Abstract

La présente invention concerne un distributeur à tiroir cylindrique comprenant : un corps de distributeur principal (11) avec un trou de chargement prévu dans celui-ci; un corps de distributeur auxiliaire (2) qui est directement ou indirectement accouplé au corps de distributeur principal (11); un dispositif d'entraînement (1) présentant une extrémité de sortie d'énergie; un corps entraîné (8) qui est situé entre le corps de distributeur principal (11) et le corps de distributeur auxiliaire (2), un trou de montage étant prévu dans le corps entraîné (8); une plaque de distributeur (9) qui est montée dans le trou de montage du corps entraîné (8) d'une manière axialement mobile et bloque le trou de montage; et un corps de trou traversant (6) qui est monté dans le corps entraîné (8) et/ou dans un trou de montage du corps de distributeur principal (11) d'une manière axialement mobile. Un trou traversant et un élastomère (7) sont prévus sur le corps de trou traversant (6), l'élastomère étant monté dans le trou de montage du corps de distributeur principal (11) et/ou dans le trou de chargement du corps de distributeur principal (11). Le corps entraîné (8) est raccordé directement ou indirectement à l'extrémité de sortie d'énergie du dispositif d'entraînement (1) et peut être entraîné par le dispositif d'entraînement (1) pour effectuer un mouvement de va-et-vient de façon à ouvrir ou fermer le trou de chargement dans le corps de distributeur principal (11). La présente invention concerne également une pompe de distribution comprenant le distributeur à tiroir cylindrique.
