摘要

The distributor has a central spindle (3) fitted with parallel channels (9) allowing the inlet or exhaust of the hydraulic fluid. A number of holes (10) in the spindle connect with the main channels. The spindle also has grooves (11) which take 'O' rings to seal one section of the spindle from another. The spindle is actuated from the ficing holes (12). At either end and the spindle is positioned by the end cams (13) for the lugs (7). The housing has corresponding outlet and inlet connections for the hydraulic fluid and fixing holes (6).
