Abstract: A multi-cylinder internal combustion engine with a valve shutoff. A mechanical device in which is integrated a valve clearance compensation arrangement, is interposed between an end of the valve stem and the valve actuating arrangement. A mechanical device includes a cup tappet and serves respectively arbitarily in one case as a rigid connecting member between the end of the valve stem and the valve actuating arrangement and, in the other case, during a closed position of the valve, eliminates the connection between the end of the valve stem and the valve actuating arrangement.

Abstract: A switching means for effecting a shutoff of valves of a multi-cylinder internal combustion engine wherein a servomechanism is provided which, upon a shutting off of the valves, acts upon an interposed energy storage arrangement in such a way that a spring-loaded leading mass of the energy storage arrangement, after a predetermined lead path, entrains an element connected with adjusting members for shutting off the valves.

Abstract: A method for operating a gas turbine installation and an apparatus for carrying out the method, particularly for a vehicle gas turbine installation, in which the air is compressed and heated up by utilizing the exhaust gas heat of the gas turbine installation, fuel is combusted under supply of compressed air with an excess of air, the resulting gas is thinned out and cooled off by admixture of compressed heated air, and the produced gas is then permitted to expand for producing an output; a more or less large quantity of non-preheated air is thereby admixed to the preheated primary air prior to the entry into the combustion zone at least within the lower partial load range, preferably as a function of load, in order to control the temperature in the combustion space.
