Embodiment Construction

[0017] Referring now to FIG. 1 , automotive glass, such as a windshield 10 , is washed by a washer fluid 12 sprayed onto the glass through a pair of nozzles 14 and 16 . The nozzles 14 and 16 are connected in series via a fluid line 18 , which in turn is supplied with washing liquid from a water storage container 20 . The reservoir 20 is connected to a wash pump 22 which uses an impeller 23 to pump the wash liquor 12 through a first fluid line in the form of a first hose 24 to a fluid coupling 26 constructed in accordance with the principles of the present invention. Fluid coupling 26 includes a filter 28 for removing impurities, including impeller 23 passing through wash pump 22 to hose 24 . Filter 28 is preferably cylindrical and is preferably made of plastic or stainless steel. A second fluid line in the form of a second hose 29 conveys the filtered washing liquid 12 to the fluid line 18 connected to the nozzles 14 and 16 .

[0018] Referring now to FIG. 2, according to th...

Abstract

An automotive glass washer arrangement includes a washer pump having an outlet in fluid connection with at least one automotive glass washer nozzle. The arrangement comprises a fluid coupling having a female element with a chamber therein. A replaceable filter is disposed in the chamber. The fluid coupling further has a male element connected to the female element wherein the female element is in fluid communication with the washer pump and the male element is in fluid communication with the at least one nozzle. In a preferred embodiment, the female element is connected to the washer pump with a first hose and the male element is connected to the washer nozzle with a second hose.

Description

technical field [0001] The invention relates to an automobile glass washing device. More specifically, the invention relates to such a device including a filter. Background technique [0002] In designing a windshield washer system, there is a need to improve reliability. In addition, there is a need to reduce costs by reducing labor costs and component costs, and also to reduce packaging space within the vehicle. [0003] The vehicle glass washing device includes a water storage container, a washing pump and at least one nozzle for spraying washing liquid on the glass. Typically, a windshield washer uses a pair of nozzles to spray the windshield and a rear window washer uses a single nozzle which may have a pair of outlets. To prevent nozzle clogging by particulate material, current arrangements use a filter arranged upstream of the wash pump impeller. These filters do not filter out impeller material that may be present. Additionally, during initial start-up, start-up...
