    • A multi-mode pressure relief valve (12) includes a body (28) having fluid inlet (30) and outlet (32) ports and a compressed gas inlet port (34). The fluid ports and gas port isolated from one another. A reciprocating piston (58) is in communication with the gas port. A valve stem (44) is movable between an open condition and a closed position to permit and stop flow communication between the fluid ports. A spring is disposed between the valve stem and the piston and urges the piston and valve stem away from one another. The valve is operable in at least three modes, an operating mode in which the valve is open, the stem is spaced from the piston, and the piston applies pressure on the stem, and in which the pressure is balanced by fluid pressure the inlet, a zero- state mode in which the valve is open, the stem is spaced from the piston, the spring (50) is in a relaxed state, and the piston applies no pressure on the valve stem, and a relief mode in which the valve is open, the stem contacts or is in close proximity to the piston and the spring is in a compressed state due to the fluid pressure.
    • 多模式减压阀(12)包括具有流体入口(30)和出口(32)端口的主体(28)和压缩气体入口(34)。 流体端口和气体端口彼此隔离。 往复活塞(58)与气体端口连通。 阀杆(44)可在打开状态和关闭位置之间移动,以允许和停止流体端口之间的流动连通。 弹簧设置在阀杆和活塞之间并且促使活塞和阀杆彼此远离。 阀门可操作至少三种模式,阀门打开的操作模式,阀杆与活塞间隔开,活塞在阀杆上施加压力,其中压力通过流体压力平衡入口, 阀门打开的零状态模式,杆与活塞间隔开,弹簧(50)处于松弛状态,活塞对阀杆施加无压力,并且其中阀门 是打开的,杆接触活塞,并且由于流体压力弹簧处于压缩状态。

    • A double check valve reduced pressure backflow preventor assembly is configured to have a relatively small length, volume and/or weight. The assembly defines parallel, preferably coaxial, inlet (112) and outlet (128) directions. In one aspect, axis (312) of first and the axis (314) of second check valves are at an angle, preferably of 90 degrees, to the in-line axis (110). In one aspect, a relief valve (134) is positioned spaced from the in-line axis (110). First (718a) and second stop valves (718b) are enclosed in the same integral, unitary housing (142) which encloses the check valves and, preferably, some or all of the relief valve (134). The shutoff valves (718a, 718b) are preferably positioned along the in-line axis (110).
    • 双止回阀减压回流防止器组件被配置为具有相对较小的长度,体积和/或重量。 组件限定平行的,优选地同轴的入口(112)和出口(128)方向。 在一个方面,第一止回阀的第一和轴线(314)的轴线(312)与直列轴线(110)成一角度,优选为90度。 在一个方面,安全阀(134)定位成与所述直线轴线(110)间隔开。 第一(718a)和第二截止阀(718b)被封闭在相同的整体式整体式壳体(142)中,该壳体包围止回阀,优选地包括一些或全部安全阀(134)。 截止阀(718a,718b)优选地沿着直线轴线(110)定位。

    • A valve assembly for a tire inflation system with a housing that has an air supply conduit for fluidly connecting the valve assembly to the tire inflation system. The housing has disposed within a core member is rotatable under the effect of injection of pressurized air via the air supply conduit and a torsion member connected to the core member to resist rotation of the core member in a predetermined direction. Under the effect of the injection of the pressurized air at a first pressure, the core member is rotatable from a rest position to a first position and, under the effect of the injection of the pressurized air at a second pressure which is greater than the first pressure, the core member is rotatable to a second position
    • 用于轮胎充气系统的阀组件,其具有壳体,该壳体具有用于将阀组件流体连接到轮胎充气系统的空气供应管道。 布置在芯构件内的壳体可在通过空气供应导管喷射加压空气的作用下旋转,并且扭转构件连接至芯构件以阻止芯构件在预定方向上的旋转。 在以第一压力喷射加压空气的作用下,芯构件可从静止位置旋转到第一位置,并且在压缩空气以大于第一压力的第二压力的作用下 压力,芯部件可旋转到第二位置
