Japanese Patent JPS5072070
Kind Code:
A
Abstract:
A valve-controlled hydraulic coupling fluid clutch is provided with a reservoir compartment containing first and second chambers, the first chamber receiving liquid from the working chamber during normal operation, while the second chamber receives such liquid only while the turbine is stalled or slowed excessively. Liquid flow means are provided between the two chambers of less capacity than means feeding liquid into the second chamber. Operator controlled valve means between the first reservoir chamber and the coupling working chamber are normally open and upon closing retain liquid in the first reservoir compartment to declutch the coupling, while automatic declutching takes place upon the slowing or stalling of the turbine to prevent overload by removal of working liquid from the working chamber into the second compartment.
