Abstract (en)
A decompression device of an internal combustion engine having a release lever (18) pivotally supported on a cam driven gear (15d) and urged by centrifugal force to swing radially outwardly, when the cam driven gear rotates, so as to permit a valve tappet (17) to return into normal contact with a valve cam (15e). During a start-up compression stroke, the release lever (18) swings radially inwardly by a spring (20) to contact and move the tappet (17) to a position for partially opening the valve for decompression. The release lever (18) has a pivot shaft (18a) fixed perpendicularly to the lever and rotatably passing through the cam driven gear (15d). The pivot shaft (18d) has a decompression cam (18b) for allowing the tappet to return to a normal position. The spring (20) is a coil torsion spring fitted loosely around the pivot shaft (18a).
