摘要： A reciprocating compressor with a gas bearing is configured to support a portion between a cylinder and a piston by the gas bearing and induce a resonating motion of the piston by the use of compression coil springs. Therefore, a proper resonating motion of a vibrating body can be induced by the use of the gas bearing, without using plate springs, and accordingly manufacturing costs and the number of assembly processes can be reduced and the installation direction of the compressor can be freely designed.
