Abstract
Abstract A means for controlling fluid flow including a housing having an inlet port adapted to be connected to a source of fluid under pressure and also having a discharge port adapted to be connected to an apparatus requiring controlled fluid flow or pressure. The housing has a passageway means provided therein between the inlet and outlet ports and is in communication therewith. A valve means is movably mounted in the housing and is adapted to selectively close the passageway at times. The valve means includes an O-ring movably mounted thereon which is adapted to selectively close the passageway means when the valve means is moved in one direction with respect to the housing and to selectively open the passageway means when the valve means is moved in an opposite direction with respect to the housing. A resilient means is also provided in the housing to normally bias the valve means in the said opposite direction.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
185 words
A means for controlling fluid flow, comprising, a housing having inlet and outlet ports formed therein, said inlet port adapted to be connected to a source of fluid pressure, said outlet port adapted to be connected to an apparatus requiring controlled fluid pressure, said housing having a passageway means provided therein between said inlet and outlet ports and being in communication therewith, a valve means movably mounted in said housing adapted to selectively close said passageway means at times, said valve means including an O-ring movably mounted thereon and adapted to selectively close said passage way means when said Valve means is moved in one direction with respect to said housing and to selectively open said passageway means when said valve means is moved in an opposite direction with respect to said housing, said valve means including a base portion having a peripheral skirt portion extending transversely therefrom which movably embraces said O-ring with said skirt portion causing said Oring to roll upon itself on said valve means as said valve means is moved, and means normally biasing said valve means in said opposite direction.
Claim 2
Dependent Claim
185 words
A means for controlling fluid flow, comprising, a housing having inlet and outlet ports formed therein, said inlet port adapted to be connected to a source of fluid pressure, said outlet port adapted to be connected to an apparatus requiring controlled fluid pressure, said housing having a passageway means provided therein between said inlet and outlet ports and being in communication therewith, a valve means movably mounted in said housing adapted to selectively close said passageway means at times, said valve means including an O-ring movably mounted thereon and adapted to selectively close said passage way means when said Valve means is moved in one direction with respect to said housing and to selectively open said passageway means when said valve means is moved in an opposite direction with respect to said housing, said valve means including a base portion having a peripheral skirt portion extending transversely therefrom which movably embraces said O-ring with said skirt portion causing said Oring to roll upon itself on said valve means as said valve means is moved, and means normally biasing said valve means in said opposite direction.
Claim 3
Dependent Claim
18 words
The means of claim 1 wherein said O-ring movably embraces a sleeve means positioned in said passageway means.
Claim 4
Dependent Claim
148 words
The means of claim 2 wherein said housing includes opposite ends, said passageway means being between said opposite ends, one of said ends being selectively threadably closed by a cap means having inner and outer sides, an adjustment screw threadably movably mounted in the outer end of said housing and being movable towards and away from said cap means, said adjustment screw having inner and outer ends, said housing means including a first spring means operatively engaging the inner end of said screw and extending therefrom, said valve means being positioned between said screw and said cap means, said first spring means engaging said valve means and normally biasing said valve means towards said cap means, said sleeve means partially embracing said first spring means and having a peripheral flange portion, said flange portion and said housing defining said passageway means, said O-ring movably embracing said flange portion.
Claim 5
Dependent Claim
29 words
The means of claim 3 wherein a second spring means is positioned between said valve means and said cap means normally biasing said valve means in said one direction.
Claim 6
Dependent Claim
43 words
The means of claim 3 wherein said screw has a bore formed therein extending therethrough, the interior of said sleeve being in communication with said screw bore to permit the interior of said sleeve to communicate with the atmosphere outside of said housing.
