Abstract

PURPOSE: To enhance the respondence of a controller for the revolving number of an output shaft by moving the position of a flash pipe during the decelerated or accelerated or acclerated period by providing an oil pressure switch valve controlled according to a deviation between the detected value and target value of the revolving number of the output shaft, etc., in the way of a working oil supply pipeline.
CONSTITUTION: In a variable-speed fluid coupler having an impeller 2 connected with a driving shaft 1 and a runner 3 connected with an output shaft 4 facing the impeller 2, the revolving number of the output shaft is changed by varying the amount of a working oil inside a working chamber 5 by moving a flash pipe 8 inserted into a flash pipe chamber 6 formed by a casing 7. In this case, an electromagnetic oil pressure switch valve 10 is interposed in a pipeline 11 dircting the working oil to the working chamber 5 by an oil-pressure pump 9, which is controlled by a controller 13 by which detected signal C from an output shaft revolving number detector 12 is compared with its target signal D, and then a switch signal F according to a deviation between them is supplied to the oil pressure switch valve 10.
