Problems solved by technology

[0004] The disadvantage is that the magnets can break if damaged during manufacture or installation and can come out of the buoy
This can cause the buoy to stick and the device to fail

Embodiment Construction

[0018] figure 1 A fluid reservoir 1 for hydraulic fluid, in particular brake fluid, is shown comprising the device known from DE 37 16 135 A1 for monitoring the filling level of the reservoir. The accumulator 1 is fixed, for example, on the master cylinder (not shown) of the motor vehicle brake system, and is connected with a conduit 2, which extends into the interior of the accumulator and is closed at its end towards the interior of the accumulator, making A buoy 3, for example annular, is mounted movably along a conduit 2, preferably of circular cross-section. The buoy 3 has a ring magnet 4 . A tubular sleeve 6 protruding from the bottom 5 of the reservoir 1 and concentrically partially enclosing the conduit 2 serves as a stop for the buoy 3 . This stop defines the lowest position of the buoy 3 inside the reservoir 1 and prevents the buoy 3 from leaving the conduit 2 .

[0019] A bracket 7 is arranged inside the conduit 2, on which a reed switch 8 is fastened. Attached ...

Abstract

The invention relates to a device for monitoring the fluid level of a reservoir (1), in particular a hydraulic brake system of a motor vehicle, comprising a float with a magnet (4) for actuating a switch (8) or a sensor (3). The core of the present invention is that the buoy (3) is designed as a multi-piece structure with a first buoy component (9; 11) and a second buoy component (10; 12), and the magnet (4) is embedded in the two buoy components (9, 10; 11, 12).

Description

technical field [0001] The invention relates to a device for monitoring the fluid level of a reservoir, in particular of a hydraulic brake device of a motor vehicle, comprising a buoy with a magnet for actuating a switch or a sensor. Background technique [0002] In hydraulic motor vehicle brake systems, the required brake fluid is contained in a reservoir, the reservoir level being monitored by means of a magnet for closing a switch contact. If the brake fluid level drops, the switch contacts close. This signal is processed in an electronic controller and can be used as a warning to the driver of the motor vehicle via an indicator light or the like. At this point, it must be ensured that the reservoir is always filled with the minimum amount of brake fluid so that the operation of the brakes is not affected. Typically a container level monitoring device is used in which the float closes the reed contact once the float reaches a predetermined position (switch-on point) whe...
