SYSTEM AND METHOD FOR REDUCING VIBRATION IN A WINDSHIELD WASHER PUMP

摘要

This invention includes a system and method for maintaining an impeller (30) in a centrally located position in a pump cavity defined by an impeller housing (34) in order to reduce noise and vibration between the impeller (30) and the impeller housing (34). The system and method include situating an end or tip (42) of the impeller (30) in a bearing (44) which is integrally molded onto the impeller housing (34) at an inlet end (35) thereof. Another embodiment illustrates the use of a locator integrally molded at the inlet end of the impeller housing and which cooperates with a locating aperture in an impeller end of the impeller to cause the impeller end to be maintained in a substantially centrally located position in the pump cavity defined by the impeller housing.
