Abstract

PURPOSE: To enable optionally setting of operational characteristics of a hydraulic actuator unit by controlling sealed gas pressure in a back pressure chamber of a cylinder to thereby specify the dynamic value for operating the cylinder.
CONSTITUTION: A shoe 9 is oppositely provided in contact with a brake wheel 5 of a winding drum 2, and is held at the end of the piston rod 11 of a hydraulic cylinder 10 mounted in place at the buoy thereof. A rod 11 is urged by the gas pressure in a back pressure chamber 14 to be thus protruded on the ground, with the wheel 5 restricted by the shoe 9. When a buoy 1 is thrown to allow surrounding water to enter from an opening 13 into a dynamic chamber to thereby apply predetermined hydraulic pressure thereto, the piston is urged to release the brake on the drum 2, and a valve 16 is urged to escape the air or to charge the air from the valve 16 to thereby alter the operating pressure of the cylinder 10.
