Abstract
A pneumatic system for a surgical machine includes a reservoir, first and second proportional valves, and a controller. The reservoir holds pressurized gas. The first proportional valve is located on an input side of the reservoir and allows a variable amount of pressurized gas to enter the reservoir. The second proportional valve is located on an output side of the reservoir and allows a second variable amount of pressurized gas to exit the reservoir. The controller controls the operation of the first and second proportional valves. The controller adjusts the first and second proportional valves so that a constant gas pressure range is maintained at an output of the reservoir over a first range of input gas pressures and a second range of gas usage.
