  • the stroke limitation assembly 900 manually operated at the part 910 located on the outside, makes it possible to adjust the size of the opening of the shutter 401, and therefore the start of the product, between a maximum value (absence of stop), an intermediate value (support of the stop surface 401c against the stop surface 925a), and a minimum value (support of the stop surface 401b against the stop surface 925a).
  • the choice of the size of the passage and of the flow rate, by lateral adjustment of the assembly 900, is made in particular as a function of the properties (size, shape, granularity and coefficient of friction, etc.) of the product to be distribute, so as to limit the flow of the products which flow most easily.
  • the level of the product in the main volume decreases, while the level of the product in the secondary volume remains maximum since the shutter 500 is closed.
  • the actual level of the product in the main volume can be observed at the level of the graduated window 308, and the operator can then choose, depending on this actual level, to replenish the main volume after removing the cover 700.
  • the drop in the level of product in the main volume as the distributions are made ends up releasing the shutter 500, so that it is the product located in the secondary volume which is then distributed.
  • This drop directly observable through the transparent wall formed by the front body 200, gives another type of indication for the need to refill the dispenser.
