Considering the forces of friction and gravitation, local component of inertial force there was obtained the analytical solution for linearized problem of propagation of pressure disturbances and the liquid rate in the elementary area of the pipeline with air chamber which were generated by the partial or full stopping of withdrawal. The air chamber was taken into account according to I.A. Charniy. The equations related to static pressure and flow rate were derived from N.E. Jukovskiy equations, and were solved by the variables separation method the for mixed-boundary conditions. Based on the obtained solution there was conducted a computational experiment. The obtained results let us to reveal the features of transformation of pressure and rate disturbances depending on different parameters such as the volume of the air chamber.
