Abstract: A pressure and temperature compensated valve assembly includes a flow valve allowing inflation flow from a control port to a tire port and controlling deflation flow from the tire port to the control port. A throttle valve restricts deflation flow between the tire port and the control port when deflating the tire at high flow rates or when tire pressure is high, thus enabling the flow valve to be closed. The throttle valve includes a throttle diaphragm that throttles in response to flow from the tire port and which does not restrict inflation flow from the control port. The valve assembly further includes a temperature responsive member engaging the flow valve, and which deforms in response to a change in temperature in the valve assembly, thus negating temperature effects on the flow valve, allowing the flow valve to close at a consistent force across a range of operating temperatures.

Abstract translation: 压力和温度补偿阀组件包括允许从控制端口到轮胎端口的充气流量并且控制从轮胎端口到控制端口的通气流的流量阀。 当在高流量下或当轮胎压力高时使轮胎排气时，节流阀限制轮胎端口和控制口之间的通气流，从而使流量阀能够关闭。 节流阀包括节流阀，其响应于来自轮胎端口的流动而节流，并且不限制来自控制端口的充气流。 阀门组件还包括接合流量阀的温度响应构件，并且响应于阀组件中的温度变化而变形，从而抵消对流量阀的温度影响，允许流量阀以一致的力 工作温度范围
