摘要： A thermal actuator of the expansible wax type is disclosed having an actuator rod extending through an enlarged clearance hole in an upper guide casing, a closely fitting hole in a guide washer, and a snugly fitting anti-chafe ring. The washer and ring are located intermediate the upper surface of a flexible diaphragm and a counterbore defined by the guide casing. The clearance between the outer diameter of the guide washer and the counterbore formed by the guide casing is substantially less than the clearance between the guide casing opening and the actuator rod. The guide washer and anti-chafe ring mounting arrangement in relation to the guide casing opening provides improved rod alignment and a self-cleaning action as the rod moves.

摘要翻译： 公开了一种可膨胀蜡类型的热致动器，其具有延伸穿过上导向壳体中的扩大的间隙孔的致动器杆，导向垫圈中的紧密配合的孔以及紧密配合的防冻环。 垫圈和环位于柔性隔膜的上表面和由导向壳限定的沉孔之间。 导向垫圈的外径和由导向壳体形成的沉孔之间的间隙大致小于引导壳体开口和致动器杆之间的间隙。 相对于导向壳体开口的导向垫圈和防冻环安装装置提供了改进的杆对准和杆移动时的自清洁作用。

摘要： A valve assembly of the type providing bypass flow through a branch channel when the movable valve member is in the closed position to block flow through the main flow channel outlet. A venturi device is disposed in the main channel upstream of the movable valve member, and the venturi has secondary ports provided through the wall at the throat section. When the movable valve member is in the closed position, flow into the venturi exits at the flow ports and flows through the bypass channel. When the movable valve member is in the open position, flow discharges from the venturi, through the main channel outlet port downstream of the movable valve member, thereby causing reduced pressure at the venturi throat and preventing flow through the secondary ports to the bypass channel.
