Abstract
Abstract High-temperature valves are difficult to seal, and careful sealing is necessary, particularly where the fluid being valved is inflammable or, for other reasons, leakage must be minimized or eliminated. In several species disclosed herein, leakage is minimized by a properly prepared and surface-treated valve stem, for maximum smoothness and minimum wear, together with seals of organic material having the requisite temperature resistance bearing thereagainst. In the preferred species, a bellows is secured between the valve body and the valve disc, with the valve stem limited to axial movement so complete sealing is effected. In a special case, the bellows is a synthetic polymer composition material with the bellows formed unitarily, on one end, with the synthetic polymer composition valve disc.

Claims Analysis
Total Claims: 26
Claim 1
Independent Claim
266 words
A fluid valve, said valve comprising: a. a body, an inlet passage and an outlet passage in said body for the flow of fluid therethrough, a seat in said body between said inlet and said outlet passages; b. a valve stem guide secured to said body, a valve stem reciprocably movable within and extending through said valve stem guide, a disc on said valve stem, said disc being movable into and out of engagement with respect to said seat in said body to selectively open and inhibit fluid passage between said inlet an outlet passages in said body; c. seal means engaged between said valve stem and said body to inhibit leakage between said valve stem and said body; and d. valve operator means connected to said valve stem to move said valve disc with respect to said seat, said valve operator means comprising: 1. a solenoid coil stationarily mounted with respect to said valve body, 2. a plunger movably mounted with respect to said solenoid coil so that electric energization of said solenoid coil urges said plunger with respect to said solenoid coil, 3. a lost-motion linkage connecting said plunger to said valve stem, said lost-motion linkage comprising a pin engaged in a hole, said hole being larger than said pin, the axes of said pin and said hole being substantially at right angles to the direction of movement of said valve stem, and 4. a flange secured to said valve stem, said hole being located in said flange, said plunger being bifurcated and embracing said flange, said pin being secured in said bifurcated plunger.
Claim 2
Dependent Claim
266 words
A fluid valve, said valve comprising: a. a body, an inlet passage and an outlet passage in said body for the flow of fluid therethrough, a seat in said body between said inlet and said outlet passages; b. a valve stem guide secured to said body, a valve stem reciprocably movable within and extending through said valve stem guide, a disc on said valve stem, said disc being movable into and out of engagement with respect to said seat in said body to selectively open and inhibit fluid passage between said inlet an outlet passages in said body; c. seal means engaged between said valve stem and said body to inhibit leakage between said valve stem and said body; and d. valve operator means connected to said valve stem to move said valve disc with respect to said seat, said valve operator means comprising: 1. a solenoid coil stationarily mounted with respect to said valve body, 2. a plunger movably mounted with respect to said solenoid coil so that electric energization of said solenoid coil urges said plunger with respect to said solenoid coil, 3. a lost-motion linkage connecting said plunger to said valve stem, said lost-motion linkage comprising a pin engaged in a hole, said hole being larger than said pin, the axes of said pin and said hole being substantially at right angles to the direction of movement of said valve stem, and 4. a flange secured to said valve stem, said hole being located in said flange, said plunger being bifurcated and embracing said flange, said pin being secured in said bifurcated plunger.
