Abstract
A valve to control the flow of pressurized fluids, such as medical or industrial gases, consists of a body with an internal fluid distribution circuit, comprising a fluid inlet, a fluid outlet, and a internal fluid passage connecting them. Fluid flow can be controlled by an operator manually actuating a lever. This lever can move between at least three stable positions that are angularly staggered in relation to each other. In the rest position, the lever is fixed and solidly connected to the body of the valve, and there is zero fluid flow in the internal fluid passage. In the intermediary released position, the lever is disconnected from the body, but the fluid flow remains zero. In the active position, the lever is disconnected from the body, and fluid flows thorough the internal fluid passage at a non-zero rate. Application also to gas cylinders equipped with such valves.
