LINEAR COMPRESSOR AND FLAT SPRING ASSEMBLY

WIPO Patent Application WO/2023/131080

A1

A linear compressor (300) or a sealing system, the linear compressor (300) comprising a housing (308), a piston (316), a drive coil (366), an inner back iron assembly (352), and a flat spring assembly (500). The housing (308) comprises a cylinder assembly (310), which defines a compartment (312) in an axial direction. The piston (316) is slidably accommodated in the compartment (312) of the cylinder assembly (310). The inner back iron assembly (352) is positioned in the drive coil (366). The flat spring assembly (500) is mounted to the inner back iron assembly (352). The flat spring assembly (500) comprises a first flat spring (510); a second flat spring (510), which is axially spaced apart from the first flat spring (510); and a polymer shim layer (540A, 540B), which is arranged between at least part of the first flat spring (510) and the second flat 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 flat spring assembly (500).
