    • PURPOSE: An expansion valve is provided to suppress vibration of a valve element of an expansion valve accompanied with a change in pressure of a refrigerant. CONSTITUTION: A valve main body(5a) has an orifice(7) communicating a high-pressure side path(5b) where a refrigerant flows in, with a low-pressure side path(5c) where the refrigerant flows out. A valve element(8) controls an amount of the refrigerant flowing in the orifice. An operating rod(9b) operates the valve element in valve opening direction. A driving element drives the operating rod. A restricting element(10) is mounted at the valve main body for restricting the valve element from the side by elastic force thereof.
    • 目的:提供一种膨胀阀,用于抑制伴随制冷剂压力变化的膨胀阀的阀元件的振动。 构成:阀主体(5a)具有将制冷剂流入的高压侧通路(5b)与制冷剂流出的低压侧路径(5c)连通的孔口(7)。 阀元件(8)控制在孔中流动的制冷剂的量。 操作杆(9b)在阀打开方向上操作阀元件。 驱动元件驱动操作杆。 限制元件(10)安装在阀主体上,用于通过其弹力将阀元件从侧面限制。
