Filling head for filling in a fluid into a filler neck of a tank

Abstract

A filling head 10 is described for filling in a liquid into a filler neck of a tank 14. To ensure highly reliable operation, a rotary connecting element 26 is provided to form a mechanical connection by rotating in relation to the filler neck of the tank 14. A rotatable operating part 30 serves to rotate the rotary connecting element 26. The operating part 30 is coupled to the rotary connecting element 26 by means of a torque-limiting coupling device 32 that, given a threshold torque, is triggered at least in one direction of rotation and decouples the rotatable operating part 30 from the rotary connecting element 26. A sensor is provided to detect the triggering of the torque-limiting coupling device 32 and to send a release signal for the established connection.
