Construction –
This mechanism is an inversion of Single slider crank chain, obtained by fixing the crank .It has three turning pairs & one Sliding pair.As shown in diagram it has 5 or 7 cylinders and connecting rods of all pistons are connected to one point which is another end of crank. In this mechanism crank itself is fixed.
Working –
As pistons start reciprocating inside cylinders, whole frame starts rotating about fixed pt 'O' the crank remains at its place. The rotation of frame causes suction, comp,expansion & exhaust strokes in different cylinders at same time.
Application –
It was used in airplane engines in past, now a days it is not used.
