	The scheme of "figure 8" storage ring based collider with zero-angle collision and electron and positron beams of equal currents, but different energies, is considered. In the common straight section both electrons and positrons moves in both directions. Outside the common straight section electrons and positrons circulates in separated loops (which "reflects" both beams to the common straight section). Therefore, in multibunch mode one can provide collision of four bunches and space charge compensation. One can say, that this configuration consists of electron storage ring with electron-electron collisions and the positron storage ring with positron-positron collisions. The new scheme may solve the well-known problem of separating instabilities of the four-beam compensation.
