Abstract

PURPOSE: To improve accuracy of measurements under power absorption even when the output speed of the speed change and steering equipment to be tested are low, by installing hydraulic oil change-over valves.
CONSTITUTION: In the test to absorb power of the speed change and steering equipment to be tested, hydraulic oil pumps 5, 5' operate, hydraulic change-over valves 9, 9' are shifted from positionIto position II, and the oil passages d, d' are connected with e, e' and the pressure oil passes through passages d, d' from pumps 5, 5', hydraulic change-over valves 9, 9' and ducts e, e' and is fed to the ducts c, c' to the discharge side of the hydraulic oil pumps. Therefore, even when output speed of the speed change and steering equipment 1, namely the output speed of the oil pump are low and the oil pressure at the discharge side is low, much of the pressure oil added with pressure oil from the oil pump 5, 5' is flown to the relief valves 4, 4', and the pressure setting of the relief valves 4, 4' can be performed accurately.
