QUICK ACCELERATION FLUID COUPLING

Japanese Patent JP3278281

B2

PURPOSE: To attain three-stage oil supply operation by parallelly providing supply oil lines for necessary supply oil amount relating to pump rotation of minimum, intermediate and maximum three stages, in the supply oil line to an operating chamber of a quick acceleration fluid coupling.
CONSTITUTION: In a stop condition before starting, operating oil is not supplied to an operating chamber R. In a minimum rotational speed condition of a driven shaft 4, a control valve f1 is opened, to close control valves f2, f3, and the operating oil is adjusted to a minimum oil amount by a minimum oil amount adjusting orifice (h), to generate a minimum rotational speed in the driven shaft 4. In an intermediate rotational speed condition of the driven shaft 4, the control valve f2 is opened, to close the control valves f1, f3, and the operating oil is adjusted to an intermediate oil amount by an intermediate oil amount adjusting orifice (i), to generate an intermediate rotational speed in the driven shaft 4. In a maximum rotational speed condition of the driven shaft 4, the control valve f3 is opened, to close the control valves f1, f2, and the operating oil is adjusted to a maximum oil amount by a maximum oil amount adjusting orifice (j), to generate a maximum rotational speed in the driven shaft 4.
