Patent ID: 8201591

Claim:
An apparatus for batching powder and/or granular products comprising: a hopper for containing the powder and/or granular products; at least one passage, at a side thereof delimited by an element which is permeable to gas which element in turn communicates, with consent of control organs, alternatively with a first depression source and a first pressurized source, and at an opposite side thereof communicating with a discharge region of the powder and/or granular products into a corresponding container element; an obturator element acting in the passage in a substantially transversal direction with respect to a development of the passage, between an occluding position of the passage, in which a batching chamber is defined between the obturator element and the permeable element, and a position enabling transit of the powder and/or granular products towards the discharge region, the obturator element being conformed to place the hopper in functional communication with the batching chamber when in the occluding position, the first depression source, the first pressurized source and the obturator element being activated in a suitable reciprocal phase relation in which a batched quantity of the powder and/or granular products is loaded into the batching chamber and the following projection of the batched quantity along the passage and towards the discharge region; and, wherein the obturator element is activated by actuator organs of alternated motion parallel to a longitudinal development axis, the obturator element having a recess or an internal channel on an upper lateral surface thereof, in proximity of a head thereof, for placing the hopper in communication with the batching chamber when the obturator element is in the occluding position.
