      A detailed generation was performed to prod ice the characteristic series coefficients used to obtain the control laws for unshocked unlimited compression of gas layers. The field of application for expansion obtained is studied. It is found, that only two first terms of a series have no singularities. It is shown, that truncated series, retaining regularity can be used as a solution. The law of a piston movement up to the focusing moment is obtained. The integral curve behaviour is studied for normal difference equation describing the piston movement law. The correctness of approximations obtained is verified by calculations, using characteristic method and illustrated by graphs and tables.
