Patent ID: 7438659

Claim:
A device for controlling belt lubrication and cooling of a continuously variable transmission (CVT), comprising: a control portion configured for generating a mechanical signal representative of the CVT shift ratio; wherein said control portion comprises: a valve having a valve housing with a primary port communicating with primary pressure acting on a primary pulley of the CVT and a secondary port communicating with secondary pressure acting on a secondary pulley of the CVT, said ports positioned on opposite sides of a valve spool respectively, said valve spool being moveable in response to pressure acting through said ports; and a control rod cooperating with the valve spool, wherein said signal is a mechanical signal transmitted through said control rod in response to a position of said valve spool; and a fluid supply portion communicating with said control portion and including a fluid nozzle positionable in response to said mechanical signal to direct a cooling fluid alternately at the primary pulley or the secondary pulley of said CVT, comprising: a pinion gear cooperating with a first end of said fluid nozzle for rotation thereof; and a gear rack meshed with said pinion gear and cooperating with said control rod for movement in response said mechanical signal.
