Abstract

A compressor (32) has a housing (34) to which is fixedly secured a piston (36) disposed axially of the housing. A cylinder (40) is arranged for axial movement relative to and coaxially with the piston to define with the piston a variable volume compression chamber (58). The cylinder carrying an electromagnetic drive coil (62) and the housing contains a magnetic circuit cooperable with the drive coil to cause said axial movement. By arranging for movement of the cylinder relative to a fixed piston, increased reliability and compactness can be achieved.
