Claims

[Scope of utility model registration request]

A cylinder provided with a piston, a conical valve opening coaxial with the cylinder center and gradually narrowing from the cylinder side at the open end of the cylinder, and an annular suction hole with a larger diameter than the valve opening on the inner surface of the cylinder side. a first valve seat plate that communicates with the suction hole and has one end open to a suction chamber in the cylinder cover; an annular suction valve that is provided on the first valve seat plate and opens and closes the suction hole; It has a disc shape that is attached with a predetermined gap from the valve opening end on the discharge chamber side in the cover, and has multiple mounting feet integrally molded on the outer periphery, and has a fully polygonal outer shape that is coaxial with the valve opening at the center of the inner surface. A valve guide integrally formed with the formed support part, a support bolt inserted into the support part of the valve guide from the cylinder side, and a head of the support holder facing the valve opening of the support part. a second valve seat plate installed between the end face and having an annular discharge hole; and a second valve seat plate that is placed on the valve guide side surface of the second valve seat plate to open and close the discharge hole and has an inner peripheral shape. A refrigerant compressor comprising: a discharge valve having a polygonal shape and fitted to a supporting portion of the valve guide; and a valve spring inserted between the discharge valve and the valve guide. −゛
