摘要： A plug connector includes a housing, a locking element and a verification element. The housing has a receiving chamber, a connection piece and a duct through which fluid can flow. The locking element is movable between an open position and a fastening position, a plug can be inserted in the receiving chamber in the open position of the locking element, and a plug inserted in the receiving chamber can be fastened within the receiving chamber via the locking element in the fastening position of the locking element. In an open position of the locking element, the verification element is at least partially covered by the locking element, and in a fastening position of the locking element, the verification element can be read.

摘要： A profile clamp with a clamp band and an annular ring element with a ring body is provided. The clamp band has two clamping heads which are connected to one another via a clamping element. The ring element includes at least one first latching tab, which is arranged projecting from the ring body in the axial direction of the profile clamp and projecting out of the profile clamp at least in some sections. The first latching tab has a first latching portion and a free-swinging portion extending opposite thereto. The first latching portion is designed to exert a force, and the first latching portion has a first contact edge that is designed to create a point contact or a line contact with a flange of the pipe end.

摘要： A jet pump comprising a jet nozzle for accelerating a propellant. The jet nozzle has a convergent inlet part and an outlet part connected to the convergent inlet part. The outlet comprises an inner wall diverging at an opening angle. The opening angle is designed such that a propellant flowing through the outlet part at subsonic speed is detached from the inner wall and a propellant flowing through the outlet part at supersonic speed is guided by the inner wall. An automatic, cost-effective and simple changeover of the jet pump to different pressure ratios is hence provided.

摘要： A profiled clamp having a clamp band and a clamping device which has two clamping jaws arranged at a distance (D) from one another in the circumferential direction (U). The clamping jaws are arranged on each end of the clamp band and can be moved towards one another by means of at least one clamping means. On an inner side of the clamp band, at least two profiled segments are arranged circumferentially spaced apart from one another. The profiled segments can be connected to the clamp band in each case by means of at least one latching connection.

摘要： A profiled clamp for assembling on pipe ends, having a first half-shell and a second half-shell, each of which has a clamping head at a first end and a connection geometry at a second end for releasably connecting the second end. The clamping heads are connected to a clamping element, and at least one of the two half-shells can be tilted relative to the clamping element. A spring element is arranged in the region of the clamping heads, said spring element pushing the second ends of the half-shells apart under pretension. Contact regions of the spring element can be positioned on the pipe ends in a frictionally locking manner when connecting the two ends.

摘要： The disclosure relates to a spring clamp, having a clamp band and a positioning device for pre-positioning the spring clamp on a hose end of a hose. The positioning device having a support band and a contact region, and the support band having. The positioner having a fixing means arranged at the end of the support band, and the support band having a retainer at another end of the support band. A web is formed in the support band between the contact region and the positioner. The support band has at least two regions in the region of the positioner, the first region extending from the web away from the clamp band and the second region extending substantially perpendicularly from the first region.
