<p><P>PROBLEM TO BE SOLVED: To provide a compact pump gear device allowing easy access to individual cylinders and obtaining a short crank shaft. <P>SOLUTION: The pump gear device 10 is provided with a piston 13 functionally connected to a connecting rod 15 supported on a part 14 bent in a crank shape of the crank shaft 12 and includes a plurality of syringes 11 provided around the crank shaft 12 with each shaft thereof keeping a predetermined angle Wz. Each connecting rod 15 is supported on the unique part 14 bent in the crank shape. The part 14 bent in the crank shape keeps the predetermined angle shift Wk. The angle shift Wk is selected to keep the same phase displacement between two pistons 13 of the syringes 11 of which the cylinder shafts match with the angles Wz that cylinder shafts mutually have, and which are mutually continuously operated at the time of the rotation of the crank shaft 12. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
