The valve has a seat and plate coupled together to define a shallow chamber therebetween, and a thin, metal, valving disc is freely movable, through the chamber, between the seat and plate. The disc has a metering orifice in the center thereof for communicating with a registering larger, central orifice in the plate. The seat has four orifices, circumscribing the center of the seat, for addressing “unseating”fluid pressure to the disc.

A uni-directional flow, fluid valve, comprising: first means defining a circular valve seat; second means defining a circular valve plate; an annular seal; and third means holding said seat and said plate in a mutually confronting relationship with said seal therebetween in interfacing and sealing engagement with both said valve seat and said valve plate; wherein said seat and said plate have means which, with said seal, cooperatively define a cylindrical, fluid-sealed chamber therebetween; and a circular valving element having a given outside diameter, confined in said chamber, and freely and wholly movable between first and second spaced apart positionings therewithin; wherein said valving element is formed of metal, and is very thin, lightweight, and supple; said seat, plate and said element are orificed to accommodate fluid flow, sequentially, through one of said first and second means, through said element, and through the other of said first and second means; said seat, plate and said element have means cooperative (a) to prohibit such aforesaid sequential fluid flow therethrough, upon said element being in one of said first and second positionings, and (b) to permit such fluid flow therethrough, upon said element being in the other of said first and second positionings; and said element and a given one of said first and second means have orifices formed therein, as aforesaid, which are always in substantially common, coaxial alignment or registry, always to accommodate fluid flow therebetween; wherein said element comprises means responsive only to fluid pressure addressed thereto (a) through one of said first and second means, for moving said element, wholly, from one of said first and second positionings to the other thereof, and (b) through the other of said first and second means, for moving said element, wholly, from the other of said first and second positionings to said one positioning; the other of said first and second means has orifices formed therein, as aforesaid, which are always out of registry with any orifice in said element; said valve plate has a circumferential wall which, with said seal and said seat defines said fluid-sealed chamber, and has an inside diameter which is approximately ten percent greater than said given outside diameter of said valving element to accommodate said valving element nestably therewithin; and said orifice in said given means is (a) substantially smaller in diameter than said given outside diameter of said valving element, and (b) larger in diameter than said orifice in said element.
