A rotary compression pump works in cycles. Over each cycle a volume is created in contact with the chamber where pressure is to be lowered. By random motion, molecules from the vacuum chamber pass into the volume created by the pump. This volume is then cut off from the chamber and compressed in contact with a one way valve. If the volume is compressed enough some of the molecules will pass through the valve.
