摘要： A liquid power transmission mechanism that is formed with a water turbine case or plurality of water turbine cases which are connected in series. The water turbine case is composed of blade wheel and water turbine and an outer housing. The outer housing forms a closed space by a housing body and a cover that is covered on the housing body. An axial hole is provided on the outer housing. The water turbine and the blade wheel are set in the closed space in series. The water turbine is a circular member and has a closed end and an open-mouthed end and is provided with a plurality of water inlets on its side wall. The blade wheel is composed of a main shaft and blades that arranged around the main shaft equably and is set in the water turbine. The main shaft is passing through the axial hole of the outer housing and there is a seal between the main shaft and the axial hole. The outer housing is provided with an inlet and an oulet in the radial direction respectively. The invention transmits the power with water in a closed circulating system so that it has low consumption and is environment friendly.

摘要： A turbine (1) has a control and regulating device with a pump (31) whose pressure varies as the square of the volume delivered by the pump or as the square of the rotational speed (n ) of the turbine (1). The hydraulic sequential piston arrangement comprising a preliminary control piston (41) and a control piston (5) for regulating the rotation speed of the turbine is supplied by a single pump (31). A compact, space-saving construction is thereby achieved. The turbine is suitable for use as a motor or drive in applications other than the generation of electricity, for example for cable winches.
