摘要： An arrangement for cleaning fuel has a housing, a deflecting member in the housing and forming an annular gap extending between a fuel inlet and a fuel outlet and also a water storing chamber separated from the fuel inlet, and electrical water-level-indicating device including a rod-shaped impulse generator extending through the deflecting member into the interior of the water storing chamber and a one-piece float located in the water storing chamber and cooperating with the impulse generator, and a water discharge device provided with a throttle valve which includes a water discharge opening in the bottom of the housing and a throttle valve member cooperating with the water discharge opening, wherein the float forms the throttle member and has a guide opening and a closing surface cooperating with the water discharge opening, the guide opening goes completely through the float and the rod-shaped impulse generator extends into the throughgoing guide opening in condition of the closed throttle valve so as to guide the float in the housing, and the closing surface and the water discharge opening are radially offset relative to the throughgoing guide opening.

摘要： In a device for temperature responsive switching of overflow fuel quantities from a diesel fuel injection pump to a fuel supply tank or a filter of a fuel supply system a switching valve, arranged between the fuel injection pump and the tank, is actuated by a bimetallic element. Parallel to the switching valve is provided a throttle for continuous air venting. A pressure control valve with a low opening pressure is installed in the connection between the switching valve and the filter. The heated overflow fuel quantities are mixed with cool fuel from the tank and therefore the danger of clogging of the filter, which could be caused by paraffin separation, is substantially reduced.

摘要： Corrosion of a water sensor resulting from the passage of considerable electric current through it while it is in contact with water is prevented in a motor fuel filter equipped for water separation by interrupting or greatly reducing the current passing through the sensor after the sensor has given a signal indicating the presence of water in sufficient quantity to require draining soon. The warning provided to the vehicle driver is maintained thereafter either by a signal storage circuit (flipflop) or by causing current diverted from the sensor to flow through a substitution resistor or a shunt transistor.
