Low-pressure valve |
| abstract |
A low-pressure valve enabling precise control of a fluid flow rate through the valve during cyclical operation of the valve. The valve is useful for controlling air delivery to a patient as part of a portable ventilator. The valve comprises a housing having an inlet 16 and two outlets 18 and 20 . A wiper plate 22 and an orifice plate 24 are disposed inside of the housing. Transverse movement of the wiper plate 22 relative to the orifice plate 24 , powered for example by a servomotor 34 , simultaneously and alternatively covers and uncovers various openings 26 in the orifice plate 24 . The total flow through the valve is thereby divided between the two outlets 78 and 20. |
