Abstract

Improvements introduced in a valve to respond to a pressure to distribute the fluid under pressure driven by a source of fluid to two user components one of which is preferably connected to an accumulator, whose valve includes a control valve that is arranged in a line which connects the fluid source with the first user component and which governs the passage section of said line, whose control valve has a control chamber and reduces the cross section of fluid passage while the control chamber communicates with the source of the fluid. Fluid and increases it while the control chamber communicates with a return line, and, in addition, that includes a pilot valve that modifies its position according to the pressure that exists in the line connecting the source of the fluid with the second user component, whose pilot valve establishes communication between the control chamber and the fluid source below a pressure of co predetermined munication, and connects the control chamber with the return line when the switching pressure is exceeded, characterized by the fact that the line (6, 6a) that connects the fluid source (2) with the second user component ( 7) can be closed by means of a stop valve (33, 11a) which closes when the control chamber (10) is in communication with the return line (12).
