A sorting system () for sorting sorting objects (), including a sensor unit () which is adapted to detect a property, in particular a size, shape, weight, color and/or material, of a sorting object (), and a valve arrangement () which is adapted to blow on the sorting object () in order to convey the sorting object () to one of a plurality of possible sorting destinations (), wherein the sorting system () is adapted to selectively set, according to the detected property, a blowing strength () to a first blowing strength (A) greater than zero or to a second blowing strength greater than zero, the second blowing strength being different from the first blowing strength (B), and to blow the sorting object using the valve arrangement with the set blowing strength to cause the sorting object to be conveyed to the sorting destination.

Sorting method and sorting device

An actuating device mechanically controls a membrane pump device. The device includes a base body having a mounting face for a membrane pump device and through which a control fluid line passes that extends from a control fluid port to a control fluid opening that opens at the mounting face. A control fluid valve arranged in the control fluid line influences a cross-section of the control fluid line and has an adjustment device that has a fluid actuator arranged on the mounting face. A working fluid valve influences a cross-section of a working fluid line that passes through the base body. The control fluid valve and the working fluid valve are electrically connected to a control device that electrically controls the control fluid valve and the working fluid valve. Moreover, a membrane pump is provided that has an actuating device and a membrane pump device.

Operating device, method for operating an operating device, diaphragm pump having an operating device and a diaphragm pump device, and a blood treatment apparatus having a diaphragm pump

The invention relates to a membrane pump devicefor conveying fluids, in particular medical liquids for blood treatment. The invention furthermore relates to a membrane pump with a membrane pump deviceand an actuating devicefor the membrane pump device. The membrane pump devicehas a pump chamber bodyin which a recess, which is closed by an elastic membraneto form a pump chamber, is constructed. The membrane pump devicemoreover comprises an inward flow pathwhich connects an entry connectionto an inlet openingof the pump chamber, and an outward flow pathwhich connects an outlet openingof the pump chamberto an exit connection. An inlet valveis provided in the inward flow pathand an outlet valveis provided in the outward flow path. The outlet valveis a membrane valve which has a valve bodyA in which a recess is constructed which is closed by an elastic membraneto form a valve chamberin which a valve seatis arranged, the front face of which faces the membrane and in the open position of the outlet valve is arranged at a distance from the valve seat, wherein a valve channelpasses through the valve seat. The outward flow pathcomprises a first outward flow channelwhich connects the outlet openingof the pump chamberto the outlet valve chamber, and a second outward flow channelA which connects the outlet valve chamberto the exit connection, wherein the cross-section area of the outlet valve channelis smaller than the cross-section area of the region of the valve chambersurrounding the outlet valve seat

Diaphragm pump device and diaphragm pump having a diaphragm pump device and an actuation device

The invention relates to a coupling component for a fluid coupling () for releasably connecting fluid-conveying components, in particular fluid-conveying components in medical equipment, wherein the coupling component comprises a coupling housing () through which a fluid channel () passes in regions and which is provided with a coupling recess () that is sunken into a surface () of the coupling housing (), wherein a channel opening () of the fluid channel () ends at an end face () of the coupling recess (). According to the invention, it is provided that the channel opening () is covered by a membrane seal () which is made of a resilient material and through which a fluid gap passes () that is designed such that the membrane seal (), when in a resting position, seals the channel opening () and, when in an operative position, opens the channel opening (), wherein at least one yielding depression () is formed in the coupling recess () adjacently to the channel opening (), which depression is designed for an yielding movement of a region () of the membrane seal () when the membrane seal () transitions from the resting position into the operative position.

A method for operating a vacuum gripping device including a suction gripper unit, which is provided with at least one suction gripper. The suction gripper unit can be connected, via a control valve device connected to it, selectively to a vacuum source or to a positive pressure source generating an ejector pulse in the suction gripper. The ejector pulse is generated as a function of the actual pressure established in the suction gripper unit after its connection to the positive pressure source. A vacuum gripping device suitable for executing this method and including a pressure measurement device for detecting the actual pressure and an electronic control unit used for controlling the control valve device and communicating with the pressure measurement device.

Vacuum gripping device and method for operating a vacuum gripping device

A piezoelectric actuator device, with at least one piezoelectric transducer which has at least one piezoelectric body and an electrode unit assigned to this piezoelectric body, with overall capacitance and including two electrodes lying opposite one another. At least one of the two electrodes of the electrode unit is divided into several individual sub-electrodes, spaced apart from one another and forming with the electrode lying opposite several sub-electrode pairs defining in each case a partial capacitance of the overall capacitance. A separate current-limiting resistor active during charge flow is connected in series to each sub-electrode pair. A valve, for controlling a fluid, is equipped with such an actuator device.
