摘要	PURPOSE: To reduce the internal leakage of a rotary pump to enhance the efficiency of pressure feed, by providing short cylindrical members having the same diameter as that of a ram section, at both sides of the latter, and by fitting these short cylindrical members in round hole sections in a rotor flange. CONSTITUTION: Short cylindrical sections 103c having the same diameter as that of a ram section 103, are provided at both sides of a movable block 103 in a rotary pump. These members 103c are fitted in round hole sections 102 formed in a rotor flange 102b. With this arrangement the end faces of the ram section 103b are prevented from being exposed to the end faces of the movable block 103, and therefore, when the ram section 103a is extended and retracted with respect to a fluid passage, it is possible to prevent the ram section 103 from sliding on the rotor flange.
