Connector structure of stepless capacity control actuator of reciprocating compressor

A connector structure of a stepless capacity control actuator for a reciprocating compressor, comprising:

• an ejector rod having a first end configured to connect with an ejector plate of an unloader, and a second end configured to connect with a driving end of a driving structure comprised in the stepless capacity control actuator;
• a housing sleeving the ejector rod, wherein a gap is formed between the housing and the ejector rod, a first oil hole is formed in the housing, two ends of the first oil hole are located on an inner side surface and an outer side surface of the housing, respectively, and a first end of the housing is configured to connect with a valve cover comprised in the reciprocating compressor;
• a connecting member comprising a flange part and a sleeve part, the flange part having a first side configured to connect with a second end of the housing, and a second side configured to connect with a shell of the driving structure and be in sealing contact with the shell, the sleeve part being located between the ejector rod and the housing and being connected to one side, away from the driving structure, of the flange part, wherein a gap is formed between the sleeve part and the ejector rod, a second oil hole is formed in the sleeve part, two ends of the second oil hole are located on an inner side surface and an outer side surface of the sleeve part, respectively, and the second oil hole is in butt joint with the first oil hole;
• and
• a sealing assembly comprising:
• a first end face sealing ring configured to seal a gap between the first side of the flange part and the housing, a second end face sealing ring configured to seal a gap between the valve cover and the housing, a first seal ring located between the ejector rod and the housing, and located on one side, away from the driving structure, of the sleeve part and an oil leakage joint in communication with the first oil hole, wherein an inner side surface of the first seal ring is in sealing contact with the ejector rod, and an outer side surface of the first seal ring is in sealing contact with the inner side surface of the housing to seal the gap between the ejector rod and the housing.
