    Abstract: A tire fill valve (2) having pressure relief and tire fill fluid gas flow limiting characteristics for use in filling tires to a predetermined pressure from a large flow capacity gas source delivering fill gas at a substantially greater pressure. Gases utilized typically are air or nitrogen. The valve (2) of the invention is wheel mounted intermediate the gas pressurizing source and the tire gas valve inlet (1). Tire fill gas from a high pressure high capacity source passes through a flow limiting orifice (26) having a positive closure or shutoff member (28) and passes through a pressure sensitive chamber (42) as it enters the tire. Chamber pressure is sensed by a spring loaded valve disk (46) controlling relief or venting orifices. When fill pressure in the pressure sensitive chamber (42) exceeds a predetermined value established by the valve disk area and valve disk springs (44), the disk (46) lifts allowing the venting of the fill gas. Overpressurization of the pressure sensitive chamber (42) and tire with the disk (46) in its relief position is prevented by limited flow and/or positive flow shutoff through the chamber entrance or flow limiting orifice (26).

    Abstract translation: 一种轮胎填充阀(2),其具有压力释放和轮胎填充流体气体流动限制特性,用于将来自大流量气体源的轮胎填充到预定压力,所述大流量气体源以明显更大的压力输送填充气体。 所使用的气体通常是空气或氮气。 本发明的阀(2)是车轮安装在气体加压源和轮胎气体阀入口(1)的中间。 来自高压大容量源的轮胎填充气体通过具有正闭合或关闭构件(28)的流通孔(26),并且当其进入轮胎时通过压力敏感室(42)。 腔室压力由控制浮力或排气孔的弹簧加载的阀盘(46)感测。 当压力敏感室(42)中的填充压力超过由阀盘区域和阀盘弹簧(44)确定的预定值时,盘(46)提升以允许填充气体的排放。 通过限制流动和/或通过室入口或流通孔(26)的正流量关闭来防止压敏室(42)和具有盘(46)处于其释放位置的轮胎的过压。
