Abstract: A linear compressor or sealed system may include a casing, a piston, an driving coil, an inner back iron assembly, and a planar spring assembly. The casing may include a cylinder assembly defining a chamber along an axial direction. The piston may be slidably received within the chamber of the cylinder assembly. The inner back iron assembly may be positioned in the driving coil. The planar spring assembly may be mounted to the inner back iron assembly. The planar spring assembly may include a first planar spring, a second planar spring axially spaced apart from the first planar spring, and a polymer shim layer disposed between at least a portion of the first planar spring and the second planar spring.
