    摘要： 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.

    摘要： 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.

    摘要： A valve device includes a housing, a flow duct and a valve body. The valve body is arranged in the flow duct and bears with a sealing section against a housing-side sealing seat when the valve device is closed. The valve body is guided along a movement axis by a housing-side guide surface and bears with a stop surface against a housing-side movement limiting surface when the valve device is open to the maximum. The guide surface is provided by a guide element, and the sealing seat and the movement limiting surface are provided separately by the guide element.

    摘要： A method for producing a high-pressure fuel pump includes bringing a pump housing into contact with a lower electrode, gripping a pot-shaped cover element using a collet chuck, contacting the cover element with an electrode, bringing the open face of the cover element into contact with the face of the pump housing opposite the lower electrode, centering the cover element on the face of the pump housing opposite the lower electrode, pressing the cover element onto the pump housing in the direction of the lower electrode, and introducing an electrical current from the electrode via the cover element and the pump housing into the lower electrode, such that fusing occurs at the point of contact between the cover element and the pump housing, and such that subsequently the cover element is bonded to the pump housing. The pump housing and the cover element are connected by a peripheral weld seam.

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.
