Abstract
A main discharge port is formed at a center of a fixed base plate. An auxiliary discharge port is formed in a portion of the fixed base plate that is different from the main discharge port. The main discharge port includes a main recess that opens toward a main reed valve so as to increase a cross-sectional area of a flow passage for the fluid. The auxiliary discharge port includes an auxiliary recess that opens toward an auxiliary reed valve so as to increase a cross-sectional area of a flow passage for the fluid. A sealing surface area, with which the fixed base plate and the auxiliary reed valve are in contact with each other to seal the auxiliary recess, is larger than a sealing surface area with which the fixed base plate and the main reed valve are in contact with each other to seal the main recess.
