Abstract
Improvements in double-check valves, characterized by comprising a body with an axial chamber in its interior, a pair of axially aligned and laterally arranged entrance passages, an exit passage connected with said chamber between the entry passages, a pair of packings adjacent to the entry steps; an annular edge with a prolonged closing towards the inside in the packings surrounding the respective entry passages; a double-action shuttle valve element housed in the axial chamber and having opposite closing faces prepared to be adjusted for sealing at the respective closing edges, when said element is displaced towards one or the other by the pressure of the fluid in one of the entry passages, which is higher than the pressure in the other step, by means of which the first entry passage connects to the exit passage, while this is disconnected from the second entry passage .
