Abstract
Die Erfindung betrifft ein Umschaltventil (11) zum Steuern eines Hydraulikflüssigkeitsstroms, mit einem in einem Ventilgehäuse (12) angeordneten Abgriffselement (13), welches wahlweise in eine erste Schaltstellung (S1) oder eine zweite Schaltstellung (S2) verlagerbar und mittels eines federelementbeaufschlagten Rastelementes (14) wahlweise in der ersten oder der zweiten Schaltstellung (S1, S2) arretierbar ist. In der ersten Schaltstellung (S1) ist ein erster Hydraulikanschluss (22) mit einem Entlastungsanschluss (26) und in der zweiten Schaltstellung (S2) ein zweiter Hydraulikanschluss (24) mit dem Entlastungsanschluss (26) verbunden, wobei ein Schaltweg des Abgriffselements (13) begrenzt vorgesehen ist. Das Ventilgehäuse (12) weist in einer axialen Richtung (L) eine axial begrenzte erste Nut (17) auf, in welcher das Rastelement (14) mit dem Abgriffselement (13) axial verschiebbar angeordnet ist. Das Rastelement (14) wirkt mit einem Rastpin (18) zusammen, welcher im Ventilgehäuse (12) im Bereich der ersten Nut (17) angeordnet ist.The invention relates to a changeover valve (11) for controlling a hydraulic fluid flow, having a tapping element (13) arranged in a valve housing (12), which is displaceable either into a first switching position (S1) or a second switching position (S2) and by means of a catch element (spring elementbeaufschlagten). 14) optionally in the first or the second switching position (S1, S2) can be locked. In the first switching position (S1), a first hydraulic connection (22) is connected to a discharge connection (26) and in the second switching position (S2) a second hydraulic connection (24) is connected to the discharge connection (26), wherein a switching path of the tapping element (13) is provided limited. The valve housing (12) has an axially limited first groove (17) in an axial direction (L), in which the latching element (14) with the tapping element (13) is arranged to be axially displaceable. The latching element (14) cooperates with a latching pin (18), which is arranged in the valve housing (12) in the region of the first groove (17).
Die Erfindung betrifft ferner einen Pleuel (1) mit einem Umschaltventil (11). The invention further relates to a connecting rod (1) with a switching valve (11).
