Abstract
PURPOSE: To facilitate the speed adjustment and miniaturize the device by controlling an electromagnetic valve which adjusts an oil stream from a hydraulic pump and a valve which by-passes the electromagnetic valve, in correspondence to the deviation between the rotating speed of an output shaft and the set temperature thereof.
CONSTITUTION: The constant speed control device comprises a control circuit 24 which compares the output of a pickup 22 which detects the rotational speed of the output shaft with the output of a speed setter 25, and delivers a signal corresponding to the deviation between both speeds to a pressure regulating electromagnetic valve 20. Further, there is provided a by-pass valve 21 which automatically by-passes the electromagnetic valve 20 when the deviation becomes large. The by-pass valve 21 leads a fluid pressure adjusted by the electromagnetic valve 20 to clutches 6 and 7 when the deviation is smaller than the predetermined value to control the clutch oil pressure in a semiclutched state. On the other hand, when the deviation is larger than the predetermined value, the hydraulic pump 2 is connected to the clutches 6 and 7 to put the clutches 6 and 7 in a directly connected state.
