Claim:
1. A linear compressor, comprising: a cylinder assembly defining a chamber; a piston slidably received within the chamber of the cylinder assembly; a driving coil; an inner back iron assembly positioned in the driving coil, the inner back iron assembly extending between a first end portion and a second end portion along an axial direction, the inner back iron assembly also having an outer surface, the inner back iron assembly comprising a magnet mounted to the inner back iron assembly at the outer surface of the inner back iron assembly such that the magnet faces the driving coil; a first planar spring assembly mounted to the inner back iron assembly at the first end portion of the inner back iron assembly; a second planar spring assembly mounted to the inner back iron assembly at the second end portion of the inner back iron assembly, the first and second planar spring assemblies including a first plurality of fasteners extending in attached engagement with the sleeve; a piston flex mount positioned at the first end portion of the inner back iron assembly; and a compliant coupling extending between the piston flex mount and the piston along the axial direction in order to compliantly couple the inner back iron assembly to the piston, the compliant coupling being compliant along a radial direction that is perpendicular to the axial direction, wherein a magnetic field of the driving coil engages the magnet in order to move the inner back iron assembly along the axial direction relative to the driving coil and to move the piston along the axial direction within the chamber of the cylinder assembly during operation of the driving coil, and wherein one of the first or second planar spring assemblies includes a second plurality of fasteners extending from the one of the first or second planar spring assemblies in attached engagement with a bracket of the driving coil.
