Abstract
A variable displacement radial piston pump includes a plurality of pump sections which are grouped into two. A first group of pump sections are communicable through a first discharge passage with a third discharge passage. A second group of pump sections are communicable through a second discharge passage with the third discharge passage. A control valve is provided for selectively supplying discharge from said first and second groups of pump sections to the third discharge passage and thereby stepwisely varying the discharge through the third discharge passage.
