Abstract:
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.
