The invention relates to a closure with a thermal safeguard function, comprising a closure body (), which is used to seal a cavity () that is to be closed; a fusible safeguard element (), which is inserted into the closure body and which keeps closed, at least indirectly, a through-opening (), which is formed in the closure body. The inventive closure with a thermal safeguard function is characterized by the following features: the closure body comprises a bushing () provided with a continuous bore (); the bushing is inserted into the through-opening of the closure body at an axial end () in such a way that the continuous bore and the region of the through-opening that is axially adjacent to the bushing are aligned flush with each other; the fusible safeguard element completely fills the continuous bore of the bushing over the entire cross section thereof along a given axial length.

Closure with a thermal safeguard function

A hydrodynamic machine with a turbo coupling comprising primary and secondary wheels together forming a torus shaped workspace, which can be filled with a working medium. A temperature-sensing device installed in a component, which rotates when the machine is operating, and sending a temperature &#x2014;dependant signal. A stationary monitoring device connected to the temperature sensor in a remote query connection, and having means for creating a temperature measurement correction depending on the heating rate progression of the sensed temperature.

The disclosure concerns a pumping apparatus for working fluid, in a hydrodynamic coupling, or the like. Working fluid is stored in a sump and is to be lifted by a spinning disc to an elevated container from which the working fluid is then directed back into the spinning disc. The periphery of the spinning disc picks up the working fluid from the sump and carries it around to spary it up toward a deflector at the top of the housing which deflects the fluid into the container. A groove-like duct encloses the lower quarter of the disc for directing the fluid back toward the surface of the disc. The disc has a trapezoidal cross-section peripheral groove for further carrying the fluid beyond the top exit of the duct so that the fluid may be thrown toward the deflector at the top of the housing.
