Abstract: A steering wheel for a motor vehicle, particularly for a tractor. The steering wheel has spokes which engage the steering wheel rim and are connected directly or indirectly with the steering shaft. A stationary plate is arranged in, and is axially and/or radially spaced from, the steering wheel rim. The plate preferably serves for receiving or mounting indicator instruments. A dish-shaped part with an acute flank angle is arranged between the steering wheel spokes and the steering shaft as a transfer member for the rotary movements serving for steering. The dish-shaped part tapers toward the steering shaft and is rotatably journalled on a stationary vehicle part and is rigidly connected with a gear which meshes directly or indirectly with a gear seated or located secure against rotation on the steering shaft. Furthermore, the dish-shaped part serves to receive a holder for the stationary plate as well as for the instruments arranged on its backside.

The compressed air branched off from the compressor, or the gas under pressure, serves for direct drive of an energy exchanger which, while avoiding transmissions and the like, generates the oscillating or rotating movement necessary for driving the auxiliary apparatus of the gas turbine unit or the entire system formed therewith. The energy exchanger has working cylinder chambers, and the associated auxiliary apparatus, embodied as pumps, has displacement cylinder chambers, in which chambers pistons embodied in one piece or rigidly connected with each other are arranged axially movable.

Abstract: A plate-type filter lubricating oil or the like. The filter includes a cylindrical, rotatable filter element which is to be cleaned in closed condition by flow reversal along a portion of the filter surface. During the normal operation the entire filter surface is to be effectively available. The device includes a rinsing channel wall having a U-shaped profile, one leg of which constantly engages against the filter element and consequently serves as a wiper body during rotation of the element. To clean the filter element, both legs are pressed against the element, so that a rinsing channel results which communicates with a rinse-out opening and represents a back or return flow through the filter surface. A combination of two such filters provides an advantageous device for machines that are continuously operated.

The interior of the heat jacket is advantageously so designed, e.g. has a capillary design, that the liquid heat carrier in the heat jacket will also be able to flow against the force of gravity in the longitudinal direction of the cylinder bushing.

Abstract: A method and apparatus for operating an air-compressing, self-igniting combustion machine or engine, for liquid fuels, which has a combustion chamber depression, in the piston, into which fuel is sprayed or injected essentially centrally, preferably in a direction toward the depression wall, and in which the combustion air rotates at the time of injection. Oxygen-containing fuel that is reluctant to ignite is injected through an injection device into the combustion chamber depression, and an ignitible fuel is sprayed or injected through a second injection device, with an overlap in the injection times of the ignitible fuel and the oxygen-containing fuel that is reluctant to ignite. Ignition of the oil fuel, gas oil or Diesel fuel starts before injection of the oxygen-containing fuel that is reluctant to ignite. After approximately 2/3 of the injection time of the Diesel fuel, there begins the injection of the oxygen-containing fuel which is reluctant to ignite.
