Abstract: In a method for positioning a closure element of a valve or ejector, said closure element being movable by means of a drive between a first end position and a second end position, the closure element is moved into one of the first end position and the second end position and, after the closure element has been moved into the one end position, a compensation cycle is performed during which the closure element is controlled to perform a first compensation movement towards the other end position and to perform a second compensation movement towards the one end position.

Abstract: The present invention relates to a device (1) for measuring a liquid level of a medium at a high temperature in a container (5), having a measuring unit (10) with a measurement chamber (15) and a measuring instrument (20) for determining the liquid level in said measurement chamber, and having a connecting feature (30) for connecting said measuring unit (10) with said container (5) at a distance and for transferring the medium from said container (5) into said measurement chamber (15), wherein said connecting feature (30) has an attachment adapter (35) for fastening to said container (5) and a connection adapter (45) for connecting to said measuring unit (10), wherein said attachment adapter (35) and said connection adapter (45) are arranged at a distance by at least two connecting lines (40) along an axis (X). Furthermore, the present invention relates to a refrigerating machine having such a device.

Abstract: In order to provide a shut-off valve including a valve housing, a valve seat which is held on the valve housing, and a valve element (40) which is movable in the valve housing relative to the valve seat and is movable by means of an adjusting unit, wherein the shut-off valve, as a result of its construction, has the smallest possible flow resistance in the open position of the valve element, it is proposed that the valve element should have a valve disc (74) which is provided, on its side facing the valve seat, with a sealing element (90) that abuts against the valve disc.
