Compressor

摘要

A compressor includes a discharge chamber, compressor chamber, valve plate, and discharge reed valve. The valve plate includes a fixing surface, exposed to the discharge chamber, and a discharge port, which communicates the discharge chamber and the compression chamber. The discharge reed valve includes a fixed portion, fixed to the fixing surface, a base portion, separable from the valve plate, and a valve portion, which closes the discharge port. The valve plate includes an annular seal surface, recessed groove, receiving surface, and support surface. The seal surface contacts the valve portion around the discharge port. The recessed groove is arranged in the fixing surface outward from the seal surface. The receiving surface is flush with the fixing surface and contacts a distal region of the valve portion. The support surface is flush with the fixing surface and contacts a central region of the valve portion.

1. A compressor comprising:
a discharge chamber; a compression chamber; a valve plate arranged between the discharge chamber and the compression chamber, wherein the valve plate includes a fixing surface, which is exposed to the discharge chamber, and a discharge port, which communicates the discharge chamber and the compression chamber; and an elastically deformable discharge reed valve including a fixed portion, which is fixed to the fixing surface in contact with the fixing surface, a base portion, which extends in a longitudinal direction of the discharge reed valve from the fixed portion and is separable from the valve plate, and a valve portion, which further extends in the longitudinal direction from the base portion to open and close the discharge port, wherein the valve portion has a distal region including an edge at a distal end in the longitudinal direction, and the valve plate includes
an annular seal surface that is flush with the fixing surface and can come into contact with the valve portion around the discharge port,a recessed groove located outward from the seal surface and arranged in the fixing surface, wherein the recessed groove includes a bottom separated from the edge of the valve portion,a receiving surface that is flush with the fixing surface and comes into contact with the distal region, andan extended portion that extends from the receiving surface toward the center of the discharge port, wherein the extended portion is continuous with the seal surface and flush with the fixing surface, wherein:the extended portion includes a support surface that comes into contact with a central region of the valve portion; and one of a communication groove arranged in the support surface and that comes into communication with the discharge port when the discharge port is closed, and a recessed portion arranged in the support surface and that does not come into communication with the discharge port when the discharge reed valve is closed.
