  • Pneumatic regulating pressure reducing valve
    Patent number: 5971013
    Abstract: In a pneumatic pressure-reducer, the control rod for the control valve is supported and guided by two spring washers whose radial stiffness is at least around 200 times greater than the axial stiffness. Each washer comprises internal and external annular regions connected by at least three inclined arms, separated by openings. Preferably, a restriction is formed between a region of the pressure-reducer situated downstream from the valve and a comparison chamber, the pressure of which acts on a comparison capsule connected to the rod.
