<p>A flow control valve 70 is provided in a primary pulley that is a rotor, and includes a first port 71; a second port 72; a working fluid channel 73 formed between the first port 71 and the second port 72 and through which the working oil passes; a check valve 74 that is formed in the working fluid channel 73 and is opened toward a first-port-side channel 73a from a second-port-side channel 73b of the working fluid channel 73; and a valve-opening control section (a guide member 75, a spool 76, a cylinder 77, and a drive pressure chamber 79) that is arranged at the check valve 74 at the side of the second port, that forcibly opens the check valve 74 when discharging the working fluid from the first port 71 to the second port 72, and increases a channel resistance of the second-port-side channel 73b as an opening amount of the check valve 74 is small. The flow control valve can prevent the over-discharge of the working fluid at the beginning of opening the valve.</p> |
