ABSTRACT:
A valve assembly for a bottling machine composed of a mechanical unit and a pneumatic assembly mounted on a single support. The mechanical assembly includes a bottle centerer which places the neck of a bottle in a suitable position in relation to the centerer and which is displaced vertically by the bottle to act on an activating valve of the pneumatic assembly to activate a pneumatic cylinder. The piston of the cylinder moves downwards and draws with it a tubular air duct to which is attached a nozzle, which moves inside a coaxial tubular channel member defining an intermediate space for the passage of liquid. The liquid is discharged at the end of the channel member, when the nozzle is in extended position to fill the bottle whereupon the liquid blocks the nozzle and prevents the exit of compressed air from the duct at a low pressure and rate. The pneumatic assembly detects this condition and reverses the cylinder, so that the air duct is retracted and the nozzle blocks the outlet of liquid from the channel member.
