Abstract:
1. An oscillating linear compressor comprising: a cylindrical chassis defining a chamber and comprising a plurality of elongated frame members extending between either end of said chassis; a compression cylinder concentrically disposed within said chamber and defining a compression chamber; a piston assembly comprising a piston configured to compress fluid within said compression chamber; a push tube extending from said piston assembly out of said compression chamber for bi-directionally actuating the piston within said compression chamber; a voice coil connected to said push tube; a power distribution assembly for coupling current to said voice coil and inducing an oscillating magnetic field about said voice coil, said power distribution assembly comprising a plurality of electrically conductive linear bearings coupled to a power supply and are configured to facilitate substantially frictionless, bi-directional travel of said push tube; and one or more permanent magnets mounted to said plurality of elongated frame members and disposed about the exterior of said cylinder for providing a permanent magnetic field with which said oscillating magnetic field interacts.
