Patent ID: 8752518

Claim:
Switchable device for supplying pressure to at least one load of an internal combustion engine, comprising: a cavity formed within a camshaft, a displacement element that is arranged in the cavity and that is displaceable between a first end position and a second end position, wherein the displacement element is provided with a pressure surface that at least partially borders, together with a wall of the cavity, a storage space that is connectable in a fluid-conducting manner to the load, and the storage space is connectable in a fluid-conducting manner to a pressure source, a force accumulator interacting with the displacement element, wherein the displacement element can be displaced through pressurization of the storage space against a force of the force accumulator from the first end position into the second end position, a locking mechanism for locking the displacement element in the second end position, a switch mechanism actuated by an actuator with a switch element that can be brought into at least first and second switch positions and interacts with the locking mechanism so that the locking of the displacement element in the first switch position is maintained and is released in the second switch position.
