    Abstract: A valve device includes a housing, a flow duct and a valve body. The valve body is arranged in the flow duct and has a sealing section that bears against a housing-side sealing seat when the valve device is closed. The sealing section and the sealing seat together form a sealing region. There is a collapse zone immediately upstream of the sealing region in the flow duct when the valve device is closed. The collapse zone is delimited by a boundary wall that is at least substantially perpendicular with respect to a movement axis of the valve body and by a deflector wall that is arranged at an angle with respect to the boundary wall. The boundary wall is longer than the deflector wall.

    Abstract: A piston fuel pump for an internal combustion engine includes a pump housing, a piston, and a non-return discharge valve. The non-return discharge valve has a valve element and a guide element configured to guide the movement of the valve element. The guide element is at least indirectly pressed in a radial manner into an opening in the pump housing.

    Abstract: A fuel injection system for high-pressure injection in internal combustion engines includes: a fuel distributor; and at least one holder which is used for fastening the fuel distributor to an add-on structure. The holder includes a holder body which has a first layer, a second layer, and an elastically deformable damping layer. The first layer and the second layer are made from a metallic material. The elastically deformable damping layer is disposed between the first layer and the second layer. The holder body is connected to the fuel distributor by laser welding. The damping layer is made of a visco-elastic material.

    Abstract: A quantity control valve comprises a valve needle configured to move in an axial direction, a damping chamber having a wall, and a valve element delimiting the damping chamber. The valve needle is configured to move the valve element in an opening direction. A gap is defined between the wall of the damping chamber and the valve element. The gap has at least one recess and connects the damping chamber to a flow duct.

    Abstract: A system, which in particular is used as a fuel injection system for high-pressure injection in internal combustion engines, includes a fuel distributor and a plurality of fuel injectors. Each of the fuel injectors is situated on a cup of the fuel distributor. At least one of the fuel injectors is fastened to the associated cup by a retaining clip. The retaining clip has at least one clip section which is situated between an inner side of the cup and an outer side of the fuel injector. Furthermore, at least one damping composite element is provided, which is situated between the clip section of the retaining clip and the outer side of the fuel injector. The damping composite element has an elastically deformable damping layer. A decoupling is thus realized, which acts to damp vibrations and consequently to reduce noise.
