Abstract: PCT No. PCT/NO87/00074 Sec. 371 Date Jul. 12, 1988 Sec. 102(e) Date Jul. 12, 1988 PCT Filed Nov. 16, 1987 PCT Pub. No. WO88/03986 PCT Pub. Date Jun. 2, 1988.A power conversion machine which is provided with a spherical housing (10) with piston construction (36,37) having two-double-acting pistons (36) turnable about a first axis (x-x) cooperating with a partition plate (40) tiltable about a second axis (z-z) for defining four work chambers with piston surfaces (36a, 36b) going forwards and backwards. The partition plate is connected forcibly to the piston construction so that the partition plate is subjected to a tilting movement while the piston construction is subjected to turning, without thereby turning the partition plate. Inlet openings and outlet openings which are placed one after the other in communication with the four work chambers, are opened and closed by a control effected by joint movement of the pistons and the partition plate.
