A compressor system with a continuously variable oil injection orifice is structured to regulate a flow of oil from an oil reservoir into a compressor. The orifice includes a first valve member moveable in response to oil pressure toward a second valve member to define a continuously variable flow area. A biasing member urges the first valve member away from the second valve member.

1. A compressor system, comprising: a compressor;an oil reservoir; anda continuously variable oil injection orifice structured to regulate a flow of oil from the oil reservoir into the compressor, the continuously variable oil injection orifice comprising:a first valve member structured to displace
1. A compressor system, comprising: a compressor;an oil reservoir; anda continuously variable oil injection orifice structured to regulate a flow of oil from the oil reservoir into the compressor, the continuously variable oil injection orifice comprising:a first valve member structured to displace in response to oil pressure;a second valve member structured to cooperate with the first valve member to define a continuously variable flow area for controlling a flow of oil through the continuously variable injection orifice;a biasing member structured to urge the first valve member away from the second valve member;wherein oil pressure acting on the first valve member urges the first valve member to move toward the second valve member; andwherein the biasing member is a dual acting spring system with different spring rates. 2. The compressor system of claim 1, wherein a displacement of the first valve member toward the second valve member reduces the continuously variable flow area. 3. The compressor system of claim 1, wherein the second valve member includes a plate having an oil discharge opening for discharging the oil to the compressor. 4. The compressor system of claim 3, wherein the plate includes a mesh disposed in the oil discharge opening. 5. The compressor system of claim 3, wherein the plate includes: a hub having a pilot opening formed therethrough;an outer rim positioned about the hub; andat least one supporting arm extending between the hub and the rim. 6. The compressor system of claim 5, wherein the pilot opening is structured to slidably receive a rod. 7. The compressor system of claim 1, wherein the first valve member includes a head acted upon by oil pressure. 8. The compressor system of claim 7, wherein the first valve member is displaced relative to the second valve member as a function of a change in oil pressure acting on the head. 9. The compressor system of claim 7, wherein the second valve member includes a port, and wherein the continuously variable flow area is defined between the head and the port. 10. The compressor system of claim 7, further comprising a rod extending from the head and slidably coupled with the second valve member. 11. A compressor system, comprising: a screw compressor;an oil reservoir; anda pressure actuated variable oil injection orifice structured to regulate a flow of oil from the oil reservoir into the screw compressor, the pressure actuated variable oil injection orifice including a first valve member; a second valve member and a biasing member, wherein the first valve member is slidably engaged with the second valve member and biased relative to the second valve member by the biasing member; wherein the first valve member, the second valve member and the biasing member cooperate to define a continuously variable flow area that decreases with increasing oil pressure; andwherein the first valve member includes a rod extending from the head configured to slidably engage with the second valve member and the second valve member includes a plate having a pilot opening structured to slidably receive the rod. 12. The compressor system of claim 11, wherein the biasing member is structured to have a first spring rate at a first deflection and a second spring rate at a second deflection, wherein the second spring rate is different than the first spring rate. 13. The compressor system of claim 11, wherein the first valve member includes a head acted upon by oil pressure to displace the first valve member relative to the second valve member. 14. The compressor system of claim 13, wherein the second valve member includes a port, and wherein the continuously variable flow area is defined between the head and the port. 15. The compressor system of claim 11, wherein the plate includes at least one oil discharge opening for discharging oil to the screw compressor. 16. A compressor system, comprising: a compressor;an oil reservoir; andmeans for continuously varying a flow area for controlling a flow of oil from the oil reservoir to the compressor, such that the flow area is reduced as oil pressure is increased up to a predefined limit position; andwherein the means includes a plate comprising: a hub with a pilot opening formed therethrough;an outer rim positioned radially outward of the hub; andat least one supporting arm extending between the hub and the rim. 17. The compressor system of claim 16, wherein the means includes a valve biased to an open position. 18. The compressor system of claim 16, wherein the means includes a valve head configured to urge the valve toward a closed position when a flow of oil passes through the valve. 19. The compressor system of claim 16, wherein the plate includes an opening formed between the hub and the outer rim for discharging the oil to the compressor. 20. The compressor system of claim 19, wherein the opening includes a mesh disposed therein. 21. A compressor system, comprising: a compressor;an oil reservoir; anda continuously variable oil injection orifice structured to regulate a flow of oil from the oil reservoir into the compressor, the continuously variable oil injection orifice comprising:a first valve member structured to displace in response to oil pressure;a second valve member structured to cooperate with the first valve member to define a continuously variable flow area for controlling a flow of oil through the continuously variable injection orifice;a biasing member structured to urge the first valve member away from the second valve member;wherein oil pressure acting on the first valve member urges the first valve member to move toward the second valve member;wherein the second valve member includes a plate having an oil discharge opening for discharging the oil to the compressor; andwherein the plate includes a mesh disposed in the oil discharge opening.
