Abstract: A cylinder head cover for covering a cylinder head of an internal combustion engine having at least one first sealing surface via which the cylinder head cover can be tightly connected to an associated second sealing surface on the cylinder head, the cylinder head cover may include at least one first reference surface configured for unambiguous position-fixing on an associated second reference surface of the cylinder head. The at least one first reference surface and the at least one first sealing surface may be formed separately from one another.

Abstract: A fluid conduit coupling may include a tubular body, a connecting piece, and a securing clamp radially adjustable relative to the tubular body between a securing position and a release position. The connecting piece may have a securing groove extending in the circumferential direction, the tubular body may have a securing slot aligned radially to the securing groove when the connecting piece is inserted into the tubular body, and the securing clamp may have a securing web sticking out radially to the inside, and, in the securing position, radially engages with the securing groove through the securing slot, and, in the release position, does not radially engage with the securing groove. The tubular body may have at least one guide groove, and the securing clamp may have at least one guide web sticking out radially and, at least in the securing position, radially engages with the associated guide groove.

Abstract: A hose arrangement for a motor vehicle may include a flexible elongated bellows including a plurality of radially orientated pleats and two axial longitudinal ends. The hose arrangement may also include at least one reinforcement rib which, on an outside, is coupled to a pleat tip of a respective pleat of the plurality of pleats in a material-bonded manner via two-component injection moulding. The at least one reinforcement rib may engage about the respective pleat in a circumferential direction. The at least one reinforcement rib may have at least two rib segments disposed following one another in the circumferential direction. Each of the at least two rib segments may radially cover the pleat tip by a segment angle of 30° to 310° in the circumferential direction.

Abstract: A fluid conduit coupling for mechanically and fluidically coupling a fluid-conducting first component to a fluid-conducting second component, may include a tubular body, a connecting piece, which may be insertable coaxially into the tubular body, and a securing clamp, which may be arranged on an outside of the tubular body and which may surround the tubular body over more than 180° in a circumferential direction, and which may be radially adjustable relative to the tubular body between a securing position, in which the connecting piece cannot be pulled out of the tubular body, and a release position, in which the connecting piece is able to be pulled out of the tubular body.
