Abstract
Abstract A valve controls the rate of flow of fluid through its outlet pasage by selective alignment with the passage of a jet having an orifice of area less than that of the outlet passage. A plurality of jets in a single valve provides variable flow rate control and interchangeability of jets allows use of the same valve in a wide variety of applications and environs. The same valve can further be easily adapted for continuous or intermittant flow operation.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
169 words
A valve comprising: a cylindrical chamber having a fluid inlet passage and a fluid outlet passage, said outlet passage being in an end wall of and displaced from the axis of said chamber; a cylindrical member disposed in said chamber for rotation about the axis of said chamber, said member having a plurality of sockets extending therethrough, said sockets being angularly displaced along a circular path equally displaced as said outlet passage from said axis; a plurality of jets, one disposed in each of said sockets and against said end wall of said chamber for rotation with said member into and out of alignment with said outlet passage, each of said jets having an orifice therethrough of area less than the area of said outlet passage whereby fluid flow through said outlet passage may be restricted; and means for spacing said member from the chamber wall containing said outlet passage, whereby fluid flow through said outlet passage continues when none of said orifices is aligned with said outlet passage.
Claim 2
Dependent Claim
169 words
A valve comprising: a cylindrical chamber having a fluid inlet passage and a fluid outlet passage, said outlet passage being in an end wall of and displaced from the axis of said chamber; a cylindrical member disposed in said chamber for rotation about the axis of said chamber, said member having a plurality of sockets extending therethrough, said sockets being angularly displaced along a circular path equally displaced as said outlet passage from said axis; a plurality of jets, one disposed in each of said sockets and against said end wall of said chamber for rotation with said member into and out of alignment with said outlet passage, each of said jets having an orifice therethrough of area less than the area of said outlet passage whereby fluid flow through said outlet passage may be restricted; and means for spacing said member from the chamber wall containing said outlet passage, whereby fluid flow through said outlet passage continues when none of said orifices is aligned with said outlet passage.
Claim 3
Dependent Claim
35 words
The valve according to claim 1, said orifices having areas of varied predetermined sizes, said valve further comprising means for locating and securing any selected one of said jets in alignment with said outlet passage.
Claim 4
Dependent Claim
45 words
The valve according to claim 1, the angular displacement between said sockets and the areas of said orifices and said outlet passage being such as to prevent flow of fluid through more than one of said orifices to said outlet passage at the same time.
Claim 5
Dependent Claim
26 words
The valve according to claim 1 further comprising means for prepositioning said jets firmly against said chamber wall prior to flow of fluid through said jets.
Claim 6
Dependent Claim
33 words
The valve according to claim 1, said spacing means providing a gap between said member and said chamber wall of dimension predetermined to restrict the continuous flow of fluid through said outlet passage.
