Abstract

A reciprocating compressor is provided. The reciprocating compressor may include a cylinder having a compression space, a piston inserted into the cylinder to define the compression space while being reciprocated, the piston having a suction passage to communicate with the compression space, a gas bearing having at least one bearing hole that passes through the cylinder, so that a refrigerant gas may be injected between the cylinder and the piston to support the piston with respect to the cylinder, and a flow resister disposed at an outer circumferential surface of the cylinder or at one side of the cylinder to restrict a flow of the refrigerant gas flowing through or toward the at least one bearing hole.
