  • FLUID DEVICE WITH MAGNETIC LATCHING VALVES
    Publication number: 20100307599
    Abstract: A method of valving a fluid device includes receiving a signal that is correlated to a displacement of a volume chamber of a displacement assembly of a fluid device. A check ball is delatched from a magnetic pole of a first latch valve that is in fluid communication with the volume chamber and a fluid inlet of the fluid device when the displacement of the volume chamber reaches a first value. A check ball is delatched from a magnetic pole of a second latch valve that is in fluid communication with the volume chamber and a fluid outlet of the fluid device when the displacement of the volume chamber reaches a second value.
