Linear compressor with a plurality of support springs and a dual compression unit

Abstract

In a compressor, a yoke constituting a linear drive section together with a driver coil, through which magnetic fluxes from a permanent magnet pass, is integrated with a cylinder and a container. A piston inserted into the cylinder is supported by springs, and the other end thereof faces an operating-gas-compressing space. The linear drive section is arranged parallel to the piston in a diametrical direction thereof. This construction reduces the longitudinal dimension of a piston portion. Further, a plurality of parts is combined together in a main body block, thereby reducing the number of parts required and improving the assembly accuracy.
