A valve for controlling the flow of a pressurized fluid, in particular a medical or industrial gas, a fluid inlet, a fluid outlet, and a internal fluid passage that connects them. A valve for controlling the fluid flow can prevent the circulation of a fluid in this passage, and an actuator utilizing a pivoting lever can be manually actuated by an operator. This lever pivots around a pivot point and can move between at least three stable, angularly staggered positions including a rest position where there is zero fluid flow in the internal fluid passage a intermediary released position where the fluid flow remains zero and an active position with fluid flowing thorough the internal fluid passage at a non-zero rate.

What is 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;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 axis and a pivot axis, said lever comprising a manipulating end and an active end;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, wherein said body is covered with a rigid external structure forming peripheral cladding for said body, said rigid external structure being secured to said body, and in that, in said rest position, said lever is held indirectly secured to the body by being fixed to said rigid external structure by way of a catching means.
