Abstract

A switch valve for controlling a hydraulic fluid flow, the switch valve comprising: a capture element that is arranged in a valve housing and that is displaceable into a first switching position or a second switching position and interlockable by a spring loaded interlocking element in the first switching position or the second switching position, wherein a first hydraulic connection is connected with a relief connection in the first switching position and a second hydraulic connection is connected with the relief connection in the second switching position, wherein a switching travel of the capture element is limited, wherein the interlocking element is at least partially arranged in a recess of the capture element, and wherein the valve housing includes a first groove that is oriented in an axial direction and limited in the axial direction wherein the interlocking element is arranged axially movable in the first groove.
