Owing to the action of the liquid, rubber membrane 1, separating the hydraulic and pneumatic chambers, is bent upward, compressing the air and accumulating, in this manner, potential energy in the system. As the accumulator is put into operation, the potential energy of the compressed air is converted into kinetic energy. The accumulator is charged with air through valve 2. Liquid is admitted into the accumulator through check valve 3. Rigid washer 5 is provided to prevent membrane 1 from being squeezed into intake connection 4 when all the liquid is drained from the accumulator.
