Definitions
- a gear is rigidly formed on the impeller and a starter motor is coupled to the gear on the impeller via means during engine starting and is decoupled after theengine has started and has reached a speed of rotation v greater than the motor.
- Said means comprises a pinion which travels on a threaded shaft driven by the starter motor between a first position in engagement with the gear on the impeller and a second position but of engagement with said gear.
- FIGURE of the drawing is a longitudinal cross section taken through the apparatus according to the invention.
- numeral I denotes an engine cylinder block
- numeral 2 denotes a crankshaft of the engine-An impeller 3 is fixed to one end of crankshaft Z
- numeral 4 denotes the blades of the impeller.
- the impeller rotates in an impeller chamber 5, surrounding the impeller 3.
- the starting gear 13 is rotated and the-engine is started.
- the movable pinion I2 is in turn-rotated by the starting gear 13 so as to be at a higher speed than the screw l1, whereby the pinion 12 is moved to the left and is separated from the starting gear 13 to return to its original inoperative position.
- the engine cooling impeller 3 is attached to the starting gear 13 so as to be utilized as a starting mechanism, so that there is brought about the advantage that the construction can be simplified.
- the impeller housing is such that mud, dust or the like is prevented from entry therein.
- the starting parts, e.g. gears and the like are provided within the impeller chamber 5 as such, so that there is the advantage that these arts are in a clean environment and remain reliable in operaron andare hIgh in durability.
- the pressure at that portion behind the blade 4 in the impeller chamber 5 is higher than atmospheric pressure, so that even if there is a small gap between the starter motor 9 and the rear wall surface 8, contaminated external dirty air will not enter the impeller chamber 5, but rather the air within the impeller chamber 5 leaks slightly to the outside through-such gap.
- Numeral 6 denotes a suction opening in the front surface of chamber 5 and number 7 denotes an air conduit pipe for supv plying the air under the action of blades 4 to the engine, the
- Numeral 8 denotes the rear wall surface of the impeller chamber 5. The construction described to this point is conventional.
- a starter motor 9. for engine starting is attached. to the outside of the rear wall surface 8, and a screw 11 at the end of a spindle l0 projects into the interior of the impeller chamber 5,
- the starter motor 9 is started to rotate the screw 1 l.
- the movable pinion 12 is then brought, owing to its own inertia, in relative rotation to the screw 11 to move to the right, and is then 'stopped in its rightward movement by striking against a I stopper 14 after meshing with the starting gear 13, whereby detachably engageable cordingly, it is advantageous that the starter motor 9 is not required to'be afi'rxed in airtight relation to the rear wall surface 8 and thus the attaching of the starter motor 9 can be simplified.
- an air-cooled engine having a crankshaft; an impeller connected to said crankshaft and adapted to convey cooling air thereto;'a chamber; said impeller being rotatably mounted in said chamber, said chamber having a front air inlet-portion and a rear air outlet portion providing a region of generallyim creased atmospheric pressure during rotation of said impeller; an engine starting apparatus comprising a starter'motor; gear means on said impeller; and means coupling said starter motor' and gear means for driving the impeller from the motor when the engine is being started and for decoupling the impeller and motor after the engine has startedand the impeller rotates at a speed greater than the motor, said gear means and said coupling means being positioned in said chamber in the region of increased atmospheric pressure so as to prevent contamination thereof when subjected to passage of cooling air through said chamber.
- said means for coupling said starter motor and gear means comprises a threaded shaft driven by said motor, and a pinion in threaded engagement with said shaft and displaceable therealong between a first position in engagement with said gear and a second position out of engagement with said gear.
- An engine as claimed in claim 2 comprising stop means mounted on said shaft for limiting displacementof the pinion when the pinion reaches its impeller driving position.
