1. a rotating fluid device comprises a housing (11) that limits a fluid input (25) and a fluid output (27);

  • A rotating fluid mobile mechanism (15) that comprises an output element that has track or rotatablely move (31), described mechanism comprise a braking part (99) that is extended back vertically by described output element (31);

    Braking part (99) operationally interacts with described output element (31), thereby the braking motion of described braking part (99) just makes described output element (31) brake;

    Described housing (11,21) limits one and is as general as columniform arrester (71), and a piston element (75) is set in described arrester (71), and described piston element (75) can be mobile between biasing spring (105) effect second engagement positio down that first retracted position under the fluid pressure action in described arrester (71) and are being set to engage with the rear side (107) of described piston element (75);

    It is characterized in that;

    (a) described housing (11,21) limits one group of internal thread (85) with the adjacent setting of described piston element (75);

    (b) one has a closure member (87) that comprises the front surface of the spring seat (115) that is used for described biasing spring (105);

    With(c) described closure member (87) defines one group of outside thread (88) with described one group of internal thread (85) threaded joint, the axial position of described thus closure member (87) and described spring seat (115) can be corresponding to the rotation of described closure member (87) and is adjusted, to change the load holding torque of described braking part (91).
