Abstract

See full text

A vacuum generation system and method utilizes a dual-action piston-cylinder vacuum generation system to evacuate a vacuum storage. Saturated steam of higher than ambient pressure is inserted into a condensation cylinder with two chambers separated by a movable piston. Steam moves the piston to fill one chamber while expel gaseous content and condensate out of the other chamber. Steam is then condensed to a rough vacuum (RV) state by cooling. By repeated operations of inserting and condensing steam in each chamber alternatively, a sustained vacuum generation is achieved. A multi-level vacuum storage is also disclosed with a high vacuum (HV) storage placed inside a rough vacuum (RV) storage to reduce leakage as well as mechanical stresses. The vacuum generation system and method is extended for creating a prime mover or actuator to drive vacuum pumps maximizing thermal energy usage for increased vacuuming capacity.
