Improvements in diaphragm pumps |
摘要 |
A novel changeover mechanism for a compressed air driven double diaphragm pump comprises a shaft slidably mounted through aligned apertures in opposing surfaces of the twin diaphragm chambers. At the center of the shaft between the two diaphragm chambers is provided an annular notch in to which is located an arm extending from a U shaped frame. The U shaped frame is pivotally mounted atop a valve plate which includes multiple ports. |
