A magnetic control valve is connected to the reaction device to control fluid pressure applied thereto in accordance with a vehicle operating condition, such a vehicle speed. A flow dividing valve serves to divide the pressure fluid of a constant flow rate in a predetermined ratio into first and second flows which are respectively directed to the servo-valve and reaction device. A bypass conduit provided with a bypass orifice is connected between the fluid source and the servo-valve in parallel relation with the flow dividing valve.

The power transmission includes: a drive gear rotating in tandem with the motor shaft and forming a bevel gear with linearly extending teeth; a ball screw mechanism disposed co-axial with the rack bar and converting a rotational motion to a linear motion; and a driven gear rotating in tandem with a nut of the ball screw mechanism, meshing with and moving in tandem with the drive gear, and forming a bevel gear with linearly extending teeth. The drive gear and/or the driven gear can be adjusted so that backlash between the two elements can be adjusted in a continuous, non-stepped manner.

摘要： A power steering system which includes a fluid source that supplies pressure fluid of a constant flow rate, a fluid motor for supplementing manual steering torque, a servo-valve for distributing fluid to the fluid motor, and a reaction device for applying hydraulic reaction or feeling to a steering wheel. A magnetic pressure control valve is connected to the reaction device to control fluid pressure applied thereto in accordance with a vehicle operating condition, such a vehicle speed. A flow dividing valve serves to divide the pressure fluid of a constant flow rate in a predetermined ratio into first and second flows which are respectively directed to the servo-valve and reaction device. The predetermined ratio is varied such that the flow rate of the fluid supplied to the reaction device increases as the pressure of the fluid supplied to the fluid motor increases.

摘要： An oil pump apparatus, including a pump mechanism portion for discharging operating fluid, a valve-receiving bore formed in a housing, a flow control valve arranged in the valve-receiving bore connected to a bypass hole, and a bypass passage. The bypass passage is connected to the bypass hole, having a space radially extending from an edge of the bypass hole in a fluid stream direction of the excess operating fluid spouting from an opening area of the bypass hole. When fluid stream of the excess operating fluid reaches the inner surface of the bypass passage, the pressure of the excess operating fluid has been weaken sufficiently because fluid stream of the excess operating fluid is diffused by the long span of the bypass passage extended from the edged of the bypass hole. Therefore, the inner surface of the bypass passage is protected from cavitation damages and erosion.
