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.

Abstract: A solid electrolytic capacitor is installed in a non-solderable aluminum housing by providing a solderable metal part which is welded to the base of the aluminum housing. Subsequently the capacitor is soldered to this metal part via a solder filler and thereby to the housing.

Abstract: A pressure-relief valve for an electrical capacitor which takes the form of a ring-shaped valve element of an elastic synthetic material which closes a valve opening in the housing of the capacitor. The valve member is held in position by a cylinder shaped part which has radial protuberances and which terminates in bulbous head. The bulbous head engages in snap-like fashion with a cooperable opening located in the housing of the capacitor. Suitable recesses are provided at the periphery of the cylindrical member to permit the valve to lift from its seat due to excess pressure within the capacitor.
