Patent ID: 7546679

Claim:
A manufacturing assembly for manipulating objects, the assembly comprising: a structure comprising an internal fluid chamber with a fluid entry port to direct entering fluid toward a controlling aperture and away from a controlled aperture; and a valve assembly comprising: a guide member; and an aperture blocking structure that moves freely in relation to the guide member, wherein the aperture blocking structure normally permits fluid in the internal fluid chamber to be exhausted through the controlling aperture so as to form at the controlled aperture a suction force to attract an object toward the internal fluid chamber, except when the valve assembly is accelerated to create an acceleration force that causes the aperture blocking structure to overcome fluid exhaust forces at the controlling aperture and be forced against and block the passage of fluid through the controlling aperture, in which case fluid within the internal fluid chamber transitions to exhausting through the controlled aperture to repel an object from the internal fluid chamber.
