Abstract
PURPOSE: To put the power from the driving source to ample practical use in such a way that a relief pressure setting spring is moved in its noncompressed direction in proportion to the rise in the pressure of a discharge oil path of a multiple pump.
CONSTITUTION: When a multiple pump 3 is in nonload condition, a relief pressure setting spring 7 is compressed to its maximum by a spring 14, the relief pressure is set to be high pressure, and it can be put to ample practical use. When the multiple pump 3 becomes load condition, and a discharge oil path 5 begins to rise the pressure, at the same time as a piston 10 moves upward against the spring 14, a spring seat 9 moves a spring 7 in its noncompressed direction. Thus, the relief pressure is reduced, the spring 14 is closely brought into contact to stop the movement of the piston 10.
