Stepped seal and bushing |
摘要 |
A torque converter has a lip seal abutting the torque converter impeller control pump drive hub. The drive hub is rotatably supported in a transmission housing. Oil from the drive hub side of the bushing passes through the bushing into a chamber sealed from atmosphere by the lip seal. The lip seal has a component rotatably sealing on a diameter greater than the drive hub diameter. The bushing, in one embodiment, has a control passage for exhausting a portion of the oil from the control pump side prior to reaching the chamber.
