Abstract:
The invention relates to a suction device (12) comprising a valve housing (18), a flexible partition wall (28) which runs in such a way that a control space (30) extends on one side and an intake side (21) lies on the other side, wherein the control space (30) is connected to the intake side (21) via a throttle passage (38), wherein the throttle passage (38) is formed in such a way that a flow resistance for flows is defined by the throttle passage (38) in such a way that, in the case of free suction, a negative pressure in relation to the intake side occurs in the control space (30) on account of the flow resistance. A sealing protrusion (44) protruding into the interior of the control space (30) and an associated seal seat (50) within the control space (30) are provided, wherein the sealing protrusion (44) and seal seat (50) are formed in such a way that, when the sealing protrusion (44) is placed against the seal seat (50), the flow path (40) through the throttle passage (38) into the control space (30) is interrupted within the control space (30).
