Abstract:
An unloader valve includes a seat including a plurality of inlet apertures spaced apart from one another and extending through the seat along one of a plurality of parallel inlet axes. A manifold plate is fixedly connected to the seat and includes a plurality of outlet apertures, each spaced apart from one another and extending through the manifold plate along one of a plurality of parallel outlet axes. The unloader valve also includes a plurality of plug holes, a control chamber formed in the manifold plate, and a control space fully defined by the manifold plate and arranged to fluidly connect the control chamber and each of the plug holes to one another. The unloader valve also includes a control member disposed within the control chamber and movable between a first position in which the control space is exposed to a pressure source, and a second position in which the control space is isolated and a plurality of plugs, each positioned within one of the plug holes and movable between a closed position in which each plug closes one of the inlet apertures and an open position in which the plurality of inlet openings are in fluid communication with the plurality of outlet openings.
