Abstract
PURPOSE: To achieve reduction of energy consumption by providing PC mechanism with a simple lever mechanism so that all the sections within the PC mechanism's characteristics curve are satisfied and wasting of surplus discharging capacity of a hydraulic pump is eliminated.
CONSTITUTION: A piston 2 is pushed to the left by pressurized fluid of a hydraulic pump flowing into a pressurizing chamber 3 of a PC mechanism 16 and stopped at an appropriate position matched with compression of a spring 5. As long as a bottom lever 7 is in contact with a piston's projected end 2a, this tilting mechanism 2 takes an inclined position on a characteristics curve. When it is necessary to take a given angle of inclination in the characteristics curve, by operating a top lever 9 to the left, the piston's projected end 2a and the bottom lever 7 part from each other, and the hydraulic pump takes an inclined position parting the characteristics curve. And if the top lever 9 is operated to the right, after the bottom lever 7 contacts the projected end 2a, only the lever 9 is to become rotated.
