Abstract: 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.

Abstract: A spray lustering-cleansing agent is produced by preparing a basic material substantially comprising 5.0 to 60 wt % of silicone oil obtained by emulsifying silicone oil with water in the presence of an emulsifier, 0.1 to 10.0 wt % of an emulsifier, and water and charging a spray can with the basic material in combination with a foam regulating agent and a propellant. A single spray is enough for the lustering-cleansing agent to clean a dirty tire and, at the same time, impart luster to the surface. Additional incorporation of a water-soluble organic base in the agent enables this agent to manifest an improved foaming property and consequently an improved lustering-cleansing effect.
