摘要： 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.

摘要： A piston compressor includes a rotary valve having a suction guide hole. A plurality of introducing passages are formed in a cylinder block to connect compression chambers to the rotary valve. The inner circumferential surface of each cylinder bore has a suction auxiliary recess, which is connected to the outlet of the corresponding introducing passage in the circumferential direction of the cylinder bore at the end of the cylinder bore facing a valve assembly. Therefore, the compressor reduces suction resistance of gas at the beginning of the suction stroke without enlarging introducing passages formed in the cylinder block.

摘要： A suction throttle valve of a variable displacement compressor having a compressor housing includes a suction chamber, a crank chamber, an inlet, a suction passage, a valve body, a valve housing, an urging member, a valve chamber, and a communication hole. The valve body is provided for adjusting an opening area of the suction passage and movably arranged in the suction passage. The urging member urges the valve body in the direction that decreases the opening area of the suction passage. The communication hole is provided for connecting the suction chamber to the valve housing. An opening area of the communication hole is variable in accordance with the movement of the valve body. Accordingly, the opening area of the communication hole becomes maximum during the maximum displacement operation of the compressor and becomes reduced during the intermediate displacement operation of the compressor.

摘要： A compressor has a suction throttle valve, which includes a suction passage, a suction port, a valve body, an urging member, a valve chamber, a first communication hole, a closing valve and a valve seat. The closing valve closes the hole of the valve body by pressure difference between the valve chamber and the suction port. The valve seat limits movement of the closing valve toward the suction port. The hole of the valve body is closed when the closing valve is in contact with the valve body, and open when the closing valve is in contact with the valve seat. A communication passage is formed in the closing valve or the valve seat, which enables communication between the hole of the valve body and the suction port when the closing valve is in contact with the valve seat.
