Abstract

A switch valve for controlling a hydraulic fluid flow, the switch valve comprising a tapping element that is arranged in a valve housing, wherein the tapping element 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 tapping element is limited, wherein the interlocking element is at least partially arranged in a recess of the tapping element, wherein the valve housing includes a first groove that is oriented in an axial direction of the valve housing and limited in the axial direction.
