Gas valve designed as a Kohl slide valve

The invention relates to a gas valve designed as a hollow slide, in particular a blow valve for high-voltage pressure gas valve, with a mechanically operated slide valve, that by means of two edge deserts, which have sliding seals, in a cylinder are slidably mounted.

It has become known a drive with a Drucicnittel a hollow slider for pneumatically operated high voltage switch sur impingement, wherein: the movable Schiebe'organ to ά & η r.nden Ranawülste own and u ± i which there rt-gefur in a cylinder xst. For sealing purposes, gaskets in --orr: elastic O-rings are housed in the edge vaults, with metallic hangings arranged (DT-AS 1 130 o57). In this version, the sliding element overflows the elastic sealing rings over the ceffr.n-ger to be controlled. i-cylinder, sas in terms of a desired

long-lasting preservation of the functional capability of the seal rings has a disadvantageous effect, as the games d r sealing rings, which run over the openings in the cylinder are subject to increased wear. The metallic rings associated with the elastic sealing rings for additional sealing can naturally π «?" Fulfill a minor sealing function »

The invention is based on the object of specifying a solution in the case of hollow slides of the type mentioned at the beginning, in which a substantial increase in the service life for sliding loss problems is achieved by avoiding the passage of openings at all. According to the invention, this is achieved by the fact that the hand beads have different diameters, with which they are each stored in cylinder beads corresponding to the diameter, and that a hollow space formed by the cylinder part with a larger diameter is arranged in the two circumferential beads. An intermediate ring covering the openings when the slide is closed is provided _a which is slidably mounted in the cylinder part of the larger Burchnesser uiid whose inner diameter is the same as the inner diameter of the cylinder part of the smaller diameter ₃ whereby this intermediate ring has a stop through which after a Texlöffnungshub the slide member ₃ as soon as this with its bead smaller Diameter has accumulated on the intermediate ring, the latter is carried along.

For this purpose, the elastic sealing rings 5a and 3b are arranged in corresponding annular grooves of the edge beads 2a, 2b. In a ring-shaped cavity there is the intermediate ring 5, which is slidably mounted in the 2 cylinder part 1 a and is under the action of the spring 6, which gently pushes it towards the right.
