Abstract

본 발명은 전자제어식 동력조향장치의 압력조정밸브에관한 것으로서 특히 차량으 저속주행시 원활한 조향력을 제공하고 고속주행시 안정된 조향감을 부여하기위하여 동력 조향장치인 압력조정밸브의 로터리 밸브 측리턴부와 스플밸브의 제3 챕버부에오일통로를 형성하여 유량, 유압제어 및 안정된 방패스 압력값을 얻어 압력평형을 저압(리턴압)으로 되게 하여 압력조정밸브에서의 외부누유를 취소함과 동시에 스풀밸브의 안정된 변위를 제공하도록 하려는 것이 그 특징이다.The present invention relates to a pressure regulating valve of an electronically controlled power steering device, and in particular, to provide a smooth steering force at low speeds of a vehicle and to provide a stable steering feeling at high speeds. An oil passage is formed in the third chapter to obtain a flow rate, hydraulic control, and stable shield pressure value so that the pressure balance becomes low (return pressure) to cancel external leakage from the pressure regulating valve and at the same time stable displacement of the spool valve. Its feature is that it is intended to provide.

제1,2 포트 및 이에 연통된 제1,2 챔버를 포함하고 차량의 주행속도와 각속도에 따라 솔레노이드 밸브에 의해 스풀밸브를 연동시켜 제1,2 챔버의 압력을 조정하는 동력조향장치의 압력조정밸브에 있어서 상기 제1,2 포트의 유량 및 유압을 제어하고, 제1,2 포트를 입,출력포트로 이용하거나 제1,2 포트의 치환시 안정된 바이패스 압력값을 얻을 수 있고 스풀밸브의 제3,4 챔버에 압력평형을 저압(리턴압)으로 가능토록 로타리밸브측의 리턴부와 스풀밸브의 제3 챔버부와의 오일 통로를 형성하며, 밸브몸체(12)에는 스풀밸브(20)를 설치하여 매우 안정된 스풀밸브(20)의 변위를 유지시키는 것을 특징으로 하는 전자제어식 동력조향장치의 아력조정밸브.Pressure adjustment of the power steering device including the first and second ports and the first and second chambers connected thereto and adjust the pressure of the first and second chambers by interlocking the spool valve by the solenoid valve according to the traveling speed and the angular speed of the vehicle. In the valve, the flow rate and hydraulic pressure of the first and second ports can be controlled, and the stable bypass pressure value can be obtained when the first and second ports are used as the input and output ports or the first and second ports are replaced. In the third and fourth chambers, an oil passage is formed between the return portion of the rotary valve side and the third chamber portion of the spool valve so that the pressure balance can be performed at low pressure (return pressure), and the spool valve 20 is formed on the valve body 12. The control valve of the electronically controlled power steering, characterized in that to maintain a very stable displacement of the spool valve 20 by installing a.
