摘要

The pump works on an opposed piston concept with two pistons in a cylinder working in opposite directions. The power transmission to the pistons takes place through two crankshafts with connecting rods. The synchronizing of the two pistons is through a synchronizing gear which also functions as the drive transmitter of the machine.
