ABSTRACT:
The invention relates to a fluid valve, in particular for use as a throttle valve in an internal combustion engine. The valve has a flow path (25) for the air (26) defined by a tube having a flexible wall (14) which separates the tube from an adjacent chamber (36), so that a change in the pressure within the chamber (36) deforms the flexible wall (14) and thus causes a change in the internal cross-section of the passage (25). When the valve is in its closed position, air can still flow through an air bypass passage (46).
