DILUTED-FLUID DISPENSING DEVICE WITH PRESSURE-COMPENSATING PASSIVE VALVE |
摘要 |
Herein is disclosed a diluted-fluid dispensing device that operates on the venturi principle to mix a concentrate with a diluent. A pressure-compensating passive valve is provided in a fluid passage of the device through which diluent flows, in order to enhance the precision of the dilution over a range of pressure and/or flowrate at which diluent may be supplied to the device. The passive valve may be placed in proximity to the diluent inlet of the device. The passive valve may be a self-actuating valve. |
