<p>A pressure limiting valve (1), particularly for medical assisted-ventilation equipment, comprising a hollow body (2) provided with an intake port (3) and a discharge port (4) for a fluid and a flow control element (8) for controlling the intake port (3), a flat spring (7) which is accommodated within the hollow body (2), is arranged substantially at right angles to the input stream of the fluid and has at least one end which is rigidly associated with the hollow body (2) and rigidly supports the flow control element (8), the flat spring (7) being flexible in the direction in which the flow control element (8) moves away from the intake port (3) at a presettable threshold value of the pressure applied by the fluid entering from the intake port (3).</p> |
