Реферат: To avoid the customary outlay on sealing rings and the like and oil lubrication in the case of slide valves, one of the mutually opposite surfaces of the slide valve (16) and the slide valve housing (1) is hardened, at least in certain areas, and the other surface, in opposite areas, has dry-lubricating properties and is softer, with the result that sealing bearing areas for the slide valve (16) are formed there (Fig. 1). <IMAGE>
