COMPRESSOR IMPROVEMENTS

摘要

A linear compressor has a hollow piston (8002) with crown (8009) and sidewall (8006) reciprocating in a cylinder with a piston rod (8000) connecting the piston (8002) to a spring. A axially stiff but laterally compliant connection (8001) between the piston rod (8000) and the piston (8002) transmits axial forces directly to the piston crown (8009) while transmitting lateral forces to the piston (8002) at axial location away from the piston crown (8009). The connection (8001) allows rotational flexibility between the piston (8002) and the piston rod (8000) transverse to and uniformly around the piston reciprocation axis.
