As a device for signalling adjustment processes on an adjusting device which exhibits an actuator which is displaceable on a threaded section, a second threaded section is provided which has a measuring element the pitch of which is a multiple of the pitch of the actuator so that, when the actuator is adjusted, the measuring element is displaced by a multiple and the adjustment process becomes clearly recognisable. To transmit the longitudinal displacement, the measuring element can be coupled to a potentiometer which is located in the circuit of an indicating device reproducing the adjustment. However, this circuit can also be connected to a control device in which the detected longitudinal displacement can be processed as input variable. The device proposed can be used in adjusting devices for control systems, for example for controlling injection pumps. |
