Description

Gegenstand des Patents 862 562 ist eine Umsteuerung für Kolbenmaschinen, bei denen die Kolben in den Endstellungen einen am Verdrehen verhinderten, mit einer Einlaßnut für das Druckmittel versehenen Hilfsschielber verschieben, der Ringnuten für den Austritt des verbrauchten Druckmittels aufweist, weil dadurch erreicht wird, daß an den beiden Stirnflächen des Hilfsschiebers stets die gleichen Drücke herrschen, was nicht der Fall ist, wenn die Ausströmungen an den Stirnflächen des Hilfsschiebers erfolgen. An sich bekannt ist es auch, radiale oder winklig zueinander stehende Bohrungen oder Schrägnuten in Schieberiff anzuordnen. Gegenstand der Erfindung ist nicht die Anordnung dieser an sich bekannten radialen Bohrungen oder Schrägnuten in einem Schieber, sondern ihreVerwendung für den Austritt des verbrauchten Druckmittels bei dem Gegenstand des Patents 862562. The subject of patent 862 562 is a reversal for piston machines, in which the pistons in the end positions move an auxiliary switch, which is prevented from rotating and is provided with an inlet groove for the pressure medium and which has annular grooves for the outlet of the used pressure medium, because this means that at the two end faces of the auxiliary slide always have the same pressures, which is not the case when the outflows take place at the end faces of the auxiliary slide. It is also known per se to arrange bores or inclined grooves in the sliding reef that are radial or at an angle to one another. The subject of the invention is not the arrangement of these known radial bores or inclined grooves in a slide, but their use for the exit of the used pressure medium in the subject of the patent 862562.

In Abb. t ist der Hilfsschieber f mit den bekannten Ringnuten s und s1 dargestellt, die zur Ausströmung des verbrauchten Druckmittels für den Umsbeuerschieber dienen, während die Nut n zur Einströmung des Druckmittels dient und mit Hilfe der Nut o und der in diese eingreifenden Schraube p die Verdrehung des Hilfsschiebers f verhindert wird. In Abb. 2 -sind die Ringnuten des Hilfsschiebers f durch radiale Bohrungen z und z1 für die Ausströmung des verbrauchten Druckmittels ersetzt, während Abb. 3 Schrägnuten y und y1 zeigt, die zur Ausströmung dienen, wenn die Ausströmöffnungen winklig zur Einströmöffnung liegen.In Fig. T is the auxiliary slide f with the well-known ring grooves s and shown s1, the outflow of the used pressure medium for the Umsbeuerschieber serve, while the groove n is used for the inflow of the pressure medium and with the help of Groove o and the screw p engaging in this the rotation of the auxiliary slide f is prevented. In Fig. 2 - the annular grooves of the auxiliary slide f are radial Bores z and z1 for the outflow of the used pressure medium replaced while Fig. 3 shows inclined grooves y and y1, which are used for outflow when the outflow openings lie at an angle to the inlet opening.

Statt Schrägnuten können auch an sich ebenfalls bekannte winklig zueinander stehende Bohrungen im Hilfsschieber angeordnet werden. -Instead of inclined grooves, also known angled to one another can also be used standing holes are arranged in the auxiliary slide. -
