Abstract

L'invention concerne un distributeur (1) pour la distribution de masses (M) fluides, par exemple liquides ou pâteuses, doté d'un récipient de réserve (2) pour la réception de la masse (M), comprenant une pompe de distributeur (6), le distributeur (1) présentant un axe longitudinal (x), la pompe de distributeur (6) présentant en outre un canal d'entrée et un canal de sortie (12, 13) et une chambre de pompe (11) délimitée par des soupapes (14, 15) du côté entré du côté sortie ainsi qu'une tête (5), la tête (5) présentant un orifice de distribution (23), une partie servant de pompe (P) étant déplaçable par rapport à une partie de cuve (9) contre une force élastique d'un dispositif de rappel (16), pour l'obtention d'un coup de pompe (b) et la tête (5) étant accouplée en mouvement à la partie servant de pompe (P), de sorte qu'un mouvement de la tête (5) d'une position complètement enfoncée à une hauteur de sortie atteignable correspond à un coup de pompe (b). Afin de créer un distributeur en outre amélioré en termes de polyvalence, il est proposé qu'un dispositif de limitation (27) modifiable pour la limitation modifiable du coup de pompe (b) soit prévu et qu'une modification du coup de pompe (b) corresponde à une modification de la hauteur de sortie.
