Abstract
A manual starter crank has an integrated safety device providing protection against backfiring during starting of an internal combustion engine. The manual starter crank has a starter shaft which, when turning in a starting direction, engages the free end of a cam shaft of the internal combustion engine. The safety device is integrated into the casing of the manual starter crank and includes a ratchet with a pivot axis which is approximately parallel to the starter shaft. In the engaged position of the ratchet, a free end thereof engages an abutment surface on the starter shaft, whereby the manual starter crank is connected in torque transmitting relation with the engine cam shaft when the crank is turned in a starting direction. The safety device includes a disengaging bushing surrounding the starter shaft and which is mounted on a bearing support by a one-way clutch and presents a disengaging pin in the path of movement of the ratchet. The disengaging pin cooperates with the ratchet to move it to a disengaged position during backfiring of the engine.
