Abstract

A braking device for a valve controlled internal combustion engine for motor vehicles. Each cylinder has at least one exhaust valve, which is controllable for opening thereof by a camshaft having a main cam for moving operation and a supplementary cam which additionally becomes effective during braking operation. The supplementary cam is arranged in the plane of the main cam, and is capable of being lowered in the camshaft. The cam peak of the supplemental cam is arranged from 160.degree. to 200.degree. ahead of the main cam peak in the direction of rotation of the camshaft. The sides of the supplementary cam are embodied in such a way that upon reaching the upper dead center point, the exhaust valve associated therewith closes. The supplementary cam is capable of being actuated by a control shaft arranged in the rotational axis of the camshaft.
