Abstract: A heat pump system for a vehicle having a complex valve device including a three-way valve, an on-off valve, expansion means and connection blocks are formed integrally with one another, the three-way valve part being connected to the refrigerant circulation line of an inlet of the exterior heat exchanger such that the refrigerant selectively bypasses the exterior heat exchanger, the on-off valve part being connected to an inlet of the bypass line to open and close the bypass line. Connection blocks connect the three-way valve part and the on-off valve part with the refrigerant circulation line of an outlet of the exterior heat exchanger to communicate with each other. Expansion means are connected to an inlet of the three-way valve part to selectively expand refrigerant discharged from an interior heat exchanger. All functions of the heat pump system are thus conducted through a refrigerant control of the complex valve device.

Abstract translation: 具有包括三通阀，开闭阀，膨胀装置和连接块的复合阀装置的车辆用热泵系统彼此一体地形成，三通阀部分连接到制冷剂循环管线 的外部热交换器的入口，使得制冷剂选择性地绕过外部热交换器，开关阀部分连接到旁路管线的入口以打开和关闭旁路管线。 连接块将三通阀部件和开关阀部件与外部热交换器的出口的制冷剂循环管线相互连通。 膨胀装置连接到三通阀部件的入口，以选择性地膨胀从内部热交换器排出的制冷剂。 因此，热泵系统的所有功能通过复合阀装置的制冷剂控制来进行。
