ABSTRACT:
A liquid friction coupling comprises a housing that contains a viscous liquid, a shaft protruding into said housing, alternating and interdigitating inner and outer blades, which are axially slidably and non-rotatably connected to the shaft and to the housing, respectively, annular expanding springs, which extend between adjacent inner blades or outer blades, and an annular piston, which is sealed in the housing and axially displaceable therein and is operable from the outside and arranged to act on the blades in order to change the blade spacing. In order to increase the range in which the blade spacing can be controlled and possibly to permit the coupling to be used as a clutch coupling, the volume of the viscous liquid which is contained in the housing equals the total volume of the free spaces in the housing outside the outer periphery of the inner blades when the piston is in the position which corresponds to the largest blade spacing.
