    • A cartridge type regulator and shut-off valve assembly for a water cooler includes a hollow cylindrical body received in a mating bore in a casting which is part of the cooler. The cartridge includes a hollow cylindrical body which, at its inner end, is formed with an inlet passage and an outlet passage connected to each other by a valve-controlled opening in the inlet passage. This opening faces axially inwardly of the body while the valve faces outwardly and is carried by an axially movable stem. A manual actuator is depressed to slide the valve stem inwardly and move the valve away from the opening and the valve is returned by a spring to the closing position when the actuator is released. The valve-controlled opening, as well as a part of the inlet passage, is formed in a bar which extends diametrically across the inside of the body and is an integral part of the latter so that the opening does not shift or creep even if the parts are made of molded plastic. Assembly of the valve stem is facilitated by forming it in parts with the inner part being U-shaped. The valve is carried on the crosspiece of the U and the legs of the U straddle the bar and are formed with hooks which snap into engagement with hooks on another part of the stem so that the parts form a unitary stem.
    • 用于水冷却器的盒式调节器和截止阀组件包括容纳在作为冷却器的一部分的铸件中的配合孔中的中空圆柱体。 筒体包括中空圆柱体,其在其内端处形成有通过入口通道中的阀控制开口彼此连接的入口通道和出口通道。 该开口面向主体的轴向内侧,而阀面向外并由轴向可移动的杆承载。 手动致动器被压下以将阀杆向内滑动并将阀移离开口,并且当致动器被释放时,阀由弹簧返回到关闭位置。 阀门控制的开口以及入口通道的一部分形成在直径沿主体内侧延伸的杆中,并且是后者的整体部分,使得开口不移动或蠕动,即使 零件由模压塑料制成。 通过将内部部件为U形的部件形成,便于阀杆的组装。 阀被承载在U的横档上,并且U的腿部跨越杆,并且形成有钩,其钩与钩在杆的另一部分上的接合,使得部件形成单个杆。
