摘要：
An electric pitch control apparatus for a variable-pitch propeller capable of properly controlling the pitch angle of the propeller blade in accordance with instantaneous operational conditions of the propeller and of effecting adjustment of the pitch angle of the propeller blade without any delay of a time in response to operation of the engine output lever for promptly coinciding an actual rotational number of the prime engine with a target rotational number.
