Embodiment Construction
[0010] Referring to the drawings, in which like numerals indicate like or corresponding parts in the various figures, there can be seen in FIG. 1 a schematic representation of a tank or container 10 containing hydraulic fluid. The transmission controls the pump 12 to draw fluid from the container 10 through the filter assembly 14 . Pump 12 outputs pressurized hydraulic fluid to transmission system 16 . The maximum pressure at the pump output port is determined by the pressure regulator valve 18 which sends excess pump flow to the filter 14 . In accordance with a preferred embodiment of the present invention, the fluid first meets the transmission lubrication and pressure requirements, then the torque converter pressure requirements, then provides some lubrication and cooling, after which excess fluid is returned to the filter assembly 14 .
[0011] Lubrication flow and leakage fluid in the transmission system 16 returns to the container 10 through passages such as 20 . Exces...
