b record with a cylindrical shutter rotation with gaskets tu00f3ricos for devices to d gas.The record is of the kind comprising a body housing formed by two parts rosqueu00e1veis to tubes of provision of gas and to a corresponding device or the installation of consumption that is actionable ATRAThrough a vane drive, used as a key passage and controls the amount of fluid.Which, for the purpose of eliminating the possibility of leak of fluid and to optimize its construction by reducing the cost of manufacture and maintenance.The rotatable male regulating the passage of fluid fuel is composed of a cylindrical body in which at least the area next to the piston actuator is provided with a groove with a ring t.u00f3rico seal; and the surface of the male body contour is formed preferably in a pair of throats of the circular contour in which infest their rings tu00f3ricos sealingWhile these Gorges diametrically opposed to each other and parallel arranged with respect to a plane containing the axis of the cylindrical body.The sections in U of constant depth is around the perimeter of each throat its hub at center of circular section correspondingly, defining its inclination angle.
