Empty liquid coupling with continuous control of the fluid quantity to power the workspace, with or without internal device for direct connection of the driving and driven shaft.

摘要

In a fluid coupling (1) of emptying type, means are provided for continuously feeding fluid into the operating circuit in order to gradually and accurately obtain the degree of filling of the cavity (7) on which the rotation speed of the exit shaft (60) depends. A feed pump (27) is used preferably operated directly by an electric motor (124) the rotation speed of which is varied by a frequency converter (122). To connect the shafts (50, 60) directly together, the coupling can be provided with a means (30) located in the interior of the coupling and operated by a pump (29) forming part of a separate circuit. A microprocessor (D) is used to automate the operation of the coupling. IMAGE
