• the cam causing the crank pin to move from its first position to its second position comprises an upper guide surface and a lower guide surface that are substantially parallel to one another so as to receive the crank pin between them, the upper surface being arranged to initiate the tilting of the crankpin to its second position and the lower surface being arranged to gradually slow the crankpin near its second position.
• the cams are movable between an active position in which they are on a trajectory of the crankpin and an inactive position in which the cams are clear of the trajectory of the crankpin.
• the installation can thus be used also without vertical displacement of the support member for filling containers with products that do not require the engagement of the filling spout in the neck. In in addition, this avoids mounting a container whose neck would be deformed and would not allow the insertion of the filling spout.
