Abstract

Zylindrischer Drehschieber (9,10) mit Abdichtung für Kolbenmotoren welcher, mindestens eine quer zu seiner Längsrichtung verlaufende Durchbrechung (12,12′) und zu jeder Seite derselben eine umlaufende Nut (18,19) für je einen Dichtungsring aufweist. An zumindest einer Stelle der Wand der den Drehschieber (9,10) aufnehmenden Bohrung ist mindestens eine Nut (18,19) vorgesehen, in deren jeder eine Dichtung angeordnet ist, die mit einer Stirnseite durch Federkraft gegen die Mantelfläche des Drehschiebers (9,10) anpreßbar ist. Die Durchbrechung (12,12′) verläuft diametral in einem vollwandigen Teil des Drehschiebers (9,10). Das Gas führt durch den Drehschieber (9, 10) diametral hindurch. Die in der Wand der den Drehschieber (9, 10) aufnehmenden Bohrung (14, 15) vorgesehene Nut (18,19) ist ringförmig. Es können auch mehrere konzentrische ringförmige Nuten vorgesehen sein, in deren jeder ein ringförmiger Dichtring (20,21) angeordnet ist. Cylindrical rotary valve (9,10) with seal for Piston engines which, at least one transverse to it Longitudinal opening (12,12 ') and to each side of it a circumferential groove (18,19) for each has a sealing ring. At least in one place Wall of the bore receiving the rotary valve (9, 10) at least one groove (18, 19) is provided, in each of which a seal is arranged with an end face Spring force against the outer surface of the rotary valve (9,10) can be pressed. The opening (12, 12 ') runs diametrically in a full-walled part of the rotary valve (9,10). The Gas leads diametrically through the rotary valve (9, 10). Those in the wall of the rotary valve (9, 10) Bore (14, 15) provided groove (18,19) is annular. It can also have several concentric annular grooves be provided, in each of which an annular sealing ring (20,21) is arranged.
