  • a filling head for individual and multiple-chamber counter-pressure filling machines receiving individual containers to hold material from a fluid supply and gas pressure source, further comprising: a filling material valve means having a passage therein alignable with a respective container, said probe being an electrical control probe mounted within a passageway formed in said valve means and capable of introduction into a container during filling unit operation for automatically regulating gas pressure source, fluid supply and relief in the passage of said valve means and controlled by the filling material in affecting fillingmachine operation, and said control means including means for introducing said probe to advance into the container engaged with the filling unit of the machine at the start of filling operation and means for retracting said probe from the filled container before removal from the filling unit of the machine at the termination of the filling operation.
  • a filling head according to claim 2 in which valve operating apparatus with said probe controls the opening and closing of said valve means, and a switch remote from said probe determines electrical energization operatively therewith.
  • a filling head according to claim 2 in which an electric proximity switch influenced selectively by gas pressure or fluid valve means triggers release from introducing said probe into the container.
  • a filling head in which a pneumatic stroke device and magnetic control valve for said device are provided in operative association with said probe, said magnetic control valve with said stroke device being actuated in response to triggering movement of said switch electrically energized upon opening movement of said fluid valve means.
  • a fluid valve body and a shaft portion are included with said valve means and extend in the range of said electric switch, said shaft portion forming a seat for said gas pressure valve means.
  • a filling head in which said probe is carried concentrically in a bore through the gas pressure and fluid valve means and is guided longitudinally moveable therein, the bore within the fluid valve shaft portion collectively forming loading and return gas path in range ofgas space of filled container, and a seal means against atmosphere surrounding preferably a free body end of gas pressure valve means.
  • a filling head which includes a return gas chamber communicating into an exhaust and a sleeve forming the return gas path, said sleeve being inserted inside the passage means of said valve body of the loading gas valve means and communicating with further passage means in said fluid valve shaft portion, said probe being in a bore within said sleeve from the upwardly open passage means to bottom of said valve body whereby a housing chamber is formed by way of a throttle member, controllable valve means and the like communicating selectively with atmosphere and container connection having pressure differential or relative to a filler container 10.
  • a filling head in which an intermediate member provides adjustable engagement with respect to the stroke and introducing movements of said stroke device and said probe for setting desired filling height in the engaged container.
  • a filling head in which means for actuating said proximity switch are provided for selectively making said probe effective and ineffective at least during introducing and retracting respectively with respect to the engaged fill container, and adjustable switch means provided to adapt sensitivity of said probe to conductivity of the particular fill material.
  • a filling head in which a pneumatic stroke device actuates said valve means at least in part, and a magnetic control valve affected by container engagement when container lift occurs is provided to effect energization of said electric switch.
  • a filling head in which said electric switch comprises a proximity switch affecting said magnetic control valve of said stroke device of said valve body for the loading gas valve of said valve means and a stroke cylinder influenced by said proximity switch is provided to effect lifting of the container into engaging relationship with the filling unit, there being a stroke member extension of said stroke cylinder having affect upon said electric switch, said extension being directly across from said electric switch upon engagement of the container with respect to the filling unit, and means'additionally having an overstroke of said stroke cylinder shifting said extension out of the range of said switch when a container is lacking.
  • a filling head in which a stepped throttling means including a magnetic control valve is effective upon a liquid valve means with respect to liquid feed, and a stroke device controlled by said magnetic control valve, said switch being a proximity switch effective whereby said magnetic control valve is actuated in response to opening of said liquid loading gas valve means.
  • a filling head in which an exhaust valve means is provided on an exit side branching by a passage into an under pressure generating canal and an inert gas source canal communicating with each other whereby both canals are separated from said exhaust passage, and a magnetic control valve including a valve portion closing said under pressure generating canal by way of a switch effective upon container engagement and including a further val've portion closing said inert gas source canal in response to actuation by said probe.
