Abstract

PURPOSE: To reduce the clearance volume by providing the central portion of a valve seat with a delivery port inflow opening into which the projection of a piston end will fit and by eccentrically providing the opposite cylinder side of the valve seat with an outflow opening which connects to the delivery port inflow opening.
CONSTITUTION: A suction port 7 forcooling medium is eccentrically pierced into a valve seat 5. The cylinder 2 side central portion of the valve seat 5 is provided with a delivery port inflow opening 10 into which the projection, additionally provided at the central end portion 3a of a piston 3, will fit, and the opposite cylinder 2 side of the valve seat 5 is eccentrically provided with a delivery port outflow opening 11 which connects to the delivery port inflow opening 10. Because the delivery port outflow opening 11 is positioned eccentrically, it is no obstacle for easy assembling although the middle parting will 6a of a valve cover 6 is linearly positioned at the central portion. Furthermore, the top clearance volume of the piston can be reduced, resulting in the improvement of the compression efficiency.
