Abstract

In a brake fluid container for hydraulic motor vehicle brake systems having a housing with a fill connector a container cap closing off the fill connector, a filling filter suspended in the fill connector and protruding into the housing interior, and a level switch secured to the container cap for indicating a minimum allowable fill level in the housing in order to attain extensive damping of a float of the level switch with respect to fluid fluctuations caused by vehicle behavior, the filling filter is embodied as a closed float chamber, extending to below the minimum allowable fill level in the housing with guides for the float. On its lower end, the filling filter is provided with a throttle bore located near the minimum allowable fill level and in a region near the maximum fill level, it is provided with filter windows for the sake of rapid filling of the housing with fluid.
