Abstract
A filler spout including a tubular body having mounted therein a valve member extending facing a valve seat and a secondary shutter arranged in a distribution chamber downstream from the valve member and rigidly connected thereto with a small amount of axial clearance between the valve member and the secondary shutter, and a movable portion of an actuator being coupled to the valve member in order to move it between an extreme closure position and an extreme opening position. The valve member possesses an intermediate closure position and includes a portion that is received in a bore opening out into the distribution chamber in order to form a suction system when the valve member is moved from the extreme closure position to the intermediate closure position.
