Problems solved by technology

[0012] However, if so much operating fluid is withdrawn from the tank interior that the filter body interior is no longer completely filled with operating fluid, there is also the risk when suctioning the operating fluid from the filter body interior that in the presence of In the above-mentioned driving situation during prolonged acceleration phases, the operating fluid is squeezed and remains squeezed away from the suction opening of the suction line which is remote from the delivery pump
The extraction of the filtered operating liquid during the acceleration phase is then no longer guaranteed as far as possible, or at least not continuously

Embodiment Construction

[0034] exist figure 1 Here, the liquid tank of the motor vehicle-tank assembly 11 according to the present invention is denoted as a whole by 10 . The liquid tank 10 preferably includes an upper shell part 12 having a filling opening 14 with a flanged edge 16 surrounding the filling opening 14 . A filling line can be connected to the flange edge 16, e.g. figure 1 Fill tube not shown. The filling opening 14 , or if a filling line is present, can preferably be closed by a cover 17 .

[0035] The liquid tank 10 also includes a lower housing part 18 which has a mounting opening 20 with a filter body 22 which is inserted into the mounting opening 20 and closes it.

[0036] The upper shell part 12 and the lower shell part 18 are preferably joined to each other, eg glued or welded, along respective circumferential joint flanges 24 and 26 . Joint flanges 24 and 26 meet along joint surface 28, which is preferably planar.

[0037] The tank 10 has a tank shell 30 which encloses a ta...

Abstract

The invention relates to a motor vehicle-tank assembly for storing and discharging an operating liquid, encompassing: a tank shell enclosing a tank interior; a conveying pump; a filter body at least partly accessible from the tank interior; and an intake conduit, the filter body having a body shell that encloses a filter body interior; at least a portion of the body shell encompassing a liquid-permeable filter material through which operating liquid in the tank interior can flow from outside the filter body into the filter body interior; the intake conduit connecting an intake side of the conveying pump to the filter body interior; arranged in the filter body interior, in the region of an intake opening of the intake conduit, is a baffle configuration that is embodied, as compared with anidentically constructed filter body having no baffle configuration, to impede a movement of operating liquid away from the intake opening.

Description

technical field [0001] The invention relates to a motor vehicle-tank assembly for storing and dispensing operating fluids, comprising: a tank casing enclosing a tank interior; a delivery pump; a filter body at least partially accessible from said tank interior; and a pump Suction line, wherein the filter body has a main body housing surrounding the inner space of the filter body, wherein at least one section of the main body housing comprises a liquid-permeable filter material, the operating liquid in the inner space of the tank passes through The filter material can flow from outside the filter body into the filter body interior, wherein the suction line connects the suction side of the delivery pump to the filter body interior. [0002] Such a motor vehicle box assembly is known from DE 10 2012 003 121 A1 or DE 10 2010 014 314 A1. [0003] The invention also relates to a filter body comprising a main body housing surrounding the interior space of the filter, wherein the mai...
