The invention discloses a personal service unit (PSU), and the PSU includes a housing, a dial, and a flow control ring. The dial is rotatable about the housing. The housing includes a longitudinal axis therethrough and a first end and a second end opposite the first end. The dial includes a helical first portion along an interior wall of the dial. The flow control ring includes a helical second portion along an exterior wall of the flow control ring. The helical second portion rotatably mates with the helical first portion and rotation of the dial in a first direction moves the flow control ring in a first direction along the longitudinal axis to cause a first adjustment in airflow past the flow control ring and rotation of the flow control ring in an opposite direction moves the flow control ring in an opposite direction to cause a second adjustment in airflow past the flow control ring.

    通用乘客服务单元。一种个人服务单元(PSU)包括外罩、拨盘和流量控制环。拨盘可围绕外罩旋转。外罩包括穿过所述外罩的纵向轴线,以及第一端和与第一端相反的第二端。拨盘包括沿拨盘的内壁的螺旋形第一部分。流量控制环包括沿流量控制环的外壁的螺旋形第二部分。螺旋形第二部分与螺旋形第一部分可旋转地配合,并且拨盘在第一方向上的旋转在沿纵向轴线的第一方向上移动流量控制环,以引起经过流量控制环的气流的第一调节,并且流量控制环在相反方向上的旋转在相反方向上移动流量控制环,以引起经过流量控制环的气流的第二调节。
