      An exact solution was derived for a pistion motion problem in a two polytropic gas mixture based on local pressure components equilibrium hypothesis assuming the absence of interaction forces due to the component velocity differencies. The shock wave is determined by a combination of two great jumps with different propagation velocities. For a rarefaction wave, two types of solution were obtained: those with full and partial component separation near the piston.
