Abstract
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.
