Abstract: A housing having an interior, including: a) a pressure-compensation-device (PCD), for compensating a pressure in the interior as to surroundings of the housing, the interior being connected with the PCD, and an overpressure-valve (OV) with a lip-sealing-element (LSE) with a main-part and a flexible-sealing-lip (FSL), protruding radially-outwardly from an outer-circumference of the main-part and interacts with a sealing-surface (SS); b) an annular-channel (AC), between the main-part and SS, the FSL being in sealed contact with the SS with elastic-pretensioning in a sealing-position and sealingly closes the AC to prevent a flow-conducting connection between the interior/surroundings, and is lifted away from the SS in an open-position and opens the AC to provide a flow-conducting connection between the interior/surroundings; c) the FSL position between the sealing/open positions is controlled as a function of a pressure-difference between the pressure in the interior/surroundings, d) the main-part of the LSE has

Abstract: The invention relates to a housing (105) having a pressure compensation device (100) for compensating a pressure in an interior (200) of the housing (105) in relation to surroundings (300) of the housing (105), said interior being in connection with the pressure compensation device (100). According to the invention, a main part (125) and a flexible sealing lip (120) of a lip sealing element (115) of an overpressure valve are formed in a single piece from an elastomer material and are held directly in the borehole (205) in a housing wall of the housing (105), a sealing surface (140), with which the flexible sealing lip (120) interacts, being formed by the radially inner circumferential surface of the borehole (205).

Abstract: A releasable-positively-locking-connection (RPLC) between first/second bodies, including: a) a linear-guide between first/second bodies, so that the linear-guide is engage-able; b) a separate-securing-element, fastened releasably by one end in a first-opening in the first-body and/or in a third-opening in a third-body, so that the securing-element protrudes from the first-opening; and c) a second-body section, which is deformable elastically by the separate-securing-element in the longitudinal-axis-direction of the separate-securing-element and has a stop-face, with which the separate-securing-element is contactable; d) the elastically-deformable-section and separate-securing-element interact, e) to assemble the RPLC, e1) the linear guide is engaged between first/second bodies, and e2) first, the first-body is guided linearly in an assembly-direction along the linear-guide, the elastically-deformable-section being contacted by the separate-securing-element which protrudes out of the first-opening, and deforme

Abstract: An apparatus and method for cleaning deposits and accretions from an end plate of a sensor body, for accommodating a measuring apparatus for determining one or more physical and/or chemical, process variables. The sensor body is sealed against penetration by liquid and a wiper is provided having a wiper blade for cleaning the end plate. The wiper is arranged as a subcomponent on a peripheral, appended module, wherein geometries of the wiper and the peripheral, appended module are so embodied that the wiper in the case of rotary movement from a rest position into a cleaning position, with the lower edge of the wiper blade being flush with the upper edge of the end plate, in the cleaning position, and in order that the wiper cleans the end plate by contact of the wiper blade with the end plate, and the wiper then returns to the rest position.
