PCT No. PCT/AU89/00275 Sec. 371 Date Feb. 20, 1991 Sec. 102(e) Date Feb. 20, 1991 PCT Filed Jun. 27, 1989 PCT Pub. No. WO90/00218 PCT Pub. Date Jan. 11, 1990.A radial cylinder machine comprises a number of equispaced lobed shafts (7) which orbit about the central machine axis inwardly of the pistons (13). The lobed shafts (70) also rotate about their individual axes by virtue of planetary pinions on each shaft (7) meshing with a fixed ring gear. The orbiting and rotating lobes (9) act as cams on the inward faces of the pistons (13) whereby there is inter-conversion of reciprocatory motion of the pistons (13) and rotary motion of the lobed shafts (7). The lobed shafts (7) are mounted on a carrier fixed to a central axis input/output shaft whereby torque may be transferred permitting the machine to act as an engine or pump. There is also disclosed a means of maintaining contact between the pistons (13) and the lobes (9).
