Linear compressor for cooling equipment e.g. refrigerator, freezer has linkage having spring, and which couples compressor piston to drive

摘要

A piston housing (2) accommodates a compressor piston (4) movable back and forth along an axis (3). The compressor piston is coupled by a linkage (5) to a drive (6) for moving the compressor piston back and forth. The linkage includes a spring (7), particularly a coil spring. An independent claim is included for a method for cooling or freezing a commodity using a cooling equipment.
