Abstract

Improved fluid valve, comprising a spherical seal, which includes a diametral cylindrical passage and a radial appendix, with a shrouded end, provided with a peripheral groove with a sealing ring, whose shutter is disposed in the passage of the fluid, between paths together, rotating around the axis of the radial appendix, which emerges through a second transverse conduit, is essentially characterized in that said shroud of the radial appendix of the spherical obturator, receives the coupling, under pressure from the edge of an independent plate, whose opposite edge remains facing, at the end of an expansion spring occluded in the axial cavity of a cylindrical bushing, whose front edge comprises a diametral groove, which establishes a movable axial coupling with said independent plate and appendix, while the opposite end of said bushing, faceted, receives the conventional coupling of a drive knob; while said front edge of the bushing has an external radial appendage, which plays in an internal lateral race of the passage of a cap-flange for selective retention of said bushing, said race making its partial rotation and its axial displacement against said spring; so that the axial pulsation or displacement of the knob and said bushing, and its selective rotation, governed by said regatta, determine the opening of the conduit, while the rotation in the opposite direction of the knob, determines the closure of the conduit and the axial recoil of the bushing, in this situation the bushing retained radially through the crimp between the bushing appendix and said raceway of the lid-flange, the closing position being ensured.
