Title:
SPEEDDVARIABLE FLUID COUPLER
Document Type and Number:
Japanese Patent JPS5663130
Kind Code:
A
Abstract:
PURPOSE:To lessen agitating loss by a flap tube for improving the efficiency of operation by jointly providing a switch valve to increse or decrease the amount of working oil multistepwise according to power loss generated in a speed-variable fluid coupler on the way of a working oil supply pipe. CONSTITUTION:Oil compressed by a pump 9 is supplied through switch valves 10a and 10b to a fluid coupler 2 and circulated by a flap tube 8. Since the switch valves 10a and 10b are arranged in parallel plurally, the flow rate of working oil can be changed multistepwise A, B and A+B by controlling combination of ON and OFF of each switch valve in a manner that the switch valves are switched stepwise according to power loss P1 generated in the speed-variable fluid coupler.
