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.
