Abstract: A governor valve for a hydraulic controller in an automatic transmission, which is disclosed herein, comprises an adapter having a line pressure supply bore made therethrough, a cylindrical governor rotary shaft loosely fitted into the adapter sleeve and having a line pressure supply port made therein, the port including notches intersecting the axis at right angles, a centrifugal weight mounted on one end of the governor rotary shaft and having a return spring, and a spool adapted to slide within the governor rotary shaft with the weight being urged against one end thereof. In this governor valve, there are provided dirt and dust collecting means for preventing dirt and dust separated by a centrifugal action from collecting in the line pressure supply port during the stoppage of the governor rotary shaft so as to make the shaft stick.

Abstract: An internal-gear pump with a partition plate, comprising: an arcuate chamfer formed at an inner edge of an end face of the partition plate rotationally opposing an inner gear of the pump and having a curvature at least greater than that of tooth tip edges of the inner gear.

Abstract: A governor hydraulic pressure supply apparatus is provided for use with the vehicle automatic transmission system and includes a governor valve mounted on a rotary output shaft from the automatic transmission, the output shaft having an internal input fluid line for supplying a line pressure to the governor valve and an internal output fluid line receiving a governor pressure from the governor valve, and the governor valve body having an internal input fluid line to be connected to the input line from the output shaft and an internal governor pressure output line to be connected to the output line in the shaft, wherein the joined faces between the governor valve and output shaft at which the fluid lines are respectively connected with each other are brought in close contact with each other by tightening the two element by means of a tightening bolt adjacent to the joined faces, thereby preventing fluid leak from the faces.
