    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 method for operating a fuel system for an internal combustion engine having a metering device, an electrical actuating device, and a valve element includes: activating the electrical actuating device in at least one first cycle in such a way that the valve element switches into a second position corresponding to an open metering device; activating the electrical actuating device in at least one second cycle in such a way that the electrical actuating device is activated from activation to activation, with activation energy which decreases gradually, until a limiting case is reached in which the valve element only just or just no longer switches into the second position; ascertaining a first activation energy, which corresponds to the limiting case; and subsequently activating the actuating device, taking the first activation energy into account.

    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.

    Abstract: A piston-type fuel pump for an internal combustion engine includes a pump housing, a piston, an annular counterplate, and a non-return outlet valve. The pump housing includes a stepped opening and a piston opening. The piston is guided in the piston opening. The counterplate is pressed into the stepped opening and includes a valve seat. The non-return valve includes a valve element and a guide element. The guide element guides the valve element, is arranged radially outside the valve element and in the stepped opening, and includes a guide section, a retention section, and a support section. The guide section guides the valve element, the retention section is connected to the guide section via a radially extending connecting section, and the support section supports a valve spring. The sections are arranged axially at different points such that the guide section is between the counterplate and the support section.
