Device to converting an electrical signal to a mechanical position

摘要

For a device for converting an electrical current signal into a mechanical control variable, consisting essentially of a pneumatic actuating element (1) with a push rod (2), a pneumatic amplifier (3), a compressed-air connection (4) and an electropneumatic signal converter which has an electromagnet (5), with a coil, an iron circuit and an air gap, a nozzle/baffle plate device (6) and a lever (8) which is supported on a clamping strip (7) such that it can pivot, it is proposed that one end of the clamping strip (7) be supported such that it can rotate about its longitudinal axis and that a return guidance lever (12) be arranged at right angles to the longitudinal axis, whose one end is connected in a rotationally fixed manner to the end of the clamping strip (7) which can rotate and whose free end is coupled to the push rod (2) of the pneumatic actuating element (1). ……
