Rotary to reciprocating motion converting piston - has two axially extending tooth racks alternately meshing with piston on rotating shaft with teeth over 40 per cent of circumference only

摘要

The mechanism is for converting rotation into reciprocating motion or vice versa. The reciprocating motion may be carried out by a piston. - The rotating shaft is arranged with its axis intersecting the piston axis and carries a pinion with gear teeth over 40% only of its perimeter. The piston carries a piston rod consisting of two parallel axially extending tooth racks which alternately mesh with the teeth of the pinion as this rotates.
