1. a fluid type power-transmission system, is characterized in that, has:

  • Fluid type power transmission device, it has the entrance and exit of working fluid, by making working fluid cycles carry out transferring power in inside;

    AndControl mechanism, it has the rotational speed feeler mechanism of the input rotational speed and the output rotational speed that detect described fluid type power transmission device, by being velocity ratio according to input rotational speed and the output rotational speed of described fluid type power transmission device and the ratio of described input rotational speed, adjust the pressure of the described working fluid of the described outlet of described fluid type power transmission device, control the pressure of the described working fluid of described entrance;

    Described control mechanism is along with the velocity ratio of described fluid type power transmission device declines, make the pressure rise of the described working fluid of the described outlet of described fluid type power transmission device, and adjust the rising of the pressure of the described working fluid of described outlet according to input rotational speed, so that the pressure of the described working fluid of the described entrance of described fluid type power transmission device does not reach below specified value.
