Abstract
Abstract A valve having a valve cavity containing a disk rotated concentrically about an axle having external adjustment means is the subject of this disclosure. The adjustment means adjusts the relative radial position of the axle to the valve body and consequently adjusts the position of the valve disk relative to the valve seat to obtain an efficient seal therebetween without requiring disassembling of the valve. The external radial adjustment means supporting said axle is secured to said valve body.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
180 words
In valves having a disk member which eccentrically rotates in a valve body to make sealing contact with an orifice-like seat, the improvement comprising: a. axle means supporting said disk by an offset member attached to said disk, b. bearing means supporting each end of said axle means, c. said bearing means disposed in an opening in said valve body substantially the same shape as the exterior of said bearing means but having slightly greater peripheral dimensions than the exterior surface of said bearing means, d. adjustment means comprising a pair of adjustable bearing housings in which opposite ends of said axle means are snugly supported, said bearing housings being adjustable radially to the longitudinal axes of said axle means wherein each adjustable bearing housing is secured to said valve body by at least two bole means wherein the bolt holes in said adjustable bearing housing are slightly greater in diameter than said bolt means to accommodate slight radial movement of said adjustment bearing housings relative to said bolt means whereby the ends of said axle means are radially adjustable.
Claim 2
Dependent Claim
180 words
In valves having a disk member which eccentrically rotates in a valve body to make sealing contact with an orifice-like seat, the improvement comprising: a. axle means supporting said disk by an offset member attached to said disk, b. bearing means supporting each end of said axle means, c. said bearing means disposed in an opening in said valve body substantially the same shape as the exterior of said bearing means but having slightly greater peripheral dimensions than the exterior surface of said bearing means, d. adjustment means comprising a pair of adjustable bearing housings in which opposite ends of said axle means are snugly supported, said bearing housings being adjustable radially to the longitudinal axes of said axle means wherein each adjustable bearing housing is secured to said valve body by at least two bole means wherein the bolt holes in said adjustable bearing housing are slightly greater in diameter than said bolt means to accommodate slight radial movement of said adjustment bearing housings relative to said bolt means whereby the ends of said axle means are radially adjustable.
Claim 3
Dependent Claim
20 words
The valve of claim 1 wherein the disk face making sealing contact with a seat has a substantially spherical surface.
Claim 4
Dependent Claim
16 words
The valve of claim 1 wherein said axle means comprises a pair of opposed, aligned axles.
Claim 5
Dependent Claim
23 words
The valve of claim 3 wherein one of said axles is fixedly attached to a bearing housing adjustably secured to said valve body.
Claim 6
Dependent Claim
43 words
The valve of claim 3 wherein one of said axles passes through bearing means in a bearing housing secured to said valve body to a handle for rotating said axle means, said axle means transmitting rotational forces applied thereto to said valve disk.
Claim 7
Dependent Claim
