Abstract

PURPOSE: To prevent oil leakage by interposing both a sleeve plate provided with a communicating orifice and an elastic sealing member between a cylinder block and a valve plate.
CONSTITUTION: A sleeve plate 33 provided with a communicating orifice 35 between a cylinder block 11 and a valve plate 25, while at one side face of the sleeve plate 33 a sealing member 37 sealing said communicating orifice 35 is elastically interposed in order to hold the suitable degree of freedom in the gap of the side faces. By this construction, the sleeve plate 33 is brought into intimate contact with the valve plate 25, while sealing by the sealing member 37 on the opposite side face and the gap between the sleeve plate 33 and a cylinder block 11 is allowed to hold a suitable degree of freedom by the sealing member 37, so that a sliding face between the sleeve plate 33 and the valve plate 25 is always maintained in close contact condition.
