ABSTRACT:
A pump unit includes a first plunger pump including a suction port arranged at an end of the first pump distant from a camshaft and a discharge port arranged at another end thereof near the camshaft, and a plunger second pump including a suction port arranged at an end of the second pump near the camshaft and a discharge port arranged at another end thereof distant from the camshaft. The first and second pumps are arranged in parallel with each other along the camshaft so that plungers of the first and second pumps contact corresponding cams of the camshaft. The first and second pumps are connected in series so that the discharge port of the first pump communicates with the suction port of the second pump.
