compensating reservoir for brake fluid, provided with an alarm device controlling the level of brake fluid

摘要

Compensating brake fluid reservoirs with a brake fluid alarm device are required for master cylinders of hydraulic brake systems in automotive vehicles. A float chamber, which is disposed in a compensating reservoir and surrounds a float, is defined by a tubular body suspended from an upper end of the reservoir and a bottom element. After insertion of both parts into the reservoir the bottom element cooperates with the lower end of the tubular body such that the float chamber is closed at least to such an extent that the inflow and outflow of the fluid therefrom is inhibited in order to achieve a damping effect. This enables a quick immersion of both parts into the filled reservoir without brake fluid leaking from the reservoir.
