ABSTRACT:
A valve includes a body member having spaced apart first and second fluid passages and a bore in communication with the passages. The bore includes a valve seat interposed at one end of the bore between the first and second fluid passages, a discharge chamber opposite the first fluid passage and between the valve seat and the second fluid passage, and a valve spring cavity/dampening chamber at the end of the bore distal from the seat. The valve has a poppet engaged and yieldingly urged into sealing engagement with the valve seat by a spring disposed in the valve spring cavity. The poppet has a seating portion at its forward end, a stem portion at its rearward end, and a raised central portion interposed therebetween. Part of the poppet is guidingly received by the spring cavity in a controlled clearance fit so as to allow fluid to exert dampening pressure on the spring and guide the poppet in an axial direction. Improved valve performance is benefits are also realized when the central portion includes a vent groove thereon.
