Abstract
PURPOSE: To improve engine fuel consumption efficiency by using a variable capacity pump for power steering system and always supplying only the necessary flow for the system regardless of the rotational speed of the pump.
CONSTITUTION: When a steering wheel is maintained at an optional angle, the hydraulic pressure supplied to oil passage 7, orifice 16, oil passge 8, 4-way selector valve 60, oil passage 12, oil chamber 19, duct 23 and oil chamber 20 causes no exhaut oil flow except the one discharged due to leakage of the sysem. Accordingly, there is little difference in hydraulic pressure between the force and the back of the orifice 16 and further the hydraulic pressure in each oil chamber 53, 54, 55 of a flow control valve 50 is almost the same, and a spool 52 is set to the right hand in the figure, due to the action of a spring 51. Then, pressurized oil in the oil passage 7 is supplied to an oil chamber 40 of a variable capacity vane pump 30 through an oil passage 70. a slide casing 33 is then moved to the right, resulting in reduction in a degree of eccentricity and quantity of discharge.
