In this paper, we investigated the effects of the resistance of an oil feeding pipe on the discharge characteristics of an oil pump for a horizontal type compressor. This pump uses fluidic diodes in place of conventional valves. The discharge characteristics of this pump depend on the resistance balance between the discharge line and the suction line. The resistance of the oil pipe is as remarkable as that of fluidic diodes. This resistance is composed of not only friction and velocity head, but also the inertia of the oil in it. The effect of the resistance becomes larger as the diameter of this pipe decreases. So we analyzed the resistance of each section of this pump and calculated the change of the flow rate under various pipe diameters. As a result of this study, we have found that the optimum diameter of the pipe gives us the greatest discharge of the oil feeder pump.
