<p>PCT No. PCT/EE96/00003 Sec. 371 Date Mar. 1, 1999 Sec. 102(e) Date Mar. 1, 1999 PCT Filed Dec. 13, 1996 PCT Pub. No. WO98/26182 PCT Pub. Date Jun. 18, 1998This invention may find use in applications such as pumps and other machines, it solves the problem of reduction of hydrodynamic resistance multiply and increases the capacity. The offered mechanim comprises of disc-shaped housing (1) with through hole (2), which is overlapped by mobile parts of rotary-piston group. Four chambers (6), formed by rotor (5) and pistons (11, 12), move in a circle inside the housing hole (2) in the plane of axle of the hole and run alternately along two sides of the housing. On running along one side they increase their volume, and along the other they reduce it, pumping over fluid through the said hole (2) in the housing. A rotary-piston group kinematically represents a modified Hooke joint. Shafts (4) are positioned at an angle. Sleeves of forks are changed into single arc-shaped half-sleeves, which are located directly on the shafts (one sleeve on each shaft). Cruciform has a spherical shape with two intersected circular canals and functionally the cruciform represents a rotor of the rotary-piston mechanism. Half-sleeves of shafts, located in the cruciform canals, functionally represent doubled pistons (11, 12). Inner surface of the through hole (2) in the housing and outer surface of members of the rotary-piston group (5, 11, 12) have spherical shape.</p> |
