ES246331U - Key for high pressure fluids (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

1.key for fluids at high pressure, characterized in that it comprises two bodies mounted concentrically, and with the possibility of limited rotation with respect to each other; one of the bodies, consisting of a piston, is provided at the ends with blind axial holes, although communicated from the bottom with the periphery by radial holes, so that in the axial entry orifice there is a radial bore and in the of output two radial drills; the second body consists of a cylinder that surrounds the piston and involves a lateral internal duct with two radial outwards inwards, so that in a certain position they come to coincide with one of the radial holes of the inlet and outlet ducts, producing the continuity of the circuit, or its sealing by turning, at which time, the second radial hole of the outlet conduit communicates with a lateral hole provided in the cylindrical body, so that evacuation or purging of the closed circuit occurs. 2.lave for fluid pressure can, according to the preceding claim, characterized in that the ends of the plunger part are threaded to allow their coupling to the network. 3.lave for fluids at high pressure, according to previous claims, characterized in that each of the radial passages of the piston have a cajeado to accommodate elastic seals. 4.alve for high pressure fluids, according to previous claims, characterized in that sealing O-rings are interposed between the piston and the enclosing cylinder to avoid fluid leakage during maneuvers. 5.key for high pressure fluids.
