Pressure-limiting valve

A pressure limiting valve for placement in a return line of a common-rail-system of a combustion engine, the pressure limiting valve comprising:

• an elongate valve housing with an axial inlet opening present on one front side and connected by a housing passageway to at least one outlet opening axially separated from the inlet opening, a ball-shaped valve body located in the housing passageway engages with an interior valve seat that connects to the inlet opening and a valve piston is positioned within the housing passageway between the valve body and a closing spring that engages the valve piston producing a closing force, the outlet opening is positioned as a radial opening in a circumferential wall of the valve housing, and wherein the valve piston completely covers the outlet opening in a closed position and releases the outlet opening into an open position upon movement in a direction proceeding from the inlet opening, an integrated hydraulic throttle provided in the housing passageway and dampening movement of the valve piston in the valve closing direction, the hydraulic throttle is formed by a throttle section connecting to the valve seat on a side of the valve seat facing the valve piston, whereby the throttle section exhibits a cylindrical interior area with an interior diameter adapted to an exterior diameter of the valve body forming a circumferential throttle gap between the valve body and the interior area of the throttle section.
