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.

Abstract: A fuel injection pump for Diesel engines in which a rotating and reciprocating piston pressurizes and distributes fuel to individual pressure lines leading to the injection valves of the engine. In order to change the timing of injection with respect to the engine cycle, there is provided a mechanism to change the relative angle between the pressurizing piston and its drive means, which runs in synchronism with the engine. The mechanism operates hydraulically and is affected by the fuel pressure in the sump of the injection pump. There is also provided a hydraulic control valve mechanism which permits varying amounts of fuel to flow back from the sump to the low pressure side of the fuel delivery pump, thereby changing the injection timing. A primary control valve adjusts the sump pressure on the basis of engine speed while a secondary control valve adjusts the sump pressure on the basis of engine temperature in order to adapt the timing of fuel injection to engine starting and engine warm-up.

Abstract: An improved rpm regulator for a fuel injection pump associated with an internal combustion engine. The regulator includes an intermediate lever, a fuel quantity control sleeve conncted to the intermediate lever, a regulating spring connected to the intermediate lever, a device for generating an rpm signal and applying a force corresponding therewith through the intermediate lever to the fuel quantity control sleeve in opposition to a force exerted by the regulating spring, a control lever, an adjustable stop mounted to the housing and a biasing spring. The intermediate lever is mounted to the control lever which in turn is mounted to the pump housing and is biased against the adjustable stop by the biasing spring.
