PURPOSE:To make a fluid joint controller in small size by adjusting a flow control valve, installed at the front part of an impeller, on the basis of the output formed by combination of the output revolutional speed signal with discharge pressure signal or manual operation signal. CONSTITUTION:A flow control valve 54 is installed at the front part of an impeller 46. A fulcrum rod 20 to couple a spool 23, to output the output revolutional speed signal, with No.1 floating lever 16, to output either a signal in response to the discharge pressure of a pump 42 or a manual operation signal selectively, shall be coupled with No.2 floating lever 21, which is coupled in turn with the abovementioned flow control valve 54. Thereby a control device 44 is divided into a selection mechanism 16 to select one of the discharge pressure signal and manual operation signal and a combination mechanism 21 to combine the selected signal from said selection mechanism 16 with the output revolutional speed signal, and they are arranged three-dimensionally. Thus the construction can be made small. |
