ABSTRACT:
A fluid flow control system for connecting a source of pressurized fluid with a region of varying pressure, comprises a fluid supply duct having an inlet end connectable to the pressure source end and an outlet end connectable to the region of varying pressure, a vent duct disposed between the inlet and outlet ends, and a vent valve sensitive to change in pressure within the supply duct and operable so as to control the escape of fluid from the supply duct. The vent valve preferably comprises a flexible wall member of hollow, inflatable form. In operation of the system, a relatively small amount of fluid is allowed to escape when pressure at or adjacent the outlet end of the supply duct is substantially less than that at or adjacent the inlet end thereof, and a relatively large amount of fluid is allowed to escape when the pressure differential is reversed. The system is particularly useful as a "ride" control for gas-cushion vehicles operating over rough ground or water.
