Embodiment Construction

[0026] figure 1 Pump 12 of a windshield washer system in a wiper system 48 of a motor vehicle that delivers washer fluid from a (not shown) storage container is shown. Of the wiper device 48 comprising two wiper arms and wiper blades 16 , 26 fastened to the wiper arms, only the driver-side wiper blade 16 and the passenger-side wiper blade 26 are shown. The supply lines 14 leading to the respective wiper blades 16 , 26 are connected to the pump 12 via a common line section 50 . If the pump 12 builds up a certain cleaning fluid pressure in the common line section 50 , this pressure is exerted in the individual delivery lines 14 .

[0027] The wiper blades 16 , 26 are connected to the respective (not shown) wiper arm via respective connecting pieces 52 . Each delivery pipe 14 leads into the connecting piece 52 and there at the branch point 36 (refer to image 3 ) are connected to the respective two distribution pipes 22, 24, 38, 40.

Abstract

The invention relates to a wiper arrangement (48) with an associated windscreen washing system for a motor vehicle. The windscreen washing system comprises a washing liquid supply pipe (14) leading to outlets. The outlets are preferably arranged on the wiper blade (16, 26) and can consequently be moved together with a corresponding wiper arm of the wiper arrangement (48). A coupling part (52), by means of which the wiper blade (16, 26) is connected to the respective wiper arm, and which moves with the wiper arm as the latter moves, has switching valves. The discharge of washing liquid from the outlets can be controlled by means of the switching valves. Furthermore, the invention relates to a method for operating such wiper arrangement (48).

Description

technical field [0001] The invention relates to a wiper device for a motor vehicle, which has an associated windshield washer device. The windshield washer device comprises a washer fluid supply line leading to at least one water outlet, wherein the at least one water outlet can be moved together with a corresponding wiper arm of the wiper device. The invention also relates to a method for operating such a wiper device. Background technique [0002] DE 3643476A1 describes a lift-type wiper device for automobiles, wherein the washer fluid nozzles arranged on the wiper arm move together with the wiper arm when it moves. In this case, the drive shaft of the wiper arm has an axial bore which is divided by an axial web into two feed channels for the washer fluid which are separate from one another. The cleaning fluid can be distributed to any delivery channel by means of a changeover switch arranged in the connecting piece for connecting the hose line. The delivery channel the...
