Abstract: Provided is a vacuum cleaner. The switching valve apparatus of the vacuum cleaner includes an outer casing and a counterflow air passage. The outer casing is provided with a first vent opening and a second vent opening arranged side by side along the circumferential direction of the outer casing. In the case where the counterflow air passage is at the first angular position, the outer casing seals the counterflow air outlet of the counterflow air passage; in the case where the counterflow air passage is at the second angular position, the counterflow air outlet communicates with the first vent opening and is staggered with the second vent opening; and in the case where the counterflow air passage is at the third angular position, the counterflow air outlet communicates with the second vent opening and is staggered with the first vent opening.

Abstract: A connecting apparatus for the connection of a valve rod (4) to a closure member (1) of a vacuum valve, with a connecting body (12) which is arranged between a first connecting part (10) and a second connecting part (11). The connecting body (12) has a basic shape of a Steinmetz body which is formed by way of a intersection of two circular cylinders. The connecting body (12) is arranged in an intermediate space between arm projections (24, 25) of the first connecting part (10) and in an intermediate space between arm projections (26, 27) of the second connecting part (11). Corresponding bearing faces (28, 29, 30, 31) of the arm projections (24, 25, 26, 27) bear against bearing faces (13, 14, 15, 16) of the connecting body (12). The two arm projections (24, 25, 26, 27) of the respective connecting part (10, 11) approach one another towards their free ends.

Abstract: The invention relates to a vacuum valve (10) for the substantially gas-tight closure of an opening defining an opening axis, comprising a closure element (14) having a closure side and a coupling unit arranged on a rear side opposite the closure side, and a valve wall having valve seat (12a) surrounding the opening. The valve further comprises a linear drive unit by means of which the closure element (14) is adjustable in at least two adjustment directions substantially orthogonally to the opening axis along an adjustment axis and thus the closure element (14) is adjustable between an open position releasing the opening, an intermediate position pushed over the opening and a closed position closing the opening. The vacuum valve (10) comprises a guide for the closure element (14) associated with the opening. The closure element (14) comprises a guide element (25) interacting with the guide during an adjustment from the open position to the closed position and back, and the guide and the guide element (25) are shaped and interact in such a way that, in the course of the adjustment from the intermediate position to the closed position, a tilting of the closure element (14) transversely to the adjustment axis is initiated and/or effected in a first partial movement.

Abstract: Disclosed is a vacuum valve having a valve seat, which has a valve opening, defining an opening axis, and a first sealing surface, a valve closure having a second sealing surface corresponding to the first sealing surface, a drive unit coupled to the valve closure, which can be moved from an open position, in which the valve closure and the valve seat do not contact each other, to a closed position, in which there is a sealing contact between the first sealing surface and the second sealing surface by a seal there between, and the valve opening is sealed gastight as a result. The vacuum valve has at least one temperature sensor, where the temperature sensor is designed and arranged such that, from the temperature sensor, a measurement signal representing thermal information in respect of at least one part of the vacuum valve can be detected.

Abstract: A spacer having a wedge-shaped flat plate portion and an engagement protrusion is interposed between a hole end surface of mounting hole of a valve plate and a rod end surface of mounting portion of a valve rod, which thereby forms a wedge-shaped gap between the spacer and the hole end surface so as to open frontward. A fastening force of a valve-plate fixation screw generates a moment M that deforms the valve plate in a direction of narrowing the gap. At the same time, the engagement protrusion of the spacer is pressed into a wedge-shaped space between the inclined surface portion of the rod end surface and the rear hole-wall surface of the mounting hole, which causes the front hole-wall surface of mounting hole of the valve plate to press the rod front surface of mounting portion of the valve rod.

Abstract: A closure device (1) for an opening (2) in a chamber wall (3) is provided, wherein the closure device (1) has at least one closure element (4) and at least one closure element carrier body (5) and at least one yoke (6). The closure element (4) is fixedly connected to the yoke (6) by the closure element carrier body (5), wherein the yoke (6) is mounted in a housing (9) of the closure device (1) in such a way that the yoke can be slid by at least one cylinder-piston drive unit (7) of the closure device (1), in particular parallel to a longitudinal extent (8) of the closure element carrier body (5). The yoke (6) has at least one cylinder cavity (10) of the cylinder-piston drive unit (7) and/or at least one guide element receptacle (11) for guiding a guide element (12) of the closure device (1).

Abstract: A vacuum-sealed container wherein a large negative pressure is applied inside the container without using a pump, making it possible to store food for a long time; the container can be sealed without using a packing. The vacuum-sealed container includes: a container body having a lid coupling groove formed along the periphery of the upper end portion of an opening and arranged along a closed path; a lid body formed to be convex upward using an elastic material, the lid body having a sealing portion formed thereon such that the same is inserted into the lid coupling groove along the periphery thereof so as to seal the inside of the container body; and a valve installed on the lid body so as to provide a passage, through which air inside the container body is discharged to the outside, and so as to expose/cover the passage.

Abstract: Provided is a valve 130 which requires only a small space for the open/close operation of an opening 113 in a partition wall. A sealing part 140 includes a sealing member 141 for sealing the opening by being pressed onto the partition wall around the opening. An urging means 144 urges the sealing member 141 against the opening when the sealing member 141 is in contact with the opening. A driving means 160 generates a driving force orthogonal to an opening central axis A which is an axis perpendicular to a partition plate 111 and passing through the center of the opening. A linkage 150, which is a Scott Russell linkage connecting the sealing part 140 and the driving means 160, converts the driving force of the driving means 160 into a driving force which is parallel to the opening central axis A and makes the sealing part 140 move along the same axis.

Abstract: A closure device including a closure element for closing an opening surrounded by a valve seat of the closure device. The closure device has an open state, in which the closure element exposes the opening at least partly, for an object to be led through the opening, an intermediate state, in which the closure element is brought into alignment with the opening without contact with the valve seat, and a closed state, in which the closure element at least rests on the valve seat via a seal of the closure device. The seal has a hollow space, to which a pressure medium from a pressure source of the closure device can be applied, and the closure device has a suction apparatus for sucking the pressure medium out of the hollow space of the seal.
