Rotary Vane Vacuum Pump Question

[QUOTE="Baluncore, post: 6535809, member: 447632"] The pressure starts out the same. As the inlet port is exposed, the pump chamber has a minimum volume which quickly matches the pressure at the input port. The volume of the pump chamber is then increased, so the pressure falls as the total volume of the connected input and pump increases. Gas is shared between the port and pump volumes, so gas is drawn from the inlet port into the pump chamber as the volume increases and pressure falls. [/QUOTE]
