Abstract

PURPOSE: To provide a means to reliably transfer a substance in constant volume by supporting a rotating member having a cylinder chamber rotatably in a base and providing a piston which reciprocates synchronously with the rotation of said rotating member in the cylinder chamber.
CONSTITUTION: A rotating member 7 connected to a driving means 11 is rotatably supported in a base 1, said rotating member 7 having a cylinder chamber 8 and a pinion 14 installed therein, said cylinder chamber 8 having a piston 9 which engages with said pinion 14, and said base 1 having a fixed gear 20 engaged with a spur gear 19 coaxially connected with the pinion gear 14. When the rotating member 7 is rotated by the driving means 11, the spur gear 19 engages with the fixed gear 20 to move a piston 9 which is positioned at one end of the cylinder chamber 8 to the opposite end and sucks and discharges the substance to be transferred when the cylinder chamber 8 faces an introduction port 3 and a discharge port 4 thereby providing a means to reliably transfer a substance in constact volume through simple configuration.
