    摘要: A washing liquid jet device for an automobile window glass is disclosed, which comprises a first pumping unit for pumping a liquid in a first vessel, a second pumping unit for pumping a liquid in a second vessel, and a joining chamber having a first flow path and a second flow path. A unidirectional valve is provided at each of the joining chamber inlets of the flow paths such that it permits flow of liquid into the chamber but blocks the flow of liquid out of the chamber. A discharge side flow path of the first pumping unit is connected to the first flow path of the joining chamber, the discharge side flow path of the second pumping unit is connected to the second flow path of the joining chamber, and the outlet of the joining chamber is connected to one end of a feed-out duct, the other end of which is connected to a jet nozzle.
