Patent number: 11959563Abstract: A membrane valve, with a valve housing, in which a housing interior is formed, in which housing interior a flexible control membrane is arranged. A drive plunger lies opposite a valve seat and the drive plunger has a shank body with a peripheral outer lateral surface. The outer lateral surface of the shank body of the drive plunger at least in the region of a guide section has a polygonally contoured prismatic shaping with a succession of outer side edges and outer side surfaces, wherein the edges and surfaces extend in the plunger longitudinal direction and the succession alternates in the circumferential direction of the drive plunger.Type: GrantFiled: July 27, 2022Date of Patent: April 16, 2024Assignee: Festo SE & Co. KGInventors: Andreas Bühler, Bengt Erich Wunderlich, Tobias Schuster

Patent number: 11697115Abstract: A dispensing device which has a dispensing channel extending between a supply opening and an output opening into the course of which a pump, a selection valve and a dispensing valve are connected. The selection valve is also connected to a pressurised air source. The dispensing device allows a dispensed output of a fluid, wherein a buffer channel portion is filled by the pump in a pump dispensing phase, to which buffer channel portion pressure is applied from the pressurised air source during a pressurised air dispensing phase such that a precise fluid output is subsequently possible by clocked actuation of the dispensing valve until the target fluid amount has been reached.Type: GrantFiled: September 13, 2018Date of Patent: July 11, 2023Assignee: FESTO SE & CO. KGInventors: Bengt Erich Wunderlich, Bernhard Vogt, Duc-Thang Vu

Patent number: 11560954Abstract: A valve for controlling a fluid flow, including a valve housing, which is provided with a first fluid connection, a fluid channel and a second fluid connection, further including a valve member which is pivotally mounted in the fluid channel, and a drive for introducing a movement onto the valve member, the valve member having a rigid carrier and a flexible membrane with a sealing region which is provided for a sealing abutment against a valve seat and which is fixed to the carrier and to the valve housing by a circumferentially formed fastening region, wherein a deformation region of the flexible membrane is located between the sealing region and the fastening region and is arranged between a first deformation plane and a second deformation plane, the first deformation plane and the second deformation plane each being aligned parallel to a pivot axis determined by the pivot pin and delimiting a deformation space, and wherein the pivot pin is accommodated at least partially in the deformation space.Type: GrantFiled: June 16, 2021Date of Patent: January 24, 2023Assignee: Festo SE & Co. KGInventors: Bernhard Vogt, Stefan Schietinger, Bengt Erich Wunderlich, Sascho Zadravec, Lukas Grad

Publication number: 20220228897Abstract: Dosing unit for dosing liquids, having a fluid unit for selectively providing an overpressure and a negative pressure on a working gas, which is accommodated in a fluid channel which is connected at a first end region to the fluid unit and which includes a second end region, having a first valve unit and having a second valve unit, which are arranged spaced apart from one another along the fluid channel and are each designed for selectively blocking or releasing the fluid channel, wherein a fluid reservoir is delimited by the first and second valve units, the fluid reservoir storing a working gas. The dosing unit further includes a control unit for controlling the valve units, the fluid reservoir being assigned a pressure sensor which is designed to provide a pressure signal as a function of a working gas pressure and is electrically connected to the control unit.Type: ApplicationFiled: April 7, 2022Publication date: July 21, 2022Inventors: Martin Bochterle, Bengt Erich Wunderlich, Matthew Peterson
