摘要

Pressure limiting valve, in particular for limiting of the fluid pressure in a distributor pipe of a common - rail - injection system, comprisinga first housing part (30) with a through-bore with a first portion (42), which can be acted upon with the fluid pressure to be limited, a second portion (46) with respect to the of the first section of enlarged diameter and a between the first section and the second section designed valve seat (44),a displaceable along the second section, a total of rod-shaped valve member (48), which in the direction of the valve seat of a spring (70) is prestressed, so that a fluid passage between the first and the second section is blocked,a second housing part (40) with an additional through bore (62, 66, 68),wherein the first or second housing part has an external thread with an inner thread of the second or first housing part is screwed and the spring prestressing the valve member between the valve member and a stop provided in the additional through bore (64) is supported,characterized in that..
