Abstract: A microhydraulic system includes a first hydraulically acting element as a master element with a master diaphragm, and a second hydraulically acting element as an actuator element with an actuator diaphragm. The master diaphragm is coupled fluidically to the actuator diaphragm such that deflection of the master diaphragm causes deflection of the actuator diaphragm and actuation of the master diaphragm, both via a compressive force and via a tensile force being provided. The master diaphragm, as a function of deflection of the master diaphragm, thus exerts a compressive or tensile force upon the actuator diaphragm.
