Abstract
The filler spout comprises a tubular body having mounted therein a valve member and a magnetic actuator element connected to the valve member via a coupling member comprising two elements that are coupled to each other via a coupling that includes radial clearance.
Claims6
A filler spout comprising a tubular body having mounted therein a valve member extending over a valve seat, and a magnetic actuator element associated with a coil outside the body and connected to the valve member by an axial coupling member comprising a C-shaped yoke and a peg having a head separably engaged between branches of the yoke with a radial clearance.
A filler spout comprising a tubular body having mounted therein a valve member extending over a valve seat, and a magnetic actuator element associated with a coil outside the body and connected to the valve member by an axial coupling member comprising two separable elements coupled together with a radial clearance, and a secondary shutter disposed downstream from the valve member and rigidly connected thereto, the body having a constriction overlying the secondary shutter, the secondary shutter and the constriction being of dimensions and relative positioning that are appropriate to ensure that while the valve member is closed, the secondary shutter leaves a clearance relative to the constriction that is just sufficient to retain a liquid contained in the body between the valve member and the secondary shutter by means of capillarity.
