    • A vehicle tire inflation system includes an air supply source in fluid communication with multiple tires of the vehicle. A pneumatic conduit extends between and is in fluid communication with the air supply source and the tires. Means are fluidly connected to the pneumatic conduit for enabling selective inflation and deflation of the tires. The means include a first pneumatic circuit for inflation of the tires, and a second pneumatic circuit for deflation of the tires. The second pneumatic circuit is discrete from the first pneumatic circuit and is common to more than one of the tires. The means provides controlled deflation of the tires in the second pneumatic circuit based upon a predetermined condition, preventing deflation of the tires until the vehicle is parked, or limiting the deflation of the tires, which in turn enables the tire inflation system to accommodate a desirable increased pressure in the tires.
    • 车辆轮胎充气系统包括与车辆的多个轮胎流体连通的供气源。 气动导管在空气供应源和轮胎之间延伸并且与空气供应源和轮胎流体连通。 装置流体地连接到气动导管,用于使轮胎有选择性的充气和放气。 该装置包括用于轮胎充气的第一气动回路和用于轮胎放气的第二气动回路。 第二气动回路与第一气动回路分离,并且对于多于一个的轮胎是常见的。 该装置基于预定条件提供第二气动回路中的轮胎的受控放气,防止轮胎放气直到车辆停放,或限制轮胎的通风,这又使得轮胎充气系统能够适应期望的 增加轮胎的压力。

    • A constant pressure vehicle tire inflation system includes an air supply source. A first wheel valve is in fluid communication with a first tire of the vehicle, and a second wheel valve is in fluid communication with a second tire of the vehicle. A pneumatic conduit extends between and is in fluid communication with the air supply source and the wheel valves. At least a portion of the pneumatic conduit remains charged with air from at least one of the supply source and the tires. The system includes means for distributing air flow between the pneumatic conduit and the first and second wheel valves, in which the wheel valves and the means selectively maintain fluid communication between the first and second tires and the pneumatic conduit to provide pneumatic balancing between the tires, and the wheel valves provide emergency protection when a tire experiences significant pressure loss.
    • 恒压车辆轮胎充气系统包括供气源。 第一轮阀与车辆的第一轮胎流体连通,并且第二轮阀与车辆的第二轮胎流体连通。 气动导管在空气供应源和车轮阀之间延伸并与之流体连通。 气动导管的至少一部分保持从供应源和轮胎中的至少一个充满空气。 该系统包括用于在气动管道和第一和第二轮阀之间分配空气流的装置,其中车轮阀和装置选择性地保持第一和第二轮胎与气动管道之间的流体连通,以在轮胎之间提供气动平衡, 当轮胎经历显着的压力损失时,轮毂阀门提供紧急保护。

    • A vehicle tire inflation system (100) includes an air supply (52) that is connected to a vehicle tire by a pneumatic conduit (56). A pump (101, 102) that is independent of and pneumatically parallel to the vehicle air supply (52) includes an inlet and an outlet (104). The pump (101, 102) inlet receives air from atmosphere, the pump (101, 102) compresses the air, and the pump outlet (104) is fluidly connected to the pneumatic conduit (56). When the air pressure in the pneumatic conduit (56) drops below a predetermined level, compressed air from the pump (101, 102) is introduced into the pneumatic conduit (56), thus increasing the air pressure in the conduit (56) to increase the air pressure that is available to the tire. A reservoir tank (154), which is also independent of the vehicle air supply (52), may be in fluid communication with the pump outlet (104) and the pneumatic conduit (56).
    • 车辆轮胎充气系统(100)包括通过气动导管(56)连接到车辆轮胎的空气供应(52)。 独立于气动平行于车辆空气供应(52)的泵(101,102)包括入口和出口(104)。 泵(101,102)入口从大气接收空气,泵(101,102)压缩空气,泵出口(104)流体地连接到气动导管(56)。 当气动管道(56)中的空气压力下降到预定水平以下时,来自泵(101,102)的压缩空气被引入到气动导管(56)中,从而增加导管(56)中的空气压力以增加 可用于轮胎的空气压力。 也独立于车辆空气供应(52)的储存罐(154)可以与泵出口(104)和气动管道(56)流体连通。
