A hydraulic control circuit is disclosed for a continuously variable transmission comprising a continuously variable ratio transmission unit ("variator") 10 , the circuit comprising a supply line 106 and means (which may take the form of a pump 110 ) for providing a flow of pressurised fluid in the supply line, means (which may comprise a pressure control valve 116 ) for generating a back pressure in the supply line, and at least one connection for feeding fluid from the supply line to a hydraulic actuator 100 acting on a movable torque transmission 23 - 37 element (which may comprise a roller 28 ) of the variator 10 . The valve means 152 connected to the supply line allows pressure in the supply line to be selectively modified in response to rate of flow in the supply line. |
