Nozzle for bottle-filling machine - has sliding tube fixed to inner edge of elastic diaphragm acting as return spring

摘要

The nozzle fills bottles etc. from a tank, and has a filler tube moving axially in relation to the tank and connected to it, and into which the liquid flows from the tank. An axial rod acting as an air vent is fixed to the tank and extends inside the tube, being widened at the bottom to form a stop for the tube. The spout of an approaching bottle acts against a component connected to the tube so as to move the latter clear of the stop against spring action. Thebe (19) is fixed to the inner periphery of an elastic diaphragm (13), whose outer edge is secured to the tank, the diaphragm acting as the return spring.
