본 발명의 일실시예에 따른 바이패스 팽창 밸브 조립체는 본체(121a, 121b)에 형성되어 유체가 유입되는 유입구(125a); 본체 내에서 유체의 유동 경로에 형성된 시트부(121c)와의 접촉에 의해 유입된 유체의 유동을 개폐하도록 제어하는 플레이트부(122a); 상기 플레이트부(122a)가 개방시에 유체가 유출되는 바이패스 유출구(125c); 상기 본체에 형성되며, 상기 플레이트부(122a)의 상류에 형성되어, 축소된 단면부를 가진 오리피스(126);를 구비한다.

    PURPOSE: A bypass expansion valve assembly and a vehicle heat pump system are provided to change a fluid flowing direction by utilizing a one-way valve without using a three-way valve so that a pressure loss is small. CONSTITUTION: A bypass expansion valve includes an inlet (125a), a plate unit (122a), a bypass outlet (125c), and an orifice (126). The inlet is formed on bodies (121a, 121b), and a fluid is supplied via the inlet. When the plate unit is in contact with a sheet unit (121a) formed on a flowing passage of the fluid inside the body, a flow of the fluid is blocked. The fluid is discharged via the bypass outlet when the plate unit is spaced from the sheet unit. The orifice is formed on the body in the upstream of the plate unit and includes a reduced cross section portion.
