The invention relates to a simple structure, easy to manufacture double cylinder in-line pump. It includes two cylinder in-line pump, oil group double cylinder camshaft inline pump pump body is provided with a cam mechanism with two sets of independent and Unicom cam cam mechanism; two groups of the eccentric wheel is fixed on the pump body of the cam shaft, the eccentric cam mechanism and the two groups the circular design of eccentric circle on the camshaft diameter in the opposite direction, the upper cam structure is also provided with a valve seat of the oil import share. The invention is characterized in that the two valves are commonly used as a valve seat; the upper end of the valve seat is processed with an oil valve cone surface; the lower end of the valve is processed into an oil inlet valve cone; the middle of the valve is respectively provided with an oil hole connection. High pressure fuel in the pump body is not concentrated, and the direct use of two high-pressure tubing to the high pressure common rail diesel engine fuel supply pipe, greatly simplifies the structure of the high pressure common rail pump, reduce manufacturing cost, facilitate the application of high pressure common rail fuel system in the light of automobile diesel engine.
