  • Patent number: 8276613
    Abstract: Disclosed is a one-way valve of a variable capacity compressor for vehicle including: a valve sheet having a coolant inlet formed at the center; a valve case provided over the valve sheet and having a plurality of coolant discharging ports along the circumferential surface; a spool valve selectively opening/closing the coolant inlet and the coolant discharging port in the valve case; and a resilient member provided between the valve case and the spool valve, wherein the plurality of coolant discharging ports are spaced from each other by a predetermined distance and one of the plurality of coolant discharging ports is closed so that the spool valve is brought in tight contact with an inner wall surface of the valve case when the coolant discharging ports are initially opened not to be swayed left and right.
