Abstract
An actuator () is connected, on one side, to a valve needle (), and on the opposite side, to a hydraulic piston () pertaining to a hydraulic length compensator. A working chamber () is divided by a tight separating membrane (), into an actuator chamber () containing the actuator () and a fluid chamber () which can be filled with the fluid to be dosed in a pressurized manner while the actuator chamber () and the hydraulic chamber () are filled with a hydraulic fluid. A base pressure can be produced in the hydraulic fluid by means of the pressure of the fluid to be dosed, which is transmitted through the separating membrane ().
