AUTOMATIC SHUTOFF DISPENSING NOZZLE VENTURI |
摘要 |
A continuous groove is formed in the conical bore of a variable venturi body to increase the area in which the liquid flowing therethrough can expand to produce an enlarged low-pressure area. This enlarged low-pressure area enables a diaphragm to be moved to close a main valve even when the flow rate through the venturi is as low as one gallon per minute.
