  • Method and device for indication of the position of hydraulically actuated armatures
    Patent number: 10302103
    Abstract: The invention relates to a method for indicating the position of a hydraulically actuated armature, having a piston (1.21) in a cylinder (1.2) for actuating the armature (1.1), which cylinder is connected by means of two hydraulic lines (2, 3) to a switch valve (7) through which the hydraulic lines can be switched between pressure-conducting feed flow and pressureless return flow, wherein the flow of the hydraulic fluid flowing through one of the hydraulic lines is converted into a number of electric pulses, each of which corresponds to a pre-determined unit of volume of the hydraulic fluid, the switch valve (7) is connected to supply lines (P, T), to which further switch valves (7) are connected for actuating further armatures (1.
