Hydraulic camshaft adjuster having a locking pin for centre-locking provided for controlling a hydraulic medium
Abstract:
A hydraulic camshaft adjuster, including a rotor and a stator and a hydraulic medium management system, by which at least two chambers separated by a rotor-fixed vane can be or are connected to a hydraulic medium supply device and/or hydraulic medium discharge device by an interposed hydraulic valve, wherein the vane contains a switchable hydraulic medium control device designed for selective release and interruption of a fluid connection from one chamber to the other chamber. A locking device for excluding a rotational movement between the rotor and the stator locks the rotor to the stator in a vane position in which the volume of the two chambers is approximately equal, and includes a pin, interlockable with a stator-fixed component, designed to control the inflow and/or outflow of hydraulic medium to/from a chamber.
