Zusammenfassung:	A valve assembly includes a seat separating a cavity of a valve body into a first cavity portion and a second cavity portion. The assembly includes a cover device separating the first cavity portion into a first pocket and a second pocket. The cover device defines at least one hole to provide fluid communication between an aperture of the seat and an outlet of the valve body via the hole. The cover device is movable between a rest position to restrict fluid communication between the aperture and the hole, and an actuated position to increase fluid communication between the aperture and the hole when a vacuum is created in the first cavity portion. The aperture is in direct fluid communication with the first pocket when in the actuated position. The outlet is in direct fluid communication with the second pocket when in the rest and actuated positions.
