Abstract
PURPOSE:To send a little fluid always by a constant quantity, by means of utilizing the volume change due to the bending of a fluid tube. CONSTITUTION:When source voltage is immpressed on a synchrous motor 12, an axis 13 rotates by the rotation number determined by a source frequency, thereby a fluid actuating tube 6 is allowed to be displaced and be bended periodically in its free end 7. Then, the volume of an inner space 9 is little changed with accuracy by means of generating the change to the shape of the cross section of the fluid actuating tube 6. And because that the volume change of above mentioned inner space 9 is so constituted as to be conducted to a space 4, when the inner space 9 is increased, the fluid is absorbed in the space 4 from an inflow entrance 2 by means of being opened by a cheque valve 5 and of being closed by a cheque valve 6, and when the inner space 9 is reduced, the fluid of the space 4 is outflowed from an outflow exit 3 by means of being closed by the cheque valve 5 and of being opened by the cheque valve 6. The fluid is sent by the action of the pump as arrow marks by means of being performed continuously by said action.
