Innovative Free-Piston Compressor Based on Generalized Conception of Compressors Driven by an Oscillating Electrical Motor

This paper deals with generalized approach to the reciprocating piston compressor driven by oscillating electrical motor and possibilities of development of new structures of the device. The current term linear compressor, ipso facto, restricts the considered devices only with a linear motion of the piston. Therefore the more general term oscillating motor-compressors is used in the paper, in which the samples of the considered devices are analyzed. The structure of lately created innovative free-swinging pistons compressor driven by oscillating rotating electrical motor is presented in the paper. The proposed compressor has many advantages to compare with the traditional devices: compactness, reduced frictional losses, reduced wear of the pistons and cylinder surfaces, full balanced mechanical system without vibration of the frame, optimal magnetic circuit of the oscillating rotating electrical motor, etc. In this way the expedience of the generalized conception is demonstrated.
