Abstract

PURPOSE: To reduce the size of an entire structure by making a coincident motion of a proportioning valve and a control valve by means of a free piston, thereby providing a smaller control spring.
CONSTITUTION: A proportioning valve P is worked according to a pressure of a spring 14 which depends on a motion of a deceleration speed sensitive valve G. An outlet pressure of the proportioning valve P is applied on a free piston 24, which operates on a poppet valve body 28 of a control valve K. An outlet pressure of the control valve K acts as an opposed pressure against the free piston 24 and a poppet valve body 9 of the proportioning valve P is opened or closed by the free piston so that the control valve K may operate with the proportioning valve P to control a liquid pressure in the second system. Because the proportioning valve P has only to control a liquid pressure in one system only, a large spring 14 is not required, thereby reducing the size of an entire structure.
