  • Pressure regulator
    Patent number: 8646748
    Abstract: A fluid pressure regulator includes a regulation chamber arrangement in which a piston is received, in the regulation chamber arrangement, a first chamber and a second chamber being defined by opposite parts of the piston. The first chamber and the second chamber include respectively a first inlet and a second inlet for the fluid, the first inlet and the second inlet being connected to a first environment at a first pressure. The first chamber and the second chamber include respectively a first outlet and a second outlet for the fluid, the first outlet and the second outlet being connected to a second environment at a second pressure. The piston is movable in the regulation chamber arrangement in response to a variation of pressure of the fluid in the first chamber to open/close the second outlet to regulate the second pressure. The fluid pressure regulator includes a valve device to open/close the first outlet to induce the pressure variation in the first chamber.
