  • Patent number: 6508414
    Abstract: In a window washer nozzle of a window washer apparatus, washer liquid in a vertical liquid pipe is introduced into a horizontal liquid pipe through a filter and sprayed out from an orifice to a windshield. The filter is integrally molded in a coupling portion of the first and the second liquid pipes. An opposed wall of the filter is opposite to an inlet of the horizontal liquid pipe with a space L through which the washer liquid flows into the horizontal liquid pipe. The space L is smaller than a bore size W of the orifice. Therefore, foreign materials in the washer liquid larger than the bore size W are blocked at the filter, thereby restricting clogging of the orifice.

A passage passes through the nozzle. A partition defines four injection ports in the passage. The partition includes a generally triangular guide, which increases in dimension toward the injection ports, and a horizontal partition, which intersects the triangular guide. Two inclined guide surfaces of the guide guide the flow of cleaning liquid. The location of the maximum dimension of the triangular guide is located inward of the imaginary projection of the passage.
