摘要： A linear compressor(300) or sealed system may include a casing(308), a piston(316), an driving coil(366), an inner back iron assembly(352), and a planar spring assembly (500). The casing(308) may include a cylinder assembly (310)defining a chamber(312) along an axial direction. The piston(316) may be slidably received within the chamber(312) of the cylinder assembly(310). The inner back iron assembly(352) may be positioned in the driving coil(366). The planar spring assembly(500) may be mounted to the inner back iron assembly(352). The planar spring assembly(500) may include a first planar spring(510), a second planar spring(510) axially spaced apart from the first planar spring(510), and a polymer shim layer(540A, 540B) disposed between at least a portion of the first planar spring (510) and the second planar spring (510) . The linear compressor (300) provided with the polymer shim layer (540A, 540B) can reduce or mitigate the effects of fretting fatigue at the planar spring assembly (500).
