ABSTRACT:
This invention relates to reciprocating piston machines which use the crankcase for pumping air or charge. The connecting rod with extension partitions the interior of the crankcase including the lower cylinder into two varying volumes during a portion of each revolution of the crankshaft. A unique feature is that the designer can choose the capacity of the crankcase pump independent of other significant design parameters such as the ratio length of connecting rod/stroke and the ratio stroke/bore.
