Connector element

摘要

A connector element for connecting a pump assembly for use in a selective catalytic reduction system to a reagent supply of reagent fluid, the connector element comprising: a reagent flow passage arranged to receive reagent fluid at a first end from the reagent supply and to supply the reagent fluid via a second end to a reagent inlet port for reagent fluid on the pump assembly; a coolant passage for cooling fluid, the coolant passage arranged to be in communication with a coolant port on the pump assembly.

1. A selective catalytic reduction system of a vehicle comprising:
a pump assembly comprising:
a reagent inlet port which introduces reagent fluid into the pump assembly;a nozzle which provides an exit from the pump assembly for reagent to be discharged from the pump assembly such that the pump assembly pumps reagent fluid from the reagent inlet port to the nozzle; anda coolant port which introduces cooling fluid into the pump assembly or which discharges cooling fluid from the pump assembly such that the cooling fluid provides cooling to the pump assembly; and a connector element which mates with the pump assembly, the connector element defining a parting line with the pump assembly about which the connector element and the pump assembly are separable from each other, the connector element comprising:
a reagent flow passage which receives reagent fluid at a first end from a reagent supply and supplies reagent fluid via a second end to the reagent inlet port on the pump assembly; anda coolant passage which communicates cooling fluid through the connector element, the coolant passage being in communication with the coolant port on the pump assembly.
