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.

The invention claimed is: 1. An apparatus for controlling the flow rate of a pressurized fluid, comprising:a) a body, said body comprising an internal fluid-distribution circuit, a fluid flow control means, and a manipulating means;b) said internal fluid-distribution circuit comprising a fluid inlet
The invention claimed is: 1. An apparatus for controlling the flow rate of a pressurized fluid, comprising:a) a body, said body comprising an internal fluid-distribution circuit, a fluid flow control means, and a manipulating means;b) said internal fluid-distribution circuit comprising a fluid inlet orifice, a fluid outlet orifice and an internal fluid passage fluidically connecting said fluid inlet orifice to said fluid outlet orifice, wherein said fluid inlet orifice is borne by a base of said body comprising a peripheral external screw thread having a screw thread axis and said body extends in a longitudinal direction along said screw thread axis;c) said fluid flow control means acting on said internal fluid passage to permit or prevent fluid from flowing along said passage between said fluid inlet orifice and said fluid outlet orifice;d) said manipulating means being actuated manually by an operator and collaborating directly or indirectly with said fluid flow control means to permit or to prevent said flowing of fluid along said passage, said manipulating means comprising a lever with a first axis pivoting about a pivot axis and able to move between at least three stable and angularly offset positions, said positions comprising a rest position, a liberating intermediate position, and an active position, said lever comprising a first leg extending angularly away from a second leg, said first leg terminating in a manipulating end and said second leg terminating in an active end, wherein said lever is configured such that when said lever is in said rest position said first leg extends along said body in said longitudinal direction;e) said rest position in which said lever is held, directly or indirectly, fixed and secured to said body and in which said fluid flow control means completely shut off said internal fluid passage so as to obtain a zero fluid flow rate in said internal fluid passage;f) said liberating intermediate position in which said first axis of said lever is offset by a positive and non-zero first angle with respect to said pivot axis of said lever in said rest position, in which position said lever is detached from said body and in which position said fluid flow control means completely shut off said internal fluid passage so as to provide a zero fluid flow rate in said internal fluid passage; andg) said active position in which said first axis of said lever is offset by a positive and non-zero second angle with respect to said first axis of said lever in said liberating intermediate position, in which position said lever is detached from said body and in which position said fluid flow control means no longer shut off said internal fluid passage so as to allow fluid to circulate at a non-zero flow rate along said internal fluid passage.
