ABSTRACT:
A centrifugally-responsive compression release apparatus relieves compression in more than one cylinder of an internal combustion engine during starting. The compression release apparatus utilizes a centrifugally-responsive flyweight, a single shaft operable by the flyweight, and one or more lift members movable by the shaft and engageable with one or more valve operating devices. The compression release apparatus may employ a single lift member that is engageable with two valve operating devices upon rotation of the shaft, or alternatively, a pair of lift members each engageable with a distinct valve operating device. Thus, the compression release apparatus is particularly adaptable to reducing compression in two cylinders of a V-twin engine, but may be adapted to reducing compression in an engine having more than two cylinders.
