Abstract (en)
[origin: US6315216B1] An injector having a multilayer piezoelectric actuator for injection systems, in particular for common rail diesel injection systems, of motor vehicles, in which the body of the piezoelectric actuator has a square or rectangular cross-sectional contour and is seated, together with a two-legged prestressing bracket that is mounted along opposed outer sides of the actuator body, inside a longitudinal bore of the injector body. The longitudinal bore has a polygonal cross-sectional shape with rounded corners, the shape is adapted to the cross-sectional contour of the actuator body and the prestressing bracket, so that outside the longitudinal bore, space is created in the injector body for a high-pressure bore located parallel to the longitudinal bore of the injector.
