Claims

[Claims for Utility Model Registration] (1) A pair of pump bodies disposed symmetrically via camshafts that cooperate with each other, and a pump body disposed between the center portions of each pump body and with its output shaft. a drive motor that rotationally drives the camshaft, and rotation of the camshaft due to the drive of the drive motor allows the drive shaft portion of the pump section of each of the pump bodies to freely reciprocate against an axial biasing force. The power transmission means is provided with interlocking power transmission means, and a stroke adjustment means that adjusts the stroke length by regulating the amount of axial movement of the drive shaft portion of the pump portion that reciprocates with each of the power transmission means, and the stroke adjustment means adjusts the stroke length. The transmission means is comprised of an eccentric cam mechanism having a pair of eccentric cam members arranged symmetrically apart from each other about the cam shaft, and the rear end side of the drive shaft portion of the pump portion is connected to the rear end side of the drive shaft portion of the pump portion with the eccentric cam mechanism in between A twin reciprocating pump characterized in that the stroke adjusting means is positioned correspondingly on the center axis on the rear end side of the drive shaft portion of the pump portion. (2) The power transmission means includes a worm provided on the output shaft side of the drive motor and a worm wheel provided on the camshaft side, and a pair of eccentric cam mechanisms that rotate eccentrically by rotation of the worm wheel. Utility model registration claim No. 1, characterized in that the cam members are configured to be able to distribute the power transmission force by slidingly contacting them symmetrically with the power transmission parts formed in the middle of the drive shaft part of the pump part. The twin reciprocating pump according to item 1. (3) The stroke adjusting means includes an abutting member located correspondingly along the central axis on the rear end side of the drive shaft portion of the pump portion, and a movable adjustment of the abutting member along the central axis. 2. The twin reciprocating pump according to claim 1, which is characterized by comprising a rotation adjusting body provided with a display scale.
