4 should produce greater torque due to its greater leverage fig 5 and fig 6 depict the basic core of the machine which is common to both mechanical arrangements the cylinders 17 are spaced around the body 8 at 45 u00b0 intervals in order to conserve space and reduce the length of the body 8 in this way eight cylinders 17 can be accomodated in a band about the body 8 only a few inches in width four elliptical plates 15 or cams 25 are needed to operate eight pistons 13 the inner core consists of a tubular section inside a larger tubular section 8 with the cylinders 17 spiraled around and between the two sections of tubing at 45 u00b0 intervals like spokes in a wheel any reasonable number of cylinders is possible by simply continuing to space them about the body 8 like the spiral stripe around a barber pole fig 7 depicts a series of cams as used in arrangement 2 illustrating the spacing and angle of the cams 25 about the displacer shaft 16 fig 8 is an exploded view of a series of plates 15 as used in arrangement 1 showing their angles with relation to each other fig.
