Abstract (en)

[origin: EP2386731A1] The valve has a hollow piston with a piston bottom on which an actuator is applied. The piston is axially moved in the bush by the actuator against force of a screw-type pressure spring. A sleeve is provided in the piston and secured in the bush for movement relative to the piston. A wall of the sleeve includes a though-opening that leads to an opening of the piston. The opening leads a supply pressure that is applied inside the sleeve to two sets of pressure chambers (9, 10) of an oscillating-motor camshaft adjuster (14). A sleeve bottom of the sleeve closes an inner space of the piston.
