Pneumatic suspension, especially for rail vehicles, has pneumatic cushion with low pressure volume connected to additional vessel with high pressure gas volume by means of pressure intensifier consisting of stepped piston

摘要

The suspension's pneumatic cushion which includes the volume(1) under low pressure is connected to an additional vessel which includes the gas volume(5) under high pressure by means of a pressure intensifier consisting of a stepped piston, the larger piston face(2) of which faces the low pressure volume and its smaller face(3) facing the high pressure volume. The ratio of the larger and smaller piston faces is reciprocal to the low and high pressures.
