<p>The invention relates to a dressing liquid filling unit, for vacuum packaging and the like machines. …<??>A problem currently encountered with conventional vacuum packaging machines is that these machines are usually excessively noisy and so constructed as to result in serious wear problems. …<??>The above technical problem is solved by a dressing liquid filling unit for vacuum packaging machines, comprising a valving member (2) for the introduction of dressing liquid, formed by a lower body (5) sealingly associable with a can (4) or the like, and an upper body (6) which is connected to the lower body (5) and pivotable relatively thereto to take a variety of operational positions. The rotation of the upper body (6) with respect to the lower one (5) is accomplished through a cam following element which is connected to a rod (30) extending axially from the upper body (6), which engages with a camming path correspondingly arranged along the processing path followed by cans (4) to be filled.</p> |
