APPARATUS FOR MIXING GASES
A method and apparatus for mixing gases from separate pressurized gas circuits for use in applications such as medical respirators. The pressures of the gases in the two circuits are accurately balanced to provide an equal pressure drop across a differential mixing valve for precise control of the r...

| description | A method and apparatus for mixing gases from separate pressurized gas circuits for use in applications such as medical respirators. The pressures of the gases in the two circuits are accurately balanced to provide an equal pressure drop across a differential mixing valve for precise control of the ratio of flow rates of the gases being mixed. In one embodiment, a double state pressure balancing mechanism is provided for increased accuracy of pressure balance. |
