Hydraulic Valve and Piston Rod with Hydraulic Valve

摘要

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.
