Abstract
PURPOSE: To render the entire structure of a flow distributing valve compact and light and also to lower the manufacturing costs, by connecting an outlet passage of the first pump and that of a second pump to each other by the intermediary of a check valve.
CONSTITUTION: In a system for supplying fluid to the first load 21 at a constant rate by use of a single spool when the pump speed is higher than a certain value, outlet passages 19a and 20a respectively of the first pump 19 and the second pump 20 are connected with each other by the intermediary of check valve 23. Since, with such an arrangement, the number of ports for a flow distributing valve can be made four, the entire structure of the flow distributing valve can be rendered compact and light. Further, since the number of variable restriction valves can be made three, the manufacturing costs can be lowered.
