摘要： A fluid flow control valve has a resilient diaphragm that engages a valve seat. A line contact is formed between the diaphragm and the valve seat at or closely adjacent the outer diameter of the valve seat. This enhances the ability of the valve to seal under low fluid pressures. The diaphragm is reinforced by a plastic reinforcing member which is formed separately from the diaphragm. The reinforcing member and the diaphragm are inserted together in a press fit, and barbed posts on the reinforcing member hold the two together.

摘要： An improved valve includes an inlet, an outlet and a valve seat. A flexible diaphragm assembly seals against the valve seat. A bleed assembly extends into a pressure chamber located above the diaphragm for bleeding fluid pressure out of the chamber, thereby opening the valve. The bleed assembly includes a hollow tube inserted into a plastic plunger seat that is carried on the cap of the valve beneath the plunger of an actuating solenoid. Such a bleed assembly does not need a bleed tube having a precisely controlled length, and is not sensitive to flexure of the cap.

摘要： A fluid flow control valve has a diaphragm for sealing against a valve seat. The diaphragm includes a bleed hole for passing fluid from one side of the diaphragm to the other. A debris arrestor comprising a one-piece flexible tag is inserted into the bleed hole by deforming the tag to pass therethrough. The tag after insertion expands to retain itself in the bleed hole.

摘要： An improved sprinkler (2) includes a body (4) which includes a pop-up nozzle (10). Nozzle (10) is sufficiently smaller than body (4) to create a gap therebetween as nozzle (10) rises out of body (4). An annular guard (30) separate from nozzle (10) is located in the upper end of body (4) and is normally urged out of body (4) by a spring (34). Guard (30) is normally engaged by a cover (18) on nozzle (10) so that nozzle (10) normally keeps guard (30) retracted within body (4). However, as nozzle (10) rises from body (4), guard (30) will be projected upwardly substantially as soon as nozzle (10) rises to immediately seal the gap. Stops (40) and (42) are provided on guard (30) and body (4) for limiting the upward movement of guard (30) to an amount less than the upward movement of nozzle ( 10).
摘要翻译： 改进的喷洒器（2）包括包括弹出喷嘴（10）的主体（4）。 当喷嘴（10）从体（4）上升时，喷嘴（10）足够小于主体（4）以在其间产生间隙。 与喷嘴（10）分离的环形防护罩（30）位于主体（4）的上端，并且通常由弹簧（34）推出主体（4）。 护罩（30）通常由喷嘴（10）上的盖（18）接合，使得喷嘴（10）通常保持保护件（30）缩回到主体（4）内。 然而，当喷嘴（10）从主体（4）上升时，一旦喷嘴（10）上升，保护罩（30）将基本上向上突出，以立即密封间隙。 止动件（40）和（42）设置在防护件（30）和主体（4）上，用于将防护件（30）的向上运动限制到小于喷嘴（10）向上运动的量。
