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.

Switch valve for controlling a hydraulic fluid flow and connecting rod with the switch valve

A hydraulic valve, in particular for shifting an actuation piston in a piston rod for an internal combustion engine with variable compression, the piston rod including a valve housing which includes a first operating connection and a second operating connection and a supply connection which is loadable with a hydraulic pressure of a hydraulic fluid, wherein a piston that is movably arranged in the valve housing is movable in a linear manner against a force of a preloaded spring, wherein the operating connections and the supply connection are sealable relative to each other and against an ambient atmosphere by seal elements upon correct installation in a valve receiving bore hole of the connecting rod, and wherein the seal elements are applicable against a wall of the valve receiving bore hole in a sealing manner due to the hydraulic pressure.

Hydraulic valve and piston rod with hydraulic valve

A connecting rod for a two stage variable compression in an internal combustion engine, the connecting rod including a combustion piston pin support eye that is arranged offset relative to an axis in an eccentrical component which is pivotable about the axis in a first direction of rotation through a first hydraulic displacement cavity and pivotable in a second direction of rotation through a second hydraulic displacement cavity, wherein a hydraulic valve is arranged in the connecting rod, wherein the hydraulic valve includes a hydraulic supply connection at which a hydraulic pressure is applied, wherein the hydraulic pressure moves a hydraulic piston against a force of a preload of a spring, wherein the hydraulic piston remains in a stable low pressure position in a low range of the hydraulic pressure due to the preload of the spring.
