For position 1: (a) depicts the initial position, (b) depicts the suction semicycle, and (c) depicts pumping semicycle. For position 1 the fluid enters through the bright blue tubing and exits through the dark blue tubing. For position 2, after the system is turned up-side-down, (d) depicts the initial position, (e) depicts the suction semicycle, and (f) the pumping semicycle. For position 2 the fluid enters through the dark blue tubing and exits through the bright blue tubing. The gravitational reference points downwards for all drawings.
