<p>The pneumatic spring valve regulates the air pressure for the pneumatic suspension of motor vehicles and/or trailers in relation to the loading. The valve control piston has two conical pistons (15, 16) connected to a common piston rod (14). The piston tapers are arranged in opposite direction so that their narrower parts face each other over a distance. These pistons have cylindrical parts at their larger ends and the conical surfaces are in contact with the inlet and outlet orifices of the valve. The cylindrical parts form chambers (21) vented by the inlet and outlet valve parts.</p> |
