A hydraulic pneumatic mechanical accumulator has a body that is divided into two chambers – a working one, filled with liquid, and a gas one. Between the inner surface of the body and the gas chamber a spring is placed, this is fixed at above on the body of the hydraulic accumulator, and at beneath – to the piston. Rigidity of the spring is chosen in such a way that rigidity of its compression exceeds compression pressure of the gas chamber at charged accumulator.
