Abstract

L'invention concerne un distributeur (1) de produits pâteux (M), constitué d'un espace de stockage (2) pourvu d'une partie de délimitation (5) entraînée en déplacement lors de l'aspiration depuis l'espace de stockage (2) et d'une pièce de tête (4) guidée par rapport à l'espace de stockage (2). Une chambre de distribution (19) est réalisée entre la pièce de tête (4) et l'espace de stockage (2) et comprend une soupape d'entrée (43) et une soupape de sortie (41). Un canal de distribution (23) pourvu d'un orifice de distribution (24) est associé à la chambre de distribution (19). L'invention prévoit pour le retour élastique de la pièce de tête (4) dans le cas d'un déplacement depuis une position de départ dans une position d'actionnement un élément de ressort (22) agissant entre l'espace de stockage (2) et la pièce de tête (4), lequel forme dans le même temps en partie une paroi de délimitation (29) de la chambre de distribution (19) et comporte une partie faisant saillie enfichable inférieure (38) en forme d'oreille et une partie moulée saillante de maintien supérieure. Par ailleurs, lorsque l'élément de ressort (22) est réalisé en une partie avec la partie faisant saillie de maintien (30) et la partie faisant saillie enfichable (38) par rapport à ladite section transversale dans la position de départ, l'élément de ressort (22) est réalisé sous la forme d'une branche (26) s'étendant dans le prolongement de la partie faisant saillie enfichable (38), qui devient la partie faisant saillie de maintien par l'intermédiaire d'une incurvation (27) dirigée vers le haut. L'invention vise à améliorer la conception d'un distributeur du type susmentionné sur le plan fonctionnel et en matière de montage avantageux. L'invention propose à cet effet que la partie moulée de maintien saillante soit réalisée sous la forme d'une partie faisant saillie de maintien (30) dont la section transversale est plus grande que la branche (26) et qui comprend un socle supérieur (35) de partie faisant saillie situé dans le logement de maintien, qui comporte une section transversale fermée.
