Fluid control valve esp. for fuel injection valves has system pressure section with pressure compensation unit corresponding with closing behavior of pressure maintenance valve

摘要

The valve has a closing member to regulate a fluid flow, which generates a system pressure within a system pressure section (21), to fill the hydraulic coupler. The section has a pressure compensation unit (23) corresponding with the closure behavior of a pressure maintenance valve (22). When there is a pressure drop, the compensation unit reduces the volume of the system pressure section. The compensation unit has an actuating member (29) charged by a pre-tension spring (28).
