VERFAHREN UND EINRICHTUNG ZUR BEREITSTELLUNG VORGEGEBENER FLUIDMENGEN

摘要

A method for delivering a predetermined amount of a fluid comprises the steps of pressurizing the fluid, passing it through a pressure feed passageway, opening and closing the pressure feed passageway, and thereby delivering a predetermined amount of the fluid out of the pressure feed passageway. A rotatable shaft is located in the pressure feed passageway. The rotatable shaft is provided with a passageway part, which constitutes part of the pressure feed passageway. The fluid is delivered by rotating the rotatable shaft to a predetermined orientation, in which the passageway part communicates with the pressure feed passageway outside of the passageway part. After a predetermined amount of the fluid has been delivered, the rotatable shaft rotates by a predetermined angle to an orientation, in which the passageway part does not communicate with the pressure feed passageway outside of the passageway part, and the delivery of the fluid is thereby stopped.
