Embodiment Construction

[0022] figure 1 A schematic diagram of a valve 100 according to an exemplary embodiment is shown. The valve 100 according to the illustrated exemplary embodiment is used as an inlet valve of a high-pressure pump 101 of a fuel delivery system for gasoline. Other uses of the valve 100 are also possible, for example as a volume flow control valve and / or as a pressure control valve.

[0023] The high-pressure pump 101 is especially designed to deliver fuel, such as petrol or diesel, from the fuel tank to the internal combustion engine of the motor vehicle. For example, fuel is injected into a combustion chamber of an internal combustion engine by means of injectors.

[0024] The valve 100 is designed, for example, to meter fluid into the delivery chamber 120 of the high-pressure pump 101 . When the valve 100 is open, it is possible for fluid to flow from the inlet 122 facing the fluid tank to the outlet 123 facing the delivery chamber 120 . The valve 100 can in particular also...

Abstract

The invention discloses a valve for a high-pressure pump for a motor vehicle, and the valve is provided with a first stop element having a longitudinal axis and a sealing seat; an actuator providing an actuator force so that the actuator can act along the longitudinal axis; a pin which can move relative to the first stop element along the longitudinal axis and move by the actuator force; a sealingelement moved by the pin relative to the valve seat in order to open or close the valve; and a second stop element rigidly fastened to the first stop element providing a stop for the sealing elementto limit movement of the sealing element away from the sealing seat along the longitudinal axis. The second stop element is fastened at a defined predetermined distance from the first stop element todefine a spacing between the sealing seat and the stop.

Description

technical field [0001] The present application relates to a valve for a high-pressure pump of a motor vehicle, in particular the present application relates to a valve for a pump for delivering fluid to an injection system of an internal combustion engine for a motor vehicle. Furthermore, the present application relates to a method for producing a valve, in particular a valve of the stated type, for a high-pressure pump of a motor vehicle. Background technique [0002] A fuel injection system for an internal combustion engine can have a high-pressure pump that delivers a fluid, in particular petrol or diesel, from a fluid tank to an injection valve of the internal combustion engine. In particular, tolerances may have an impact on the accuracy of the valve. [0003] It would be desirable to have a valve specified for a high pressure pump of a motor vehicle that is inexpensive and reliable. Furthermore, it would be desirable to specify a method for producing valves for high-...
