LINEAR COMPRESSOR

摘要

A linear compressor is provided. The linear compressor includes a piston slidably received within a chamber of a cylinder assembly and a mover positioned in a driving coil. The linear compressor also includes features for coupling the piston to the mover such that motion of the mover is transferred to the piston during operation of the driving coil and for reducing friction between the piston and the cylinder during motion of the piston within the chamber of the cylinder.

主权项

1. A linear compressor defining a radial direction, a circumferential direction and an axial direction, the linear compressor comprising:
a cylinder assembly defining a chamber; a piston received within the chamber of the cylinder assembly such that the piston is slidable along a first axis within the chamber of the cylinder assembly; an inner back iron assembly; a driving coil extending about the inner iron assembly along the circumferential direction, the driving coil operable to move the inner back iron assembly along a second axis, the first and second axes being substantially parallel to the axial direction; a magnet mounted to the inner back iron assembly such that the magnet is spaced apart from the driving coil by an air gap along the radial direction; and a flexible coupling comprising
a flat wire coil spring extending between the inner back iron assembly and the piston along the axial direction; anda wire disposed within the flat wire coil spring and extending between the inner back iron assembly and the piston along the axial direction.
