In these types of engine operating with compressed air and comprising a high-pressure compressed air tank, the compressed air contained at high pressure in the tank has to be expanded but, as the tank is drained, the air pressure is reduced to a stable intermediary pressure known as the final use pressure in a buffer capacity prior to being used in the master cylinder(s). The conventional, well-known gate and spring pressure reducers have extremely low ***flowrates***, and their use for this application requires extremely heavy-duty, inefficient appliances; plus the humidity in the air cooled during decompression is highly likely to cause them to ice up.
The distribution system according to the invention which uses a cam, rocker arm and rocker arm rod assembly, on the one hand, acts as a **variable flow*** pressure reducer, as a simplified camshaft-less control and as the drive system (chain, belt, pinion gears), and on the other hand, adjusts the lifting of the valve and the angular spread of the aforesaid opening from maximum lifting through to zero lifting thereby making it possible to ensure that the ***filling and/or draining flowrate** of the cylinder in question is controlled and that the accelerator butterfly control is advantageously replaced. It is characterized in that the air supply in the final use buffer capacity and the supply to the cylinders are ensured by pilot valves
