摘要：A fluid valve assembly having a housing with a valve seat which forms a fluidport. A valve is movable along an axis relative to the port between an open and a closedposition. This valve includes a protrusion complementary in shape to, but slightly smallerthan, the port. The protrusion is at least partially positioned in the port when the valve is

in its closed position at which time a clearance space between the port and theprotrusion is sufficiently small to prevent fluid flow through the port. A main springdisposed between the housing and the valve resiliently urges the valve towards its closedposition. A second spring is also operatively positioned between the valve and thehousing which urges the valve away from the valve seat towards its open position andprevents contact between the valve and the valve seat.
