Abstract

A discharge valve mechanism in a compressor for compressing refrigerant gas includes a valve plate and a discharge valve plate. The valve plate forms a discharge port into which the compressed refrigerant gas is discharged. The discharge valve plate is located between the valve plate and a rear housing and includes a support portion, a connecting portion and a discharge valve. The support portion is sandwiched between the valve plate and the end surface of the rear housing. The connecting portion is bendably cantilevered from the support portion. The connecting portion extends to an opposite side of the discharge port so as to bypass the discharge port from the support portion. The connecting portion has a free end portion. The discharge valve extends from the free end portion to the discharge port toward the support portion for opening and closing the discharge port.

Description

BACKGROUND OF THE INVENTION

[0001] The present invention relates to a discharge valve mechanism in a compressor that is used for an air-conditioner.

[0002] Japanese Unexamined Patent Publication 10-141230 discloses a discharge valve mechanism in a compressor. Referring to FIG. 8, a gasket 106, a valve plate 109, a suction valve plate 111, a discharge valve plate 113 and a gasket 115 are interposed between a cylinder block 102 having formed therein a compression chamber 101 and a rear housing 105 having formed therein a suction chamber 103 and a discharge chamber 104 in the compressor. The valve plate 109 has formed therein a suction port 107 and a discharge port 108, and the suction valve plate 111 has formed therein a suction valve 110 for opening and closing the suction port 107. Also, the discharge valve plate 113 has formed therein a discharge valve 112 for opening and closing the discharge port 108, and the gasket 115 has formed therein a retainer 114. A piston (not shown) reci...
