In response to the growing energy consumption requirements of fluid systems, resulting from rising energy costs and environmental requirements, vehicle systems are also undergoing changes. Work on reducing the energy consumption of systems is carried out in a wide scope and to practically all power transmission systems in vehicles, including the pneumatic circuits of commercial vehicles. One of the results of this work is the development of an innovative system that allows for the recuperation of the pressurized fluid medium in the pneumatic brake and suspension circuits, which directly translates into a reduction in energy consumption. The newly proposed solution aims to partially recuperate the energy and medium while minimizing dynamic response impact and system complexity. This is achieved by the connection between the recuperation reservoir and environment, with the no-return valve between and utilizing backpressure caused by noise reduction components on exhaust on the system. Such usage of free flow of least resistance is expected to provide a means of energy re-usage in time-sensitive applications such as pneumatic brake circuits. The article presents a description of the solution together with the scientific foundations underlying its development. In addition, a comparison of the energy balances of the classic and the new system is presented, the results of which were the basis for the decision to undertake further work on the described solution.
