(54)	VALVE ASSEMBLY AND SYSTEM INCLUDING SAME FOR CONTROLLING FLUID FLOW TO AND FROM A CLUTCH

(57) A system (20) for controlling fluid flow to and from a clutch (16) includes a motor (24), a pump (22), and a valve assembly (26). The valve assembly includes a housing (28) defining an interior (38). The housing defines a first orifice (40) operably coupled to the pump and a second orifice (42) operably coupled to the clutch. The valve assembly also includes a piston (54) operably coupled to the motor and disposed within the interior of said housing. The piston is movable between a first position for allowing the fluid flow between the first orifice and the second orifice, a second position for obstructing the fluid flow between the first orifice and the second orifice, and a third position for limiting the fluid flow between the first orifice and the second orifice. The valve assembly additionally includes a biasing member (53) coupled to the piston. The biasing member biases the piston toward the first position.
