Abstract

Bi-directional load valve for gas lighters, of the type comprising cylindrical valve seat and body, with internal housing for the sealing piston, both externally threaded and with tight sealing seals on the reservoir carrying said valve, characterized in that the valve body, has a void by configuring two cylindrical compartments of different diameter, with a frustoconical portion of connection between both, presenting the compartment of smaller diameter output to the outside in a cavity of the valve seat and, to the larger diameter communicated with the reservoir through an orifice prolonged tubularly towards the interior of the valve body and located in the center of a basic closing element for said compartment; in all the width of the emptying and on the walls of the compartments of smaller diameter and frustoconical portion sits the sealing plunger, mobile, exterior surface geometrically analogous to the emptying, with clearance in the compartment of greater diameter, an axial channeling open to the outside in the cavity of the valvular seat, and said channeling communicated internally by the frustoconical zone with the said interparietal loose portion; and also presenting said piston, a cavity in its portion of greater diameter open towards the tubular orifice communicating with the reservoir, which receives, partially, said tubular portion and a closing safety spring surrounding it; the aforementioned sealing plunger constituting the opening element of the valve under the load pressure on the bed of the seat in which its channeling emerges and, closing under the internal pressure of the tank, by hermetic adjustment of the complementary frustoconical zones of said plunger and the accommodation that comprises it.
