La presente invención trata de un regulador de presión variable para de soplete de gas.The present invention relates to a regulator of variable pressure for gas torch.

En los sopletes de gas ya se conocen dispositivos reguladores de la presión para dejar pasar un pequeño caudal de gas a presión desde una cámara primaria de entrada de gas (en comunicación con la bombona de suministro) hasta una cámara secundaria de salida de gas (en comunicación con el quemador del soplete). También se conoce el hecho de disponer de fábrica estos reguladores en el interior del propio soplete, con lo cual la regulación es de presión constante y determinada en origen sin posibilidad de posterior regulación "in situ" por parte del usuario de acuerdo con sus necesidades reales de cada trabajo concreto.In gas torches, pressure regulating devices are already known to allow a small flow of pressurized gas to pass from a primary gas inlet chamber (in communication with the supply cylinder) to a secondary gas outlet chamber (in communication with the torch burner). It is also known to have these regulators factory inside the torch itself, which means that the regulation is of constant pressure and determined at the source without the possibility of subsequent regulation " in situ " by the user according to their real needs of each concrete work.

El objeto del invento es un regulador integrado en el propio soplete y que permite al usuario variar la presión del pequeño caudal de gas que se suministra desde la cámara primaria de entrada de gas hasta la cámara secundaria de salida de gas.The object of the invention is an integrated regulator in the torch itself and that allows the user to vary the pressure of the small flow of gas supplied from the primary chamber of gas inlet to the secondary gas outlet chamber.

El regulador según la invención, integrado en el propio soplete, consta de una membrana pre-tarada mediante sendos muelles, que la presionan en contraposición para dejar pasar un pequeño caudal de gas a presión desde una cámara primaria de entrada de gas hasta una cámara secundaria de salida de gas cuando se equilibran las fuerzas de cierre y las fuerzas de apertura. En su funcionamiento:The regulator according to the invention, integrated in the own torch, consists of a pre-tared membrane by means of two springs, which press it in contrast to let a small flow of pressurized gas from a chamber primary gas inlet to a secondary outlet chamber of gas when the closing forces and the forces of opening. In its operation:

a) la membrana es presionada en un sentido (de apertura) por la acción de un primer muelle alojado de forma fija en una cajera conformada en el cuerpo interior del soplete de gas;a) the membrane is pressed in one direction (from opening) by the action of a first spring housed in a fixed way in a pocket formed in the inner body of the torch gas;

b) la membrana es presionada en un sentido opuesto (de cierre) por la acción de un segundo muelle alojado de forma regulable en una cajera conformada en un tornillo;b) the membrane is pressed in one direction opposite (closing) by the action of a second spring housed from adjustable shape in a pocket shaped on a screw;

c) el tornillo va roscado directa o indirectamente al cuerpo del soplete y es actuable en giro desde el exterior a través de un orificio de acceso conformado en la carcasa del soplete de gas;c) the screw is directly threaded or indirectly to the torch body and is rotatable from the outside through an access hole formed in the housing of the gas torch;

d) el tornillo dispone de un limitador de recorrido que establece las presiones mínima y máxima entre las cuales está comprendida la presión de salida.d) the screw has a limiter path that establishes the minimum and maximum pressures between which is included the outlet pressure.

En particular, la presión del caudal de gas está comprendida entre O \leq P \leq 4 Bar y, preferentemente, entre 2 \leq P \leq 3 Bar.In particular, the gas flow pressure is between O ≤ P ≤ 4 Bar and, preferably, between 2 ≤ P ≤ 3 Bar.
