ABSTRACT:
A continuously variable V-belt transmission comprises means for producing a signal indicative of state of a hydrodynamic transmission unit which is drivingly connected to a continuously variable V-belt transmission unit. A line pressure regulator valve regulates fluid supplied by a pump in response to the signal to produce a line pressure variable depending upon the state of the hydrodynamic transmission unit.
