Double diaphragm operated reversing valve pump

A reciprocating fluid pump has a dual piston element and dual diaphragms in fluid communication therewith. Full movement of the dual piston element in either direction of movement causes movement of a pilot valve which simultaneously vents a first working chamber located in the direction of movement...

Beschreibung
Zusammenfassung:	A reciprocating fluid pump has a dual piston element and dual diaphragms in fluid communication therewith. Full movement of the dual piston element in either direction of movement causes movement of a pilot valve which simultaneously vents a first working chamber located in the direction of movement of the dual piston element and occasions reciprocating movement of the dual diaphragms, thereby directing a pump power medium to a second working chamber to cause movement of the dual piston element in the opposite direction.
