Swing Motor Mechanism

The swing motor mechanism directly conveys thrust force to pistons to compress and pump air. Unlike general reciprocating compressors that require rotation-to-linear motion conversion, this swing motor design eliminates intermediate systems, resulting in significantly reduced transmission power loss and improved operational efficiency.
