ABSTRACT:
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.
