摘要： A valve for controlling fluids, in particular in an injection valve of an internal combustion engine, including a valve housing (20), in which housing a system region (21) is embodied, in which region a piezoelectric actuator module (22) and a hydraulic coupler module (23) are disposed, which has both an adjusting piston (24), on which the actuator module (22) acts, and an actuating piston (30) that is operatively connected via a hydraulic chamber (29) to the adjusting piston (24) and that is connected to a valve closing member (31) cooperating with a valve seat (37), and the adjusting piston (24) and the actuating piston (30) define the hydraulic chamber (29), and a system pressure for refilling the hydraulic chamber (29) prevails in the system region (21), from which a diversion conduit (38) branches off. The system region (21) is acted upon by a fluid via the diversion conduit (38).

摘要： A fuel injection system for internal combustion engines having a plurality of fuel injectors, in which the fuel injectors each have one high-pressure connection and one low-pressure connection, and the low-pressure connections discharge into at least one manifold line. The system has a means, located between the manifold line and a pressureless fuel return, for maintaining the fuel pressure; at least one throttle is located between the low-pressure connection of each fuel injector and the means for maintaining the fuel pressure.

摘要： A pressure-holding valve for a fuel injection system with a high-pressure region and a low-pressure region, the valve having with a valve housing having a first connection that can be connected to the low-pressure region and a second connection that can be connected to the return of a fuel injection valve device. The housing contains a reciprocating valve cup prestressed in opposition to the force of a first spring device and a through opening which can be closed by a closing element prestressed in opposition to the force of a second spring device to maintain a minimum pressure in the return. The valve housing, between the first connection and the valve cup includes with a pressure relief device that can be actuated from outside the housing.
