Connecting rod 7 is connected by turning pairs C and B to piston 3 of the power cylinder and to lever 4, linked to the flap and turning about fixed axis A. Upon a change in the pressure of the air at the supercharger output, which is connected to chamber a, the pressure of the liquid in bellows 1 is changed, leading to deformation of the bellows and the shifting of valve spool 2. At this, fluid delivered to the valve is directed to one of the ends of the power cylinder, moving piston 3. Fluid from the exhaust end of the cylinder is drained through the valve to the tank. Turning, lever 4 changes the position of the flap at the supercharger input, thereby maintaining constant pressure at the supercharger output. The regulator is set to a definite pressure by turning pinion 6 which meshes with rack 5 of the rod of bellows 1.
