Abstract
PURPOSE: To bring the distribution of liquid pressure close to an ideal level by controlling the liquid pressure at the first and the second limit points with a G valve or the like in one of two systems and then, the liquid pressure in the other system is controlled in relation with said control.
CONSTITUTION: In the system A, a liquid pressure of an input liquid chamber a2 is transmitted to an output liquid chamber a2 via a path 11 and the pressure of the input and output liquids rises at the same level. When a G valve is closed, the output liquid pressure is controlled in a slow rise at a fixed level determined by the diameter ratio between pistons 4 and 5 and reaches the first break point. When the pistons 4 and 5 hit a stopper 2 with increase in the input liquid pressure, the output liquid pressure stops in the rise reaching the second break point. In the system B, pistons 15 and 18 are kept from moving because of balanced pressure before the input liquid pressure reaches the first break point in the system A and in stead, the pressure of input and output liquids rises at the same level. However, when it exceeds the first limit point, the difference in the pressure in caused to move a piston 18 to the right closing a valve mechanism resulting in a slow rise in the output liquid pressure. Thereafter, the piston 18 serves to balance the liquid pressure in the systems A and B and the control. is performed at the first and second limit points as it is done in the system A.
