When an engine stop control is executed while an automatic ratio shift portion is in a neutral state, a switching clutch is operated, so that a differential portion carrier of a differential portion planetary gear device that is linked to an engine, and a differential portion ring gear linked the automatic ratio shift portion are integrally rotated. Therefore, along with the engine stop control, the rotation speed of the rotating elements of the differential portion planetary gear device is reduced while the rotating elements are integrally rotated or substantially integrally rotated. Since the rotating elements are rotated integrally or substantially integrally, the high rotation speed of the differential portion ring gear linked to the automatic ratio shift portion, which tends to have a heightened rotation speed particularly during the neutral state, is prevented.

A speed limiting mechanisms for turbine-driven fluid distribution apparatus usable with compressible fluid such as compressed air and incompressible fluid such as water. Dynamic viscous damping of the turbine output power train is used to control the rotational speed of the turbine. This prevents overspeeding when the turbine is air driven, and also when the turbine is water driven, under abnormal conditions such as blockage of a bypass area designed to control the turbine speed by limiting flow to the turbine. The same mechanism can be used to impose a lower rotational speed in the turbine during normal operation in conjunction with a turbine optimized for lower speed operation to reduce the required gear reduction in the power train.
