STRUCTURE AND FUNCTION, MAINTENANCE STANDARD

TORQUE CONVERTER

Flow of oil •

•

The oil passes through the main relief valve and its pressure is adjusted by the torque converter relief valve so that it is less than the set pressure. It then enters inlet port A, passes through the passage in stator shaft (8) and guide (9), and flows to pump (6). The oil is given centrifugal force by pump (6). It then enters turbine (4) and transmits the energy of the oil to turbine (4). The oil from turbine (4) is sent to stator (11), and enters pump (6) again. However, part of the oil passes between turbine (4) and stator shaft (8), and is sent through outlet port B to the cooler.
