A substantially planar suspension spring for supporting a linear compressor housed within a hermetic shell. A hub portion () connects to the body of the compressor assembly while a spiral arm portion () curves around the hub portion () at least one full turn before attaching to the wall of the compressor housing. Provides lateral stability to the reciprocating compressor assembly while maintaining axial flexibility.

Suspension spring for linear compressor

A linear compressor includes a cylinder part with a cylinder bore. A piston is disposed in the bore and slidable therein. A main spring connects the cylinder part to the piston. A connecting member connects between the main spring and the piston. The connecting member passes through the air gap of a stator of a linear electric motor. At least one armature pole of the motor is located along the connecting member. The stator comprises a plurality stator parts opposed across the air gap. The cylinder part includes a tapered clamp for each stator part. The tapered clamp widens outward from the air gap. Each stator part has a matching taper and is engaged in the tapered clamp.

Linear compressor

A linear compressor has a hollow piston with crown and sidewall. The piston reciprocates in a cylinder. A piston rod connects the piston to a spring. A connection between the piston rod and the piston transmits axial forces directly to the piston crown. The connection transmits lateral forces to the piston at an axial location away from the piston crown. The connection allows rotational flexibility between the piston and the piston rod transverse to and uniformly around the piston reciprocation axis. Other improvements in or relating to linear compressors are disclosed.
