Abstract

PURPOSE: To reduce the cost through the reduction of the hydraulic unit capacity by providing a booster device between a rotary joint and a connecting hole.
CONSTITUTION: A primary pressure chamber 7 and a secondary pressure chamber 3 having a smaller cross-sectional area than said primary pressure chamber 7 are formed in that order between a rotary joint 12 and a connecting hole 2, said primary chamber 7 and secondary 3 being isolated each other by a booster piston 9 thereby enabling the supply of high pressure oil to the connecting hole 2 even when low pressure oil is introduced into the primary pressure chamber 7 for low pressure operation of the primary side, thus reducing the cost through the reduction of the hydraulic unit capacity.
