Abstract: The present invention relates to a cartridge valve type electronic variable displacement pump which controls a flow rate of oil in a power steering line of a vehicle according to the speed and the steering angle of a vehicle to transmit the oil to a steering gear box. The present invention provides a new type of an electronic variable displacement pump which controls a discharge flow rate by controlling an oil compression amount in a chamber between vanes using a valve and a flow passage installed on a cartridge, thereby eliminating components such as a variable cam ring, simplifying the flow passage and the structure, and reducing the weight and material costs.

Abstract: PURPOSE: A power steering apparatus equipped with a vibration isolation device is provided to improve the steering efficiency and to prevent the generation of shimmy and kick back in a steering wheel due to the transmission of an external impact or vibration. CONSTITUTION: A power steering apparatus equipped with a vibration isolation device is composed of a cylinder(3), a control valve(4), and a rotation restrict assembly(10). The cylinder comprises a rack bar(7). The rack bar moves straight to steer a vehicle wheel. A torsion bar(5) is formed within the control valve. The torsion bar opens/closes a passage in steering the wheel. The control valve applies steering force by applying the oil pressure to the rack bar in steering the wheel. The control valve circulates the oil between the oil pump and the cylinder. The rotation restrict assembly rotates a pinion and generates the torsion of the torsion bar by bypassing the oil toward the piston valve and forming high pressure.
