Abstract

A hydraulic valve for a pivot motor adjustment device of a camshaft, the hydraulic valve including a valve housing with a longitudinal axis and a valve piston that is axially moveable in the valve housing along the longitudinal axis, wherein a first operating connection of the valve housing and a second operating connection of the valve housing is openable and closable by the valve piston, wherein the first operating connection and the second operating connection are axially offset from one another; and a supply connection of the valve housing, wherein the supply connection supplies the hydraulic valve with hydraulic fluid fed by a feed device, wherein the hydraulic fluid flows through the hydraulic valve on different paths defined by a flowable channel system of the valve piston.
