In a compressor particularly of an exhaust gas turbocharger of an internal combustion engine having a compressor wheel rotatably supported in a compressor housing which includes a diffuser structure with an adjustable diffuser geometry comprising guide vanes pivotally supported, an adjustment ring is provided with engagement elements which engage forked end structures of the guide vanes at the outer ends of the guide vanes opposite the pivotal guide vane support so that the pivot position of the guide vanes can be adjusted by rotation of the adjustment ring.

Compressor, particularly in an exhaust gas turbocharger for an internal combustion engine

In an exhaust-gas turbocharger having a compressor and an exhaust-gas turbine, which drives the compressor and comprises a multipart exhaust gas supply duct manifold and a turbine rotor, to which pressurized exhaust gas can be delivered by way of the exhaust gas supply duct, the exhaust gas supply duct manifold includes at least three flow passages, which, except for one, are provided with shut-off flaps, which are adjustable independently of one another.

Exhaust-gas turbocharger

A method for feeding sheets in a feeding direction along a guide face of a sheet guiding device in a sheet processing machine includes forming an air cushion between the guide face and a respective sheet by providing an air pressure distribution resulting in air flows beneath the respective sheet. The air pressure distribution is based virtually only on the effect of viscosity of the flowing air and is then capable of carrying the sheet; a device for performing the method; and a sheet processing machine such as a printing machine including the device.

Method and device for contact-free guidance of sheets

The invention relates to a radial compressor for producing a compressed gas flow, having a casing, an impeller which is arranged therein has a hub which carries blades. A ring is arranged in the flow duct concentrically with the hub, and is accommodated in a recess in the inner surface of the casing. The ring has wall slits on its inner surface. An annular gap is provided between that end face of the ring which is directed downstream and an end face of the recess which corresponds thereto and is directed upstream.

Radial compressor with wall slits

A hydrodynamic propulsion device possessing an expansion chamber located downstream of a cross-sectional widening for the inflow of a medium which is to be expelled through a discharge nozzle. The propulsion device is constructed as a static propulsion mechanism without movable components, in that the gaseous operating medium is produced in the propulsion device through the reaction of a hydrofuel, such as NaK with water.
