Claims

[Scope of utility model registration request]

In a reciprocating compressor that compresses and discharges suction fluid by reciprocating a piston within a cylinder, pressure is provided at the outer end of the cylinder to release fluid pressure remaining in a dead space within the cylinder. The pressure relief valve has a valve body that opens and closes the opening opening into the dead space, and this valve body is operated by the fluid pressure on the discharge side guided to the other end and the biasing force of the spring. A reciprocating compressor, characterized in that the opening is normally closed and the opening is opened by the pushing force of the piston.
