92: <VUR10> c Use of vacuum pressure in VEX U pneumatics systems


WPI
2-Oct-2018

> <VUR10> Teams may utilize commercially available pneumatic components from the following list:

Cylinders, actuators, valves, gauges, storage tanks, regulators, manifolds, and solenoids. c. Pneumatic devices may only be charged to a maximum of 100 psi.

There is a maximum pressure, but no minimum pressure. Assuming the components used are allowed by <VUR10> and rated for vacuum pressure by the manufacturer, would the limit of 100psi also apply to vacuum pressure? If so, would vacuum heads be considered legal pneumatic actuators by VUR10?

Answered by Game Design Committee

Yes, vacuum heads would be considered legal pneumatic devices within the scope of <VUR10>. If using a Venturi pump, which uses positive pressure to create negative pressure, the operating pressure would be bound by the 100psi limit.
