ABSTRACT:
A space-saving camshaft with at least one cam which can be deactivated includes a coupling bolt which slides back and forth transversely in the camshaft to connect and disconnect the cam and the camshaft. A compression spring in the camshaft urges the bolt toward a coupling bore in the cam in the absence of a countervailing force and the bolt can be forced out of the coupling bore by increasing the pressure of hydraulic fluid in an adjacent compartment in the cam to disconnect the cam from the camshaft.
