Abstract: A compensated pressure regulator for fluid under pressure including a hollow body, at least one intake for a fluid at high pressure, at least one outlet for this fluid at low pressure, a mobile regulation piece which slides in a cylindrical bore, able to stop the intake of the fluid at high pressure, and such that it includes a piece of generally cylindrical form with two heads of which the two partial inner and opposing faces are of quasi-equal surface; these two partial inner faces, a part of a bore surrounding the piece in a seal-tight manner and a seal integral with this bore delimits a high-pressure chamber, and the piece with two heads and this bore being mobile in relation to one another, and the intake for the high-pressure fluid emerges laterally in this high-pressure chamber, which fluid transmits to the mobile regulation piece loads which are cancelled out.

Abstract: A pneumatic component for the controlled micro-diffusion of gas, intended to be fastened to a pressurized gas reservoir having an aerosol valve. The pneumatic component includes a hollow body whose inner portion has at least one upper chamber enclosed by a leaktight, moving shutter, and a fastening system designed to cooperate in a leaktight manner with the upper part of the container. At least one lower chamber of the pneumatic component is formed, once the component has been fastened to the container, between the shutter and the upper part of the container. The shutter bears against the valve, and a lateral orifice in communication with the lower chamber is designed to expel gases from the container to the outside of the pneumatic component.
