Abstract: An assembly having at least two chambers (1, 2) and at least one transfer valve (3), wherein: a valve housing interior (9) of the transfer valve (3) is separated from each the chamber interiors (4, 5) of the chambers (1, 2) by respective partitions (12, 13) and a transfer opening (14, 15) for the feeding through of objects and/or fluids is formed in each of the partitions (12, 13) and in addition to the transfer opening (14, 15) in question an additional opening (16, 17) is arranged in each of the partitions (12, 13). The additional openings (16, 17) can be closed by respective switching valves (18, 19) of the assembly and, in an open state of the respective switching valves (18, 19), directly fluidically connect the valve housing interior (9) to the respective chamber interiors (4, 5) adjoining the respective partitions (12, 13).

Abstract: A valve with a closure member that, in its closed position, seals the through-opening, with the interposition of the seal against the valve seat, and is movable into the closed position by a relative movement between the closure member and the supporting member. The supporting member, in the closed position of the closure member, is supported on the abutment seat. The valve also has at least one grounding element for electrically grounding the closure member in its closed position, fastened on a carrier component of the valve. The carrier component is the closure member, the supporting member, the valve seat, or the abutment seat. The grounding element has a contact element and a supporting element, which is connected to the contact element, and the contact element and the supporting element are formed of mutually different materials or material compositions and the contact element is softer than the supporting element.

Abstract: A vacuum valve with a valve housing with a valve opening, a closing element, and at least one peripherally closed seal on the closing element with first and second seal main sections and first and second seal connecting sections allocated to corresponding seat main sections and connecting sections. The seal extends in a groove defined by two side walls and a base wall. The first seal main section is arranged on a front end face of the closing element and has a middle part where the seal extends in a straight line. The seal is clamped by a clamping bar at least across part of the middle part, with the clamping bar fixed on the closing element and forming one of the side walls. Through at least one second sub-region of the longitudinal extent of the seal, the two side walls and base wall are formed by the closing element.

Abstract: For a vacuum valve comprising a valve housing (1) with a valve opening, a valve seat surrounding the valve opening, a closing element (9), and at least one peripherally closed seal (10, 11) that is arranged on the closing element (9) and has first and second seal main sections (14, 15) and first and second seal connecting sections (16, 17) allocated to first and second seat main sections arranged offset relative to each other in a direction of the axis (3) of the valve opening (2) and first and second seat connecting sections, is provided, with the seal extending in a groove that is defined, when viewed in cross section, by two side walls and a base wall. The first seal main section (14) is arranged on a front end face (18) of the closing element (9) with respect to the closing direction (8) of the closing element and has a middle part (19) in which the seal (10, 11) extends in a straight line.
