阅读说明：本技术 旋转伺服阀 (Rotary servo valve ) 是由 A·柯林斯 M·麦克唐纳 于 2020-02-05 设计创作，主要内容包括：一种旋转伺服阀,包括限定圆柱形空腔(107)和第一层端口的壳体部分(105)。该旋转伺服阀还包括两个相对的锯齿状侧面和相对于所述锯齿状侧面具有增大的半径的两个相对侧面,增大半径的每个侧面在两个锯齿状侧面之间延伸。阀芯部分(103)安装成相对于圆柱形空腔(107)从中间位置旋转到打开位置,其中在中间位置防止流体流过阀,而在打开位置提供流体流动路径。(A rotary servo valve includes a housing portion (105) defining a cylindrical cavity (107) and a first layer of ports. The rotary servo valve further comprises two opposite serrated sides and two opposite sides having an increased radius relative to the serrated sides, each side of increased radius extending between two serrated sides. The valve core portion (103) is mounted for rotation relative to the cylindrical cavity (107) from an intermediate position in which fluid flow through the valve is prevented to an open position in which a fluid flow path is provided.)
