摘要: In order to accommodate expansion and contraction in a fuel system, even in the presence of extremes of temperature, while maintaining the fuel system pressure at ambient, a thermal expansion reservoir is provided. The thermal expansion reservoir includes a rigid housing having releasably interconnected first and second housing portions provided with a fluid inlet port and a vent. A resilient bladder is disposed within the housing between the inlet port and the vent in a manner dividing the housing into a fluid expansion chamber and a pressure relief chamber, each of variable size depending upon the fluid pressure in the fluid expansion chamber. A redundant seal arrangement is integrally associated with the resilient bladder to form primary and secondary seals between the housing portions while joining the resilient bladder to the housing. The thermal expansion reservoir is also formed such that the resilient bladder has a first wall portion leading from the housing in the direction of the vent to a return bend and a second wall portion leading from the return bend in the direction of the inlet port to an end cap. With this construction, the return bend initiates rolling of the second wall portion toward the vent and the second wall portion is tapered to promote rolling of the second wall portion toward the vent in an automatically controlled and substantially frictionless fashion.

摘要: A gas flow rate measurement apparatus for obtaining a normalized flow rate of a gas having at least one liquid component. The gas travels from an upstream position and in a downstream direction. The gas flow rate measurement apparatus comprises a gas inlet conduit in the upstream position for receiving the gas; a gas flow conditioning section in fluid communication with the gas inlet conduit and in a first downstream position for conditioning the gas to vaporize substantially all of the at least one liquid component without adding any other gas; a flow rate measurement section in fluid communication with the gas flow conditioning section and in a second downstream position more distant from the upstream position than the first downstream position, the flow rate measurement section including at least one sensor for sensing at least one state variable for the gas and generating at least one gas state signal, and a flow rate sensor for measuring an actual flow rate of the gas and generating a flow rate signal, and a processing device operatively coupled to the flow rate measurement section for using the at least one gas state signal and the flow rate signal to obtain the normalized mass flow rate. A related method also is provided.
