<p><P>PROBLEM TO BE SOLVED: To improve versatility by allowing to attach/detach discharge parts to/from a base body and use only a desired number of the discharge parts. <P>SOLUTION: This grease pump device is equipped with: the base body 1 including a storage chamber 2 for storing grease, and a communication port part 4 communicated with the storage chamber 2; and the discharge part 10 communicated with the storage chamber 2 of the base body 1 and including a suction port 11 for sucking the grease, a discharge port 12 for discharging the grease, and a discharge part body 14 including a cylinder chamber 13 for storing the sucked grease; a piston 20 advanceably/retreatably provided with respect to the cylinder chamber 13 of the discharge part 10 for making the grease in the cylinder chamber 13 to be discharged from the discharge port 12 when advancing by pushing out the grease, and making the grease in the storage chamber 2 to be sucked from the suction port 11 when retreating; and a drive part 30 for advancing/retreating the piston 20. A blocking body 40 is made attachable equipped with a plurality of sets of the discharge part 10 and the piston 20, which allows the discharge parts 10 to be attached/detached to/from the base body 1, and allows the piston 20 to be freely movable in the communication port part 4 when the discharge part 10 is detached from the communication port part 4. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
