摘要： A fuel injection valve for an internal combustion engine, includes a valve element whose switched position depends at least indirectly on the switched state of a piezoelectric actuator that is acted on by a tubular, largely cylindrical prestressing device, which is manufactured out of a plate-shaped starting material and has at least two longitudinal edges that abut each other in such a way that the longitudinal rigidity is altered in this region. The prestressing device has at least one region whose longitudinal rigidity differs from that of a neighboring region and is situated in relation to the abutting longitudinal edges so as to reduce the bending moment that acts on the piezoelectric actuator and is generated by the altered longitudinal rigidity in the region of the abutting longitudinal edges.

摘要： A valve for controlling fluids for reservoir injection systems, includes a hydraulic coupler and a piezoelectric actuator. The hydraulic coupler includes a first piston, a second piston, and a coupler chamber disposed between the two pistons. The piezoelectric actuator is in communication with the first piston. The first piston is embodied as substantially cup-shaped, and the second piston is disposed in a recess in the first piston. The coupler chamber is disposed between the second piston and an inner bottom region of the first piston. As a result, a hydraulic coupler of compact design can be furnished without reversing the direction of motion of the two pistons.
