    • In a fluid coupling wherein a turbine shell is welded to a turbine hub, it is necessary to take care of the strength of the welded portion because the turbine shell is displaced toward the pump blade as the torque thereof is transmitted. A fluid coupling (10) according to the present invention is provided with an input-side rotary constituent (A) including a pump blade (18), to which is attached an input member, and an output-side rotary constituent (B) including a turbine shell (22), to which is attached a turbine blade (21) opposed to the pump blade (18), and a turbine hub, to which is coupled an output member (1), the turbine hub (15) being welded to an inner peripheral portion of the turbine shell (22), wherein the turbine shell (22) and the turbine hub (15) have contact surfaces (23, 24), respectively, extending along a rotational axis (10a) of the fluid coupling (10), and a joint portion (14) is formed by the welding on the contact surfaces (23, 24) closer to the pump blade (18).
    • 在涡轮壳体被焊接到涡轮机轮毂的流体联轴器中,由于涡轮机壳随着其扭矩传递而朝向泵叶片移位,所以需要注意焊接部分的强度。 根据本发明的流体联轴器(10)设置有输入侧旋转构件(A),其包括附接有输入构件的泵叶片(18)和输出侧旋转构件(B),输出侧旋转构件 与涡轮机叶片(18)相对的涡轮机叶片(21)与涡轮机壳体(22)相连接,涡轮机壳体(22)与涡轮机毂相连接,涡轮机毂联接在输出构件(1)上,所述涡轮机毂(15)被焊接 到涡轮壳体(22)的内周边部分,其中涡轮壳体(22)和涡轮机轮毂(15)分别具有沿着流体联接器的旋转轴线(10a)延伸的接触表面(23,24) (10),并且通过焊接在更靠近泵叶片(18)的接触表面(23,24)上形成接合部分(14)。

    • A hydraulic control unit provided with oil pumps includes a first oil discharging outlet and a second oil discharging outlet, a high pressure route connected with the first oil discharging outlet, a medium pressure route with an oil pressure therein being lower than that in the high pressure route, a low pressure route with an oil pressure therein being lower than that in the medium pressure route, and a connection mode switching mechanism for selectively connecting a second oil discharging outlet with the high pressure route, the medium pressure route or the low pressure route. The connection mode switching mechanism includes a changeover valve selectively connecting the second oil discharging outlet with the medium pressure route or the low pressure route; and a changeover valve controlling device connecting the second oil discharging outlet with any of the medium pressure route and the low pressure route. The hydraulic control unit can minimize drive loss of an oil pump.
