Abstract: A parking brake for a commercial vehicle equipped with an air-operated service brake is configured in such a way that the actuating energy for the brake is reduced in comparison to a configuration with a spring brake cylinder, while the installation space in the wheel area is minimized. Primary functional parts of the parking brake include an inner race and an outer race, which delimit an annular gap. Displaceable tapered-roller bearings are located in the annular gap. To adopt a release position in opposition to the action of a compression spring, the tapered roller bearings are disengaged from the conical surfaces of the inner race and the outer race.

Abstract: An intake filter for an internal combustion engine for a motor vehicle including an unfiltered air intake region, a filter medium and a filtered air conduit, in which the unfiltered air intake region is arranged beneath the engine hood of the motor vehicle and is attached to the engine hood. The filter medium is tubular body which has a porosity that ensures a sufficient filtration of the intake air for the internal combustion engine.

Abstract: The present invention relates to the arrangement of a stator and a spare stator. In order to avoid a permanent correction in the length of the driving shaft, the spare stator is connected to the instantaneously operated stator or is configured in a single piece. Upon occurrence of a defined amount of wear, this stator combination is merely reversed through 180° relative to the longitudinal axis or an intermediate tube is inserted so that the spare stator arrives in the rotor region.

Abstract: The invention is directed to a shaving foil for a shaving system of a shaving apparatus, in which the shaving foil cooperates with an undercutter adapted to be driven relative to the shaving foil. The shaving foil includes a perforate region comprised of a plurality of hair-receiving apertures, wherein said apertures form a quasi-periodic pattern executed in accordance with a Penrose parquet.

Abstract: A shaving system for a dry shaver has at least one long-hair cutter arranged between shaving units for short-hair cutting. The shaving units for short-hair cutting each include an upper blade and a lower blade, which can be moved relative to one another by a drive. The long-hair cutter is formed from at least two cutting elements that can be moved relative to one another and are arranged one beside the other. The cutting elements of the long-hair cutter are each of comb-like design, and their rows of cutting teeth, which are formed by tines, are oriented essentially perpendicularly to the skin which is to be shaved.
