Abstract
An injection timing control device for use in a distributor-type fuel injection pump for internal combustion engines, which comprises: first and second hydraulic actuatable elements adapted to be actuated by a fluid pressure proportional to engine r. p. m., the second element having a larger pressure applying area than the first element and disposed on an extension of the axis of the first element; a first spring interposed between the first and second elements for urging the elements in opposite directions to each other; a second spring for urging the second element in an opposite direction to the first element; means for limiting displacement of the second element toward the first element; and means coupling the first and second elements for relative movement thereof within a limited distance. The elements and springs are so designed and arranged that the first element is displaced in an injection-timing-advancing direction during starting of an associated engine, while during the regular operation of the engine an ordinary timing advancing operation is carried out.
