Abstract
The invention includes a bi-directional air release valve for the tank system of a motor vehicle having an inlet opening, an outlet opening, a valve seat placed between the openings, and a closure element. In a closed position the closure element blocks the flow communication between the inlet and outlet openings and in its opened position releases the blockage. The closure element is activated by a motor such that it may be adjusted to bring about optional intervening positions.
