Valve with a valve housing (22) which has a vacuum supply side (28) and a suction side (30), with a flexible dividing wall (34) which delimits a control space (36) in the valve housing, which control space communicates with the vacuum supply side, and with a valve body (38) which is arranged on the flexible dividing wall and can be moved between an open position and a closed position, wherein the valve body has a sealing portion (44) which, in the closed position, bears against a sealing seat (64) in order to seal the vacuum supply side with respect to the suction side, and wherein, depending on a vacuum occurring in the control space, the volume of the control space is reduced with deformation of the flexible dividing wall and in the process the valve body is moved from the open position into the closed position. Here, the valve body has a suction side passage (54) for flow connection of the control space to the suction side, and the sealing portion and the sealing seat are arranged in such a way that, in the closed position, the flow connection through the suction side passage is sealingly closed. The sealing portion is arranged outside the control space. |
