A damped poppet valve is disclosed. The valve has a valve element movable into and out of engagement with a valve seat to open and close the valve. A damping piston attached to the valve element is slidably received within a damping chamber along a path of travel toward and away from the valve seat. The chamber has an orifice which is small relatively to the cross-sectional area of the piston. The piston forces fluid through the orifice as it moves along the path of travel, thereby damping motion of the valve element.
