Abstract
Engine pre-engage starters formed of compactly interfit sections featuring a universally applicable high speed turbine rotor, formed preferably of nylon based plastic, the body of which is distinguished by low tensile strength, high impact resistance, radial growth and adjustment in correspondence with the speed of its rotation, minimal evidence of stress and no material fracture even under the most adverse conditions of its use and a structural composition which reduces to powder form when subjected to friction at such time the speed of its rotation reaches and exceeds a prescribed limit. The rotor is so connected with its power transmission shaft to position beyond and form an axial extension of one end thereof. The rotor is contained by a peripherally encompassing structurally complementary plastic buffer which enhances its fail safe properties. Optionally, the starter housing may be provided with discretely positioned sound deadening inserts. The starters illustrated each feature a highly simplified control system operative to effect a substantially instantaneous shutdown thereof when the speed of rotation of the rotor exceeds a predetermined limit. At the same time the nature …
