    • A double diaphragm leakproof sealing device for electric windscreen washer pumps has a directing chamber housing two very resilient diaphragms which may be provided with compensating elements for loss of resilience. When there is no leaning liquid pressure, the two diaphragms permanently block, by way of their own resilient action and, as the case may be, by the action of the resilience loss compensating elements, the corresponding discharge ports of the chamber. Depending on the direction of rotation of the pump impeller, the cleaning liquid will cause the resilient deformation of the corresponding diaphragm, allowing the cleaning liquid to flow through the associated discharge passage. When the impeller stops rotating, the diaphragm reestablishes the sealing action on the discharge port.

    • A windscreen washer pump has a casing which may be connected to a cleaning liquid reservoir and formed by a body member and by a cover which may be connected together. The body member is formed with a tubular suction extension, a pumping chamber and a discharge nozzle and a bent tubular extension attached to the cover by means of a passage member. The casing accommodates an impeller, a sealing joint and an electric motor for driving the impeller. The bent tubular extension contains a float which may make an electrical circuit across the free ends of the conductors housed in the passage member and connected to the terminals of the cover, and a stop valve preventing the liquid from flowing to the float chamber when the impeller is operating.
