초록

This invention provides a double-acting, double diaphragm pump particularly for fluids such as chemical compounds. The pump employs adjustable disk members mounted on a reciprocable rod connecting and actuating the diaphragms. These disks alternately engage the extending shaft of a pilot valve to move the valve and redirect the flow of pressurized fluid therethrough. The pressurized fluid behind the diaphragm is now caused to flow to a slide valve and cause it to be moved to an opposite limit. The slide valve is cycled by the pilot valves as the disks on...
