  • Patent number: 11548121
    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.

  • Patent number: 9676565
    Abstract: A vacuum gripping device comprising a plurality of suction bodies, each comprising a suction chamber for applying to a workpiece to be gripped, a suction valve is associated with each suction point, wherein each suction valve comprises a vacuum supply side for connection to a vacuum supply device and a suction side connected to the suction chamber of the assigned suction body, wherein the suction valve comprises a valve body, moveable between an open position and a closed position, wherein the valve body is arranged on a flexible control membrane which delimits a control chamber; in such a way that the valve body is moveable from the open position into the closed position using deformation of the control membrane, and wherein a membrane cloth extending across multiple or all suction points is arranged in the gripper housing.

  • Patent number: 9545726
    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.
