The stroke lengths of the fluid pumps (AA and AB) can
be adjusted to select the ratio. The frame (AN) has three

mechanism at the top of the pump, which allows for
positioning of the pump at any required position. This
allows for a a range of ratio settings between the first
and last settings on the pump drive link.
