Abstract: The invention relates to a pocket-type chain wheel (1) for link chains (22), in particular round or profile steel chains. A circumferential surface (2) of said pocket-type chain wheel is provided with pockets (3, 4) having alternately different shapes in the circumferential direction (U) and extending radially into the pocket-type chain wheel. In order to diminish noise generation in operation, reduce vibrations generated during operation and simultaneously cut production costs, the present invention discloses that the pocket-type chain wheel (1) is produced in one piece from a fiber-reinforced plastic by means of an injection molding process. Preferably, a main fiber direction (30) extends in a central area between the pockets (3, 4) and a hub (8) in the radial direction.

Abstract: A cylinder head gasket includes a metallic gasket layer having through-openings and, at its peripheral outer margin, a first sealing element for providing a seal. The first sealing element forms a sealing line extending circumferentially about the gasket layer and surrounding the through-openings. The side of the first sealing element facing away from the peripheral outer margin of the gasket layer includes a vent hole arranged adjacent to a sealing line break and located in a first gasket layer region which is, on only a first side of the gasket layer, on both sides of the sealing line break, continuously bounded by the first sealing element and a second sealing element. The first sealing element and the second sealing element extend around the first gasket layer region such that a fluid flow path extending from the sealing line break to the vent hole has at least one change in direction.
