The present invention relates to an integrated electronic expansion and direction switch valve. More specifically, the present invention aims to provide an expansion valve which is able to switch status into closed status for blocking a flow of refrigerant and into expansion status for expanding the refrigerant by forming an expansion interval or into completely opened status for distributing the refrigerant without expanding the refrigerant. The integrated electronic valve for expansion and direction switch comprises: a valve body (100) made in a block shape to have a flow path (110) inside to make an input port (101) communicate with an output port (102); a rotary valve (200) placed in the flow path (110) to be rotatable in a circumferential direction and to have an expansion recess (210) and a flow path hole (220); a valve plate (300) which has a penetrating hole (310); an airtight member (400) placed on one or more surfaces of the rotary valve (200) to be rotatable as one body toward the valve plate (300) by being made of elastic airtight materials, thereby securing airtightness between the penetrating hole (310) of the valve plate (300) and the rotary valve (200); and a driving member (500) which transfers rotary force to the rotary valve (200). The present invention simplifies the configuration of an air conditioner for a vehicle to enable precise control, and especially, increases the airtightness against the refrigerant and the processability and productivity for the products to reduce the production unit cost of the products, thereby maximizing market competitiveness.

    본 발명은 전자식 팽창 및 방향전환 일체화 밸브에 관한 것으로서, 특히, 냉매의 흐름을 차단하는 폐쇄 상태는 물론, 팽창 간극을 형성하여 냉매를 팽창시키는 팽창 상태나 냉매를 팽창시키지 않고 그대로 유통시키는 완전 개방 상태로도 절환하는 것이 가능한 팽창밸브를 제공하기 위한 것으로서, 블록 형상으로 이루어져 입력 포트(101)와 출력 포트(102)를 연통시키는 유로(110)가 내부에 형성된 밸브바디(100)와; 유로(110) 내에서 원주방향으로 회전 가능하게 마련되되, 팽창 리세스(210)와 유로구멍(220)이 형성되는 회전 밸브(200)와; 관통공(310)이 형성되는 밸브 플레이트(300)와; 탄성 기밀재질로 이루어져 밸브 플레이트(300)를 향하여 회전 밸브(200)의 적어도 일면에 일체로 회전 가능하게 마련되어, 밸브 플레이트(300)의 관통공(310)과 회전 밸브(200)의 상호간에 기밀성을 확보하는 기밀부재(400)와; 회전 밸브(200)에 회전력을 전달하는 구동부재(500)를 포함하여, 차량용 공조기의 구성을 단순화 하면서 정밀 제어를 가능하게 하고, 특히 냉매에 대한 기밀성 및 제품에 대한 가공성 및 생산성을 높여 제품의 생산단가를 낮추는 한편 시장 경쟁력을 극대화 시킬 수 있도록 하는 것이다.
