<p>A self cleaning liquid soap dispenser which rinses the internal parts of the soap dispenser each time soap is ejected from the nozzle. The dispenser, being adapted to be connected to a pressurized water line comprises: a liquid soap tank containing liquid soap, a piston terminating in a nozzle, a cylinder which slidingly receives the piston, and a valve means inside the cylinder, for providing selective communication between the dispenser and the pressurized water line. Whenever the piston will be pressed against the valve means, pressurized water from the water line will rush into the piston pushing the soap in the cylinder out through the nozzle. The pressurized water will rinse the valve means, the cylinder, the nozzle and the piston.</p> |
