the low pressure chamber and the high pressure chamber. A first path connects the high pressure lubricant sump to the low pressure chamber such that lubricant flows through the first path from the high pressure lubricant sump to the low pressure chamber. A low pressure lubricant sump is positioned within the low pressure chamber and includes a movable gate movable from a closed position to an open position in response to a hydrostatic pressure of the lubricant within the low pressure lubricant sump. A second path connects a lubricant separator and the low pressure lubricant sump.

대표청구항 ▼

1. A rotary compressor comprising: a housing defining an inlet in communication with a low pressure chamber and an outlet in communication with a high pressure chamber defining a high pressure lubricant sump;a drive shaft at least partially passing through the housing;a compression element coupled to the drive shaft and in fluid communication between the low pressure chamber and the high pressure chamber, the compression element compressing a working fluid;a lubricant separator in fluid communication between the high pressure chamber and the outlet to separate lubricant from the working fluid;a first path connecting the high pressure lubricant sump to the low pressure chamber such that lubricant flows through the first path from the high pressure lubricant sump to the low pressure chamber;an internal reservoir positioned within the low pressure chamber and including a movable gate, the movable gate being configured to open from a closed position to an open position in response to a hydrostatic pressure of the lubricant within the internal reservoir reaching a threshold hydrostatic pressure thereby allowing lubricant to exit the internal reservoir; anda second path connecting the lubricant separator and the internal reservoir. 2. The rotary compressor of claim 1, wherein the lubricant separator includes a separator inlet for receiving working fluid and lubricant, a conical portion for separating the lubricant from the working fluid, a separator outlet for expelling working fluid, and a separator drain for expelling lubricant. 3. The rotary compressor of claim 1, wherein the lubricant separator is a cyclonic separator. 4. The rotary compressor of claim 1, further comprising a second lubricant separator positioned in the high pressure chamber to separate lubricant from working fluid such that lubricant collects in the high pressure sump. 5. The rotary compressor of claim 1, wherein the internal reservoir collects lubricant separated by the lubricant separator and a hydrostatic pressure increases as lubricant collects, the movable gate opens at a predetermined hydrostatic pressure. 6. The rotary compressor of claim 1, wherein the housing defines a collecting portion for collecting lubricant in the low pressure chamber and the internal reservoir is positioned above the collecting portion. 7. The rotary compressor of claim 1, wherein the compression element includes a first scroll driven by the drive shaft and a stationary second scroll coupled to the housing. 8. The rotary compressor of claim 1, wherein the lubricant separator is positioned adjacent to the outlet within the high pressure chamber.
