PROBLEM TO BE SOLVED: To regulate a delivering rate of a pump simply by providing a suction regulating valve which is acted with a flow-in passage directly, in a suction regulating pump having volume displacement bodies for delivering a medium, and arranging the valve on an end part of the suction chamber side of the flow-in passage. SOLUTION: A radial piston pump is provided with volume displacement bodies 5(5a, 5b) housed in a cylinder block 3, and each volume displacement body 5 is housed in holes 9a, 9b extending in a radial direction of a driving shaft 7. Each volume displacement body 5 is formed in a cup shape, and is energized inward in a radial direction by a coil spring 13 housed in its inner chamber, and perform reciprocating motion by rotation of an eccentric wheel 19 arranged on the driving shaft 7. A medium sucked in delivery chambers 17a, 17b by the reciprocation motion is boosted up and delivered. In this case, a suction regulating valve 33 including an annular valve element 35 is interposed in each flow-in passage 25(25a, 25b), and all flow-in passages 25 connected to a suction chamber 27 are regulated. |
