ABSTRACT:
A filling element for filling machines, with the filling element having no filling tube and serving for filling bottles, cans, or similar containers with carbonated or non-carbonated liquids. The filling element includes a signal emitter for detecting the designated filling height in a container that is pressed onto the filling element and is to be filled. The signal emitter cooperates with a vertical bore that is disposed in the filling element coaxial to a container seal thereof, and is protected from the entry of liquid from the liquid guidance conduit of the filling element. The signal emitter is part of a measuring device which, when the designated filling height is detected, transmits a signal that triggers closing of the liquid flow valve of the filling element. The measuring device, in order to detect the designated filling height in a non-contact manner, is embodied to operate with pulses that are directed onto the surface of liquid in a pressed-on container, and are reflected from this liquid surface. The vertical bore has an end facing a pressed-on container, with the signal emitter being disposed above this end, i.e. on that side thereof remote from the container. The vertical bore serves not only for use by the signal emitter to react to the designated filling height, but also for use for the supply of gas to, and the withdrawal of gas from, a pressed-on container.
