ABSTRACT:
A controllable operating spindle includes a decompression cam mounted thereon, which cam is able to keep a valve actuation-movement transmitting element in a position which is spaced away from the position determined by a base circle of a cam on the engine camshaft. A ratchet wheel is connected to the operating spindle which extends along the length of and parallel to the engine camshaft and is adapted to co-act with a trip element for restoring the decompression cam to its original position. The operating spindle includes at least one decompression cam for each cylinder of the engine and between the decompression cam and the valve actuation-movement transmitting element there is provided a decompression lever which influences the transmitting element in accordance with the lift of the decompression cam.
