1. An actuating device, comprising:
an actuator having at least one driving portion;
a stationary portion provided in a rectangular housing and at an arbitrary position along the actuator such that the driving portion forms a first driving portion on one side of the driving portion and a second driving portion on an opposite side of the driving portion, the actuating device being characterized in that by adjusting the stationary portion in position to make a first length of the first driving portion and a second length of the second driving portion equal to or different from each other, the first driving portion and the second driving portion are able to be provided with a same actuating ability or each with a different actuating ability;
wherein the first driving portion is an elongated member for providing a moment arm and has a first driving end, and the second driving portion is also an elongate member for providing a moment arm and has a second driving end;
a first valve controller held in the housing in a rotatable manner by a pin and having:
a first force-receiving end having a side corresponding to the first driving end in order for the first force-receiving end to be driven by the first driving end;
a first valve-controlling end for controlling opening and closing of a first port of the housing; and
a first restoring spring provided between an opposite side of the first force-receiving end and the housing; and
a second valve controller held in the housing in a rotatable manner by a pin and having:
a second force-receiving end having a side corresponding to the second driving end in order for the second force-receiving end to be driven by the second driving end;
a second valve-controlling end for controlling opening and closing of a second port of the housing; and
a second restoring spring provided between an opposite side of the second force-receiving end and the housing.
