Unitary poppet valve assembly for a proportioning valve
摘要：
The unitary poppet valve assembly (50) comprises an annular retainer (52) having an open end (54) and an opposite end (55) with a small diameter opening (56) therein. The annular retainer (52) has a plurality of fingers (58) extending laterally therefrom for engagement with the body (12) of a proportioning valve assembly (10). A poppet (70) comprises a poppet head (72) extending radially outwardly from a longitudinal shaft (74), and an oppositely disposed abutment (76). The shaft (74) extends slidably through the small diameter opening (56) in the annual retainer (52), the abutment (76) engaging the retainer (52) adjacent the opening (56). A spring (60) is disposed between a corner or shoulder (57) of the annular retainer (52) and a shoulder (77) defined between the poppet head (72) and poppet shaft (74). The poppet (70) includes a central through opening (78) extending through the abutment (76) and to the head (72), wherein the opening (78) communicates with a lateral through opening (80) of the shaft (74). The unitary poppet valve assembly (50) may be inserted directly within an inlet opening (13) of the proportioning valve assembly (10) so that the fingers (58) engage the body (12) of the proportioning valve assembly (10).
摘要（中）：

整体式提升阀组件（50）包括具有开口端（54）和在其中具有小直径开口（56）的相对端（55）的环形保持器（52）。 环形保持器（52）具有从其横向延伸的多个指状物（58），用于与配比阀组件（10）的主体（12）接合。 提升阀（70）包括从纵向轴（74）径向向外延伸的提升头（72）和相对设置的支座（76）。 轴（74）可滑动地延伸穿过年度保持器（52）中的小直径开口（56），邻接件（76）与邻近开口（56）的保持器（52）接合。 弹簧（60）设置在环形保持器（52）的角部或肩部（57）和限定在提升头（72）和提升轴（74）之间的肩部（77）之间。 提升头（70）包括延伸通过邻接部（76）和头部（72）的中心通孔（78），其中开口（78）与轴（74）的横向通过开口（80）连通。 整体式提升阀组件（50）可以直接插入在配比阀组件（10）的入口（13）内，使得指状物（58）接合配比阀组件（10）的主体（12）。
