Abstract
IN A 4 STROKE CYCLE INTERNAL COMBUSTION ENGINE (I) HAVING INTAKE AND EXHAUST VALVES (9, 10) OPENED AND CLOSED BY RESPECTIVE INTAKE AND EXHAUST CAMS (27,28) MADE INTEGRAL WITH A CAMSHAFT (13), THE ENGINE (1) HAS A DECOMPRESSION CAM (38) FITTED ON THE CAMSHAFT (13) SO AS TO ROTATE FREELY. A ONE-WAY CLUTCH (29) IS FITTED ON THE CAMSHAFT (13) SO AS TO TRANSMIT REVERSE ROTATION TORQUE TO THE DECOMPRESSION CAM (38) ONLY WHEN THE CAMSHAFT (13) ROTATES IN REVERSE.A-TORQUE LIMITER (40) IS INSERTED BETWEEN THE DECOMPRESSION CAM (38) AND THE ONE-WAY CLUTCH (29). DECOMPRESSION CAM STOPPERS (42, 43) ARE PROVIDED ON A FIXED PORTION OF THE ENGINE (1) TO ENGAGE WITH AN ENGAGING SECTION (41) FORMED ON THE DECOMPRESSION CAM (38) FOR STOPPING ROTATION OF THE DECOMPRESSION CAM (38) AT RESPECTIVE POSITIONS IN NORMAL ROTATIONAL DIRECTION AND REVERSE ROTATIONAL DIRECTION.THE DECOMPRESSION CAM (38) HAS A CAM SECTION (38A) OF A LIFT HIGHER THAN A BASE CIRCLE OF THE EXHAUST CAM (28) AND LOWER THAN A MAXIMUM LIFT OF A CAM SECTION (28A) OF THE EXHAUST CAM (28).THE EXHAUST VALVE (10) IS NOT OPENED BY THE DECOMPRESSION CAM (38) WHEN THE CAMSHAFT (13) ROTATES NORMALLY AND THE DECOMPRESSION CAM STOPPER (43) ENGAGES WITH THE ENGAGING SECTION (41).THE ABOVE CONFIGURATION PROVIDES A DECOMPRESSION DEVICE WHICH IS SIMPLE IN CONSTRUCTION, SMALL-SIZED AND OF REDUCED COST.(FIG 1)
