FILLING NOZZLE FOR FILLING MACHINES, IN PARTICULAR FILLING PONDERAL MACHINES, OF CONTAINERS SUCH AS DRUMS, BOTTLES, CANS AND/OR SIMILAR

摘要

The present invention concerns a filling nozzle (1) for filling machines, in particular weight-grading machines, for containers such as drums, bottles, cans and/or the like, comprising: a hollow body (2) defining an inner channel (3) for the transit of a fluid (4), the hollow body (2) being provided with at least one supply duct (6) of the fluid (4) and a dispensing opening (7) of the fluid (4) coming from the supply duct (6); a valve member (8) operatively associated with the dispensing opening (7) of the hollow body (2), being switchable between a first condition, wherein it sealingly obstructs the dispensing opening (7) of the hollow body (2) to prevent the fluid (4) outflow through the latter and a second condition, wherein it disengages the dispensing opening (7) of the hollow body (2) to allow the fluid (4) outflow from the latter. The nozzle (1) further comprises a piston (9) operatively engaged in the inner channel (3) defined by the hollow body (2). The piston (9) is controllable as for movement and/or switching for isolating the dispensing opening (7) of the hollow body (2) with respect to the supply duct (6) of the fluid (4) and for determining the controlled outflow, from the dispensing opening (7) of the hollow body (2), of the fluid (4) present between the latter and the piston (9).
