Abstract

PURPOSE: To economize the wasteful power consumed in driving the pump by instituting a simple circuit so constituted that an increasing or decreasing of oil supply amount that is appropriately effective over every rotation speed region can be automatically realized.
CONSTITUTION: As the rotation speed of driving shaft 12 gradually increases, the exhaust amount of hydraulic pump 1 also rises. At the same time the pressure difference rises owing to the throttle 3 and when the pressure difference reaches the prescribed point, namely the rotation number reaches P point, relief valve 6 is opened and exhaust oil of hydralic pump 2 is relived. Then, as to the oil amount thrown into first load 9, summation of exhaust oil amounts of both pumps 1 and 2 thus far added will be the exhaust amount of pump 1 only and only this exhaust oil of pump 1 performs the work of the first load 9, after which it confluxes once again with the exhaust oil of pump 2 and these confluent exhaused oils perform the work of the second load 10, after which they circulate back to thump-tank 11.
