Abstract: An internal combustion engine arranged in an automotive vehicle with optionally driven units or the like, for example, units driven by way of pulleys. The units extend toward a front if the internal combustion engine is arranged in a front compartment of the automotive vehicle and extend toward the rear beyond the internal combustion engine if the engine is disposed in a rear compartment. The units and optionally their drive elements are fashioned in such a way and/or are mounted to the internal combustion engine in such a manner that, in case of a collision, impact energy is absorbed at the units and/or their fasteners or mounting by the performance of deformation work, by overcoming frictional resistances, and/or by a displacement of viscous substances against a resistance.

Abstract: An adjustable drive for auxiliary aggregates of internal combustion engines in which some auxiliary aggregates such as the fan are adapted to be driven from the crankshaft of the internal combustion engine by way of an adjustable V-belt drive automatically regulatable under the influence of the centrifugal force in such a manner that at smaller crankshaft rotational speeds, a transmission with a speed-up results whereas at higher crankshaft rotational speeds a transmission with a speed reduction results; the control range of the V-belt drive is thereby subdivided at least into two partial ranges by a corresponding matching of the lever arms of the flyweights and/or of the spring forces, respectively, of the spring forces themselves, between which lies a range with constant transmission ratio.

A bundle of small tubes extending essentially in parallel to one another and movable relative to one another is arranged at least along a partial zone of a heat transfer path between the heat source and the heat sink. Each individual tube of the bundle of tubes is constructed in accordance with the heat pipe principle.

Abstract: An internal combustion engine operating with self-ignition which is equipped with a main combustion space including a piston recess and with an auxiliary chamber arranged in the cylinder head an injection nozzle is coordinated to the auxiliary chamber while the chamber includes an insert forming an overflow channel provided with several discharge holes terminating in the main combustion space.

Abstract: A side guard or lateral protection arrangement for motor vehicles, wherein at least one reinforcement, extending substantially in the longitudinal direction of the vehicle, is arranged within each of the side doors. The reinforcements are braced in case of a force effective in the longitudinal direction of the vehicle, with each end directly or indirectly against a component fixedly mounted to the vehicle or against a further reinforcement associated with an adjacent door. This bracing takes place in the longitudinal direction of the vehicle. The reinforcements are axially adjustable in their lengths so as to bridge a space between an end of the reinforcement means and the component fixedly mounted to the vehicle or further reinforcement, which space results from manufacturing tolerances in the construction of the motor vehicle.

Abstract: A cylinder lock which includes plate tumblers in a lock cylinder and a locking channel arranged in a lock casing wherein, when the key is pulled out (locked position of the lock), spring-loaded plate tumblers engage with their locking ends into the locking channel up to an extension length determined by locking stops. The lock casing is provided with an escape channel diametrically opposed to the locking channel for enabling a free resetting motion of the plate tumblers with their counter ends during an insertion of the key. The plate tumblers have, in their key cutouts, tumbler edges arranged at levels corresponding with an associated key cutout depth and, with a key being inserted (free position of the lock), can be reset into the lock cylinder. Stops are provided for limiting the resetting motion of the individual plate tumblers in the escape channel at insertion depths and a varying arrangement of the blocking stops is made in dependence upon a height of the respective tumbler edge.
