Claim Text:
1. A reciprocating compressor with a gas bearing, the reciprocating compressor comprising: a cylinder having a compression space; a piston inserted into the compression space, that reciprocates relative to the cylinder; a discharge valve configured to be attachable to and detachable from a front end surface of the cylinder, to selectively open and close the compression space of the cylinder; a discharge cover having a discharge space that selectively communicates with the compression space by the discharge valve, and coupled to a front end of the cylinder, a gas bearing that lubricates a bearing surface of the cylinder and the piston by gas; and a plurality of resonant springs that supports both sides of the piston in a motion direction, wherein the plurality of resonant springs includes at least one first resonant spring and at least one second resonant spring in the form of compression coil springs, and provided, respectively, on the both sides of the piston, wherein a plurality of at least one of the first resonant spring or the second resonant spring is provided, wherein the plurality of resonant springs is arranged such that lines orthogonal to front end surfaces of at least two of the plurality of resonant springs in a winding direction meet at one point, and wherein the gas bearing includes:
