ABSTRACT:
An actuation device for a tachometer adapted to transmit the revolutions of an engine crankshaft to the tachometer, wherein the oil pump of the engine is utilized as a speed reducing mechanism for transmitting the revolutions of the engine crankshaft to the tachometer after the engine speed is reduced. A cable connected at one end to the plunger of the oil pump whose speed is reduced by means of a gearing is connected at the other end to the tachometer. Thus, by utilizing the oil pump, it is possible to transmit the revolutions of the engine crankshaft to the tachometer without requiring a speed reducing mechanism provided exclusively for the tachometer.
