ABSTRACT:
A variable speed transmission including a rotatable input member connectable to a drive source, a pump for pumping fluid through a conduit, a gear train including an epicyclic gear train operatively coupled to the input member and the pump, and a rotatable output member selectively operatively connected to either a forward or a reverse drive gear, wherein the output member has a forward drive ratio corresponding with its connection to the forward drive gear and a different, reverse drive ratio corresponding with its connection to the reverse drive gear. The transmission may also include a pressure compensating flow metering device for regulating the pressure of fluid flowing through said conduit.
