16. The motor and valve assemblies A B valve subsystem inlet outlet valve subsystem and plunger drive subsystem are detailed in the following sections During infuser operation the mechanism assembly plunger motor drives a lead screw that is coupled to the plunger The motor action and lead screw move the plunger forward to cause the delivery of approximately 0 33 mL of fluid per cycle The plunger motion is synchronized to the valve motors to provide controlled fluid delivery 4 5 2 1 MOTOR AND VALVE ASSEMBLIES The mechanism assembly pumping action is controlled by three stepper motors The first stepper motor in conjunction with an associated valve assembly activates the A valve or the B valve of the cassette depending on the command The second stepper motor alternately opens and closes the inlet and outlet valve to control fluid delivery through the cassette pumping chamber A third stepper motor controls plunger movement Technical Service Manual 4 29 430 10996 001 Rev 12 05 SECTION 4 THEORY OF OPERATION 4 5 2 2 A B VALVE SUBSYSTEM The A B valve subsystem includes a motor designed to rotate a cam When the cam is positioned at top dead center home position both valves are closed Clockwise rotation when viewed from the motor side from the home position opens the A valve while the B valve remains closed Counterclockwise rotation opens the B valve while the A valve remains closed see Figure 4 8 The A B valve subsyst
