Claims

[Scope of Claim for Utility Model Registration] In a compound pump of the type in which three or more pumps are driven by one engine, two or more pumps in the front row and one or more rear pumps drive the plurality of pumps. The front pump is arranged on the engine side, and the rear pump is connected to the front pump in series and back-to-back via a valve block. One suction port connected to the side, three or more discharge ports that communicate independently to the discharge side of each pump, and a space for accommodating a coupling that connects the drive shafts of the pumps in series. A dual-action pump characterized by:
