Abstract
Abstract A high pressure pump, such as a gear pump or small piston pump, is connected by means of a clutch to be driven by the engine; a collapsible water bag, of thermoplastic material and capable of holding in the order of 8 to 10 gallons of water, is located in the car, for example in the trunk space; a thin flexible tubing is spooled on a reel, located in the car (for example under the hood), and hydraulic interconnections are provided to take water from the water bag through the pump and to the tubing, so that a self-contained car washing system is provided capable of applying a water stream under pressure. When not in use, the plastic water bag is collapsed, and can fold flat against the inner wall of the trunk.
