Abstract
Abstract A slide valve in which the slide is supported in the valve chamber on links interengaged between the ends of the slide and the body, the body and slide having fluid passages, and the body passages having tubular seals having face-to-face sealing engagement with the slide. The slide is actuated by a lever extending through a wall of the body and engaged with the slide between its ends.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
168 words
A control valve comprising a body having top, bottom and side walls and ends forming a closed chamber, a slide disposed in said chamber, inlet and outlet ports providing inlet and outlet passage means in said walls, said slide having ports providing passage means for conducting fluid between said ports, sealing means interposed between said body and said slide including tubular seal elements circumscribing certain of said ports and having end faces sealingly engaged with opposing faces through which other ports open for controlling the flow of fluid through said passage means upon shifting of said slide in said chamber, said seal elements each having its other end exposed to pressure of fluid in its port to force the end face of said sealing element into engagement with said opposing face, pivot link means interengaged with said slide and said body supporting said slide in said chamber in spaced relation to said walls of said body for movement of said slide, and actuator means for shifting said slide.
Claim 2
Dependent Claim
