Abstract

Improved arrangement in unidirectional valves, because according to the same within the body of the valve, open at its ends, is arranged a helical recovery spring slightly compressed between each washers provided with recesses for the passage of fluid through them, the which. Washers one of them. Remaining static makes spring seat functions, while the other is movable with possibility of axial displacement, both the washers and said spring mounted coaxially on the stem or tail of an axially displaceable valve element, passing through said body of the the valve projects out of it at the end corresponding to the outlet of the fluid, constituting itself in the valve head, which has an extreme annular projection followed by a zone of smaller diameter, in which it has engaged a catch for the fitting of an O-ring for the hermetic seal of the exit mouth of the fluid, provided that at the end of the shank of the valve element, a retainer and thrust piece supported on the mobile washer is mounted coaxially, so that the valve element determines the closure of the valve. The valve when the fluid supply is cut, but once it is established it is in the open position by the at own pressure that the fluid can exert as it passes through the valve.
