Pivotal connection for axis movable structures has cylindrical component whose fluid passages are connected to fluid connections of fluid dispensing head, which are arranged in different planes

摘要

The pivotal connection has cylindrical component (21) coaxially located within the tubular component (5). The tubular component has fluid connections (11,12), and the cylindrical component has fluid passages (25,27,28,31,33,34,49-54). Each fluid passage is connected to fluid connections and fluid connections (35,36,38,39) of a fluid dispensing head (37), which are arranged in different planes.
