ABSTRACT:
A fixing bolt is inserted into a through hole of an end-face member and screwed with a screw hole of a valve holding member, by which a discharge valve is sandwiched by the end-face member and the valve holding member. Thus, since a thickness of the end-face member can be provided thinner, a capacity of a discharge hole of the end-face member is made smaller so that degradation of operating efficiency as well as increase of operating noise are prevented.
