Abstract
Improved check valve, characterized essentially by the fact of comprising a valve body of rigid material, in the manner of a sleeve screwed internally at both ends and having a reduction in its internal diameter integrating the valve seat on one of its sides, while the opposite side and on the side wall of the valve body, there is an annular recess for retaining radial pins integral with a tubular body coaxial to the valve body, and whose tubular body acts as a guide for the longitudinal displacements of a rod. Carrier at one end of the valve head, which in its sealing position is adapted to the valve seat; because the other end of the rod opposite the head emerges from the guide and is integral with a piece provided with an annular projection for retaining a helical spring wound on said guide and retainer piece, and comprised between the projection of this latter piece and the members thereof. Radial arms of the guide, so that in the rest position of the spring, the head remains applied against its seat, in the sealing phase; and because the pressure of the circulating fluid overcomes the action of the spring causing the displacement of the head of its seat, consequently opening the valve, the stroke of the stem being determined by the aforesaid part integral with the end thereof.
