ABSTRACT:
A cylinder head for reciprocating compressor comprises a frame including a insertion groove unit so as to make a concentric circle with a through hole penetrated in the body unit; a cylinder in which a cylinder body unit and a flange unit is coupled so as to be located at the through hole of the frame and the insertion groove unit respectively; a discharge cover in which the flange unit formed in the plenum unit is contacted on the step surface of the frame insertion groove; a plurality of volts connected to the step surface; and a valve body for switching the compressing space in the cylinder, thereby the assembling process of components can be simplified and productivity of the assembly can be simplified and productivity of the assembly can be increased by raising assembly accuracy.
