Abstract

A pressure-limiting valve for a fuel injection system includes a housing having a fluid inlet and a fluid outlet, a sealing seat, and a sealing body configured to move between a closed position in which the sealing body is in contact with the sealing seat, which blocks fluid flow from the fluid inlet to the fluid outlet, and additional positions that permit such fluid flow, and a holding device for keeping the sealing body in one of the additional positions if the sealing body is moved at least a specified distance away from the sealing seat.
