OMEGA TYPE PUMP

摘要

A piston (3) with cylindrical blades remains constantly parallel to itself as its center rotates on a circle thanks to two additional free cranks (10) with throw equal to that of main driving crankshaft (4, 5, 6). Cylindrical blades on the casing (1) cooperate with the piston blades to form the pump. A piston not extended beyond its outer blade results in improved sealing, better ports, reduced dimensions, diminution of friction and lower weight. Apertures through the inner hub of the piston permit the connection of the casing parts with means (18) passing through them, supplying stiffness and precision of the assembly as well as sealing efficiency between the chambers.
