Abstract
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.
Claims25
A compressor system, comprising:
- a compressor;
- an oil reservoir;
- and
- a 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;
- and
- wherein oil pressure acting on the first valve member urges the valve member to move toward the second valve member.
6 more elements
A compressor system, comprising:
- a screw compressor;
- an oil reservoir;
- and
- a 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;
- and 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.
3 more elements
A compressor system, comprising:
- a compressor;
- an oil reservoir;
- and
- means 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.
