VALVE FOR THE SUBSTANTIALLY GAS-TIGHT INTERRUPTION OF A FLOW PATH
First Claim
1. Valve for the substantially gastight interruption of a flow path, comprising:
- a valve housing having a first wall, which wall has a first opening for the flow path, said opening having a geometric opening axis and a valve seat, enclosing the first opening, on a first side of the valve housing,a valve disk havingan, in particular, ring-like or frame-like outer disk portion, anda closed inner disk portion, which is mounted in a seal tight manner such that it is linearly movable within the outer disk portion in a direction parallel to the opening axis relative to the outer disk portion between a retracted setting and an extended setting,at least one drive, which is connected to the outer disk portion and which is configured such that the valve disk is pivotable or displaceable betweenan open setting, in which the valve disk is positioned in a retention portion disposed beside the first opening and frees the first opening and the flow path, andan intermediate setting, in which the valve disk is positioned over the first opening and covers the apertural cross section of the first opening,by means of a transverse motion made substantially transverse to the opening axis, and is displaceable betweenthe intermediate setting anda closed setting, in which a gastight contact, which closes the first opening in a gastight manner and interrupts the flow path, exists between the outer disk portion and the valve seat,by means of a longitudinal motion made parallel to the opening axis, wherein, in the closed setting, a pressure differential at the valve disk acts substantially upon the movable inner disk portion and the inner disk portion is supported in a direction parallel to the opening axis, substantially decoupled from the outer disk portion, directly or indirectly on the valve housingwhereinthe valve seat has a first inner face, which points radially inward and runs parallel to the opening axis,the outer disk portion has a first outer face, which points radially outward and runs parallel to the opening axis and which is arranged and configured such that in the closed setting, via an intervening first seal, there exists a radially sealing contact with the first inner face,the outer disk portion has a second inner face, which points radially inward and runs parallel to the opening axis, andthe inner disk portion has a second outer face, which points radially outward and runs parallel to the opening axis and which is arranged and configured such that, via an intervening second seal a radially sealing contact with the second inner face exists in the region between the retracted setting and the extended setting.

Abstract
A valve for the gastight interruption of a flow path is disclosed. A valve housing includes a first opening and a valve seat. A valve disk includes an inner disk portion, which is linearly movable relative to an outer disk portion so that, in a closed setting, a pressure differential acts substantially upon the movable inner disk portion, which is supported on the valve housing. The valve seat has a radially inward pointing first inner face and the outer disk portion has a radially outward pointing first outer face, wherein in the closed setting there exists a radial sealing contact with the first inner face. The outer disk portion has a radially inward pointing second inner face and the inner disk portion has a radially outward pointing second outer face, having a radially sealing contact with the second inner face.

a valve housing having a first wall, which wall has a first opening for the flow path, said opening having a geometric opening axis and a valve seat, enclosing the first opening, on a first side of the valve housing, a valve disk having an, in particular, ring-like or frame-like outer disk portion, and a closed inner disk portion, which is mounted in a seal tight manner such that it is linearly movable within the outer disk portion in a direction parallel to the opening axis relative to the outer disk portion between a retracted setting and an extended setting, at least one drive, which is connected to the outer disk portion and which is configured such that the valve disk is pivotable or displaceable between an open setting, in which the valve disk is positioned in a retention portion disposed beside the first opening and frees the first opening and the flow path, and an intermediate setting, in which the valve disk is positioned over the first opening and covers the apertural cross section of the first opening, by means of a transverse motion made substantially transverse to the opening axis, and is displaceable between the intermediate setting and a closed setting, in which a gastight contact, which closes the first opening in a gastight manner and interrupts the flow path, exists between the outer disk portion and the valve seat, by means of a longitudinal motion made parallel to the opening axis, wherein, in the closed setting, a pressure differential at the valve disk acts substantially upon the movable inner disk portion and the inner disk portion is supported in a direction parallel to the opening axis, substantially decoupled from the outer disk portion, directly or indirectly on the valve housing wherein the valve seat has a first inner face, which points radially inward and runs parallel to the opening axis, the outer disk portion has a first outer face, which points radially outward and runs parallel to the opening axis and which is arranged and configured such that in the closed setting, via an intervening first seal, there exists a radially sealing contact with the first inner face, the outer disk portion has a second inner face, which points radially inward and runs parallel to the opening axis, and the inner disk portion has a second outer face, which points radially outward and runs parallel to the opening axis and which is arranged and configured such that, via an intervening second seal a radially sealing contact with the second inner face exists in the region between the retracted setting and the extended setting. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14)
