流路切换阀
摘要：
本发明提供一种能够延长旋转件的寿命的旋转式的流路切换阀。本发明的流路切换阀包括固定件(1)和能相对于该固定件(1)滑动并旋转的旋转件(2)，上述固定件(1)具有在旋转件(2)旋转滑动的滑动面开口的多个孔(3)，上述旋转件(2)具有用于将上述多个孔(3)中的两个以上的孔(3)连结起来的流路槽(4)，其中，在上述流路槽(4)的边缘，上述旋转件(2)以大于120°的接触角(α)接触于该旋转件(2)与上述固定件(1)之间的滑动面(6)。
摘要（英）：

Provided is a rotary-type flow path switching valve having a rotor with an extended lifetime. The flow path switching valve is provided with a stator (1) and a rotor (2) which rotates while sliding relative to the stator (1). The stator (1) has ports (3) open at the sliding surface on which the rotor (2) slides in a rotating manner. The rotor (2) has a flow path groove (4) for connecting two or more of the ports (3). At the edges of the flow path groove (4), the rotor (2) is in contact with the sliding surface (6) between the rotor (2) and the stator (1) at a contact angle (alpha) greater than 120 DEG.
