Patent number: 11906066Abstract: A seal support ring (1) for a valve (2), particularly a vacuum valve, which has a throughflow opening (3) and a basic body (4), which annularly surrounds the throughflow opening, and a fastener arrangement (5) for fastening the seal support ring to a valve housing (6) of the valve. The basic body has a first side (7) on which the seal support ring, in a mounted state on the valve housing, lies against the valve housing, and the seal support ring has a seal ring (8) made from an elastomer which, in its position on the basic body, surrounds the throughflow opening. A casing wall (9) is arranged on the basic body and at least partially surrounds the throughflow opening and, on a second side (10) of the basic body (4) opposite the first side, protrudes from the basic body and has a larger inside diameter than the seal ring.Type: GrantFiled: March 30, 2022Date of Patent: February 20, 2024Assignee: Vat Holding AGInventors: Christof Bachmann, Hanspeter Frehner, Martin Netzer, Florian Ehrne

Patent number: 10539253Abstract: A vacuum valve has a valve opening (2, 3) that is surrounded by a valve seat (6, 7), a valve plate (10, 11) that releases the valve opening (2, 3) in an open state and rests against the valve seat (6, 7) in a closed state, and a carrier unit (9) that supports the valve plate (10, 11) and moves between a first position, in which the valve opening (2, 3) is in the open state, and a second position. The valve plate (10, 11) moves between a retracted position and an extended position. In the second position of the carrier unit (9) and in the extended position of the valve plate (10, 11), the valve opening (2, 3) is in the closed state. In the retracted position, the valve plate (10, 11) is supported against the carrier unit (9).Type: GrantFiled: February 19, 2016Date of Patent: January 21, 2020Assignee: VAT Holding AGInventors: Florian Ehrne, Christof Bachmann, Daniel Seitz

Publication number: 20180163877Abstract: A valve with an opening surrounded by a seat, and a closure member, which, in a closed position, presses onto the seat and closes the opening and, in an intermediate position, is raised from the seat and overlaps with the opening and, in a maximum opening position, at least partially releases the opening. The valve has a frst valve drive for moving the closure member between the maximum opening position and the intermediate position along a first movement track, and a second valve drive for moving the closure member between the intermediate position and the closed position along a second movement track which is at an angle to the first movement track. The valve has at least one transmission part which is provided for reversible deformation by the second valve drive, and the first valve drive acts on the closure member with the interposition of the transmission part.Type: ApplicationFiled: February 7, 2018Publication date: June 14, 2018Applicant: VAT Holding AGInventors: Florian Ehrne, Christof Bachmann, Matthias Wozasek

Publication number: 20180045333Abstract: A vacuum valve is provided having a valve housing (1) with a valve opening (2, 3) that has an axis (4, 5) and is surrounded by a valve seat (6, 7), a valve plate (10, 11) that releases the valve opening (2, 3) in an open state of the valve opening (2, 3) and rests against the valve seat (6, 7) in a closed state of the valve opening (2, 3), and a carrier unit (9) that supports the valve plate (10, 11) and can be moved between a first position, in which the valve opening (2, 3) is in the open state, and a second position. The valve plate (10, 11) is connected to the carrier unit (9) via at least two spaced drive elements (20) of the carrier unit (9) and can be moved between a retracted position and an extended position by the drive elements (20). In the second position of the carrier unit (9) and in the extended position of the valve plate (10, 11), the valve opening (2, 3) is in the closed state.Type: ApplicationFiled: February 19, 2016Publication date: February 15, 2018Applicant: VAT Holding AGInventors: Florian Ehrne, Christof Bachmann, Daniel Seitz
