<p>A device for adjusting and throttling the flow-rate of a fluid, particularly medical oxygen and compressed gases in general, which comprises a valve body (2) which defines an input port (3) and an output port (4) for a fluid at high pressure. The input port (3) is controlled by a high-pressure flow control element (5). There is also an input duct (8) for a low-pressure fluid which is connected to a rotating body (15) with a control port (16) which can be arranged at the calibrated holes (12) provided in an adjustment disk (11) and connected to at least one output duct (18). There is also a single actuation handwheel (35) which drives the high-pressure flow control element (5) and the rotating body (15).</p> |
