PROBLEM TO BE SOLVED: To improve efficiency of manufacturing or assembling work, to save an installation space and to avoid pulsation. SOLUTION: In this rotary valve type pump for a fluid intake/exhaust device having a plurality of intake ports and exhaust ports, chambers are integrally connected with both end parts of a cylinder, respectively. Cylindrical rotary valves are rotatably fitted into these chambers, respectively. A set of piston rods penetrating through each of the chambers or the rotary valves is connected with each of both side walls of a slide piston inside the cylinder. COPYRIGHT: (C)2006,JPO&NCIPI
