ABSTRACT:
A motion conversion system by which near 100% of a reciprocating motion, and a rotary motion, fluently converted from one to the other includes, a drive shaft (20), an intermediate circular element (22), externally teethed to near one-half of its circumference and an elongated element (24), having a pair of opposed internal teeth and internal curves, forming an elongated hollow to accommodate and constantly engage with the circular element. Due to their geometry and geometrical relationship, the three elements (20), (22) and (24), throughout the full cycle of reciprocating motion of the elongate element (24) and rotary motion of the drive shaft (20), remain fully engaged without interruption and with no further requirement for any additional gear engagement support. Simplicity, versatility, efficiency and easy to implement characteristics of the present invention, makes it the most practical arid effective motion conversion system of its kind. An ideal system that is fully applicable to most all cycle-operating parameters, including single or dual-pistons internal combustion engines, pumps and compressors, cycle-operating exercise equipment as in bicycles and virtually all instruments in which conversion of a reciprocating motion and a rotary motion, from one to the other, is required.
