Abstract
A suction device may include a suction channel, a first valve, and a second valve. The suction channel may include a first suction portion and a second suction portion disposed opposite one another in a transverse direction. The first valve may be arranged in the first suction portion. The first valve may include a first valve seat and a moveable first valve body. The second valve may be arranged in the second suction portion. The second valve may include a second valve seat and a moveable second valve body. When a transverse acceleration is equal to or greater than a predefined transverse acceleration, one of the first valve and the second valve may close while the other one of the first valve and the second valve remains open. When the transverse acceleration is less than the predefined transverse acceleration, the first valve and the second valve may both be open.
