Abstract
A valve has suction and vacuum supply sides and a valve housing inbetween, a flexible dividing wall delimiting a control space in the valve housing connected to the vacuum supply side via a vacuum passage, and a valve body arranged on the dividing wall moving between open/closed positions. The valve body has a sealing portion sealing off or opening up the vacuum passage in closed/open positions. Based on a control space vacuum, the volume of the control space reduces with a deformation of the dividing wall, and the valve body moves from the open to closed position. The valve body has a suction-side passage connecting the suction side to the control space so air is suctioned from the suction side into the control space, and penetrates the dividing wall with the sealing portion on one side and a guide portion on the other side of the dividing wall.
