Abstract
PURPOSE: To reduce power consumption of an engine greatly by performing the control of excessive flow which is caused by the increase of discharge from a pressure fluid supplying pump in proportion to its revolutions, using a means working in compliance with the car speed or the number of revolutions of engine.
CONSTITUTION: Main pump P to supply the pressure fluid to the power assist mechanism 4 and a subpump Ps having an increasing discharge with the number of revolutions of the engine are installed in such an arrangement as driven by the engine 1. A passage 8 in communication to a recerver tank 3 is provided in the discharge pipe 6 of the pump P, and on the way of this passage 8a control valve 9 is installed to control its rate of flow. This valve 9 is so arranged as to open the passage 8 according to the discharge pressure of the subpump Ps. A safety circuit 17 in communication separately to the reserver tank diverges from the discharge pipe 6, and on the way of this circuit 17 a relief valve 18 is installed to allow the pressure oil to flow aside when the liquid pressure in the assist 4 becomes excessive.
