摘要： A fluid filtering stop valve having a body with a cylindrical chamber having a circumferential sidewall with inlet, outlet and flush ports, and a cylindrical plug member rotatably disposed in the chamber. The plug member has spaced apart first and second circular plates with an off-center filtering screen extending therebetween. The plug member is rotatably between a filtering position in which the screen is located in the fluid flow between the inlet and outlet ports, a backflushing position in which the screen is located in the fluid flow between the inlet and flush ports, with the filtering side of the screen toward the flush port, and a closed position in which an arcuate plate washer loosely retained between the first and second plates is positioned to seal the flush and outlet ports. In the filtering position the washer seals only the flush port and in the flush position the washer seals only the outlet port. The screen uses outwardly diverging ribs to reduce lodging of material between the ribs. A second screen filters the fluid from the inlet port during backflushing.

摘要： A snap-on, easily removable, fluid shut off valve (with pipe and interlocking member) that is useful as a low cost, primary turn off valve for domestic and commercial fluid fixtures and is quickly installed by manual snap-on between the inlet fluid supply and the supply pipe to conventional fixtures such as faucets or the like. The valve comprises a rigid housing having an inlet chamber and an outlet chamber, and a cross-over passage separating the first and second chambers that houses a moveable ball or poppet valve member that is held in the cross-over chamber by a spring retainer. A mechanical plunger or cam device (operable from the exterior of the housing) is disposed within the outlet chamber for contacting and pushing the ball or poppet valve member against the spring retainer, away from the valve seat, to open the valve. The first and second chamber openings receive spiral-shaped spring pipe end retaining members, each having an inside diameter smaller than the outside diameter of the inserted pipe mounted between level bushings. Each spiral-shaped retaining member has radial segments that deform in the direction of the pipe inserted that interlocks the pipe end in each chamber. Cooperating fluid seals prevent leakage.
摘要翻译：可用作家用和商业流体固定装置的低成本主要关闭阀的快速可拆卸的流体截止阀（带有管道和互锁构件），并且通过手动卡扣在入口流体之间快速安装供应和供应到常规固定装置如龙头等。阀包括具有入口室和出口室的刚性壳体，以及分隔第一和第二腔室的横穿通道，其容纳通过弹簧保持器保持在交叉室中的可移动球体或提升阀构件。机械柱塞或凸轮装置（可从壳体的外部操作）设置在出口室内，用于接触并推动球或提升阀构件抵靠弹簧保持器远离阀座以打开阀。第一和第二腔室开口接收螺旋形的弹簧管端部保持构件，每个具有小于安装在层间衬套之间的插入管的外径的内径。每个螺旋形保持构件具有沿插入的管的方向变形的径向段，其互锁每个室中的管端。合作流体密封件防止泄漏。
