Abstract: A valve clearance compensator for an internal combustion engine. The compensator includes a sliding member provided with a wedge-shaped surface. The sliding members are arranged so as to be axially displaceable between each control cam of a camshaft and an associated valve. The sliding member is acted upon in one direction constantly by a compression spring but acted upon in the other direction intermittently by an adjusting member. The adjusting member is connected with the camshaft and is adapted to displace the sliding member against the force of the compression spring when the associated valve is in a closed position and over a partial range of a closed period of the valve.

Abstract: This invention relates to an internal combustion engine, particularly to a diesel engine. The engine comprises a crankshaft, which is connected to each of a plurality of pistons by a connecting rod and a piston pin. Each connecting rod has two bearings for the piston pin and a crankpin of the crankshaft, respectively.

Abstract: This invention relates to an independent front axle suspension for passenger cars. The suspension possesses a lower guide member, which is set transversely to the longitudinal direction of the vehicle and is flexibly coupled to the vehicle body, and a shock absorber strut, or spring strut, which is located between this guide member and the vehicle body, on which strut a wheel carrier is retained.

Abstract: A process for cooling a passenger compartment of a vehicle equipped with a hydrogen-consuming engine by mechanical refrigeration involves compressing a gaseous coolant, condensing the resulting compressed and heated gaseous coolant with heat removal to liquefy the coolant, and evaporating the liquefied coolant under the action of a pressure relief valve so that the cold generated during the pressure relief is used to cool the passenger compartment. This process is improved by removing additional heat from the compressed coolant by passing the coolant through a metal hydride cooler.
