<p>PROBLEM TO BE SOLVED: To shorten the size in the axial direction by deleting the flange of a plug sealing the releasing end of a cylinder. SOLUTION: The plural number of cylinders 2 are formed almost in the radial direction in a pump housing 1 so as to be disposed roughly at equal intervals in the circumferential direction. Each plunger 5 is mounted to the insides of the plural cylinders 2 so as to be freely slidable, and a pump chamber 7 is formed in the inside of each cylinder 2 the volume of which is expanded/ contracted by the slide movement of each plunger 5. A rotating shaft 10 provided with an eccentric cam 11 driving each plunger 5 is provided to the side to which the axial line of each plunger 5 is converged. A cover member 30 provided with each slice 33 is mounted to one side surface of the pump housing 1 which is in contact with each plug 3, and prevents each plug 3 from slipping out in the positioning direction and the radial direction.</p> |
