Compressor apparatus for household cooling equipment e.g. refrigerator, freezer has linear drive having adjustable rotor zero position, and linear compressor having adjustable piston zero position

摘要

A linear drive (2) includes a stator (4), and a rotor (5) that is movable along a drive axis (9) between two rotor points (11,12) around a rotor zero position (13). A linear compressor (3) has a piston housing (7) accommodating a compressor piston (6) propellable by the linear drive along a piston axis (8) between two piston points (21,22) around a piston zero position (23). The rotor zero position and piston zero position are adjustable. An independent claim is included for a method of cooling goods.
