摘要

Unidirectional retention valve for fluids to which several fluid inlets can be connected that converge in a single outlet, comprising a solid body with two inlet ducts that converge in a central cavity from which a single outlet duct divides, each duct of entry comprises a first cavity and a second cavity as a continuation of the first and reaching the central cavity, being disposed within the first cavity a helical spring resting on one end against the side contiguous to the second cavity and at the other end against a shutter, with through holes and a frustoconical portion that rests against a closing washer by the action of the spring when the fluid pressure is lower than the thrust force thereof, the closing washer being retained by a retaining washer disposed to continuation of it.
