摘要： An arrangement for pumping fuel out of a supply tank to an internal combustion engine having an electrically driven pumping unit which is disposed in a ram pot inserted into the supply tank. The ram pot is filled with fuel from the tank by means of a jet pump provided on its bottom; the intake opening of the jet pump is preceded by a filter that is formed by at least one ring of teeth axially protruding from the bottom of the ram pot, which enclose an intake chamber into which the intake opening of the jet pump protrudes.

摘要： The device has a feed pump arranged in the supply tank (12), which can be inserted through an opening (20) in the supply tank (12). The opening (20) is closed by means of a closure element (22) on which a pressure regulator is disposed, which is connected with the pressure side of the feed pump and with the internal combustion engine, and which can be connected with a relief chamber (12). The closure element (22) has a base body (30) made of plastic, in which a depression (40) has been formed, which is closed by means of an elastic diaphragm (52), so that a pressure chamber is formed. A connector (45) projects into the depression (40), which is connected with the relief chamber (12) and whose front end (51) can be closed by means of a flattened ball (74), which is movably seated in a support element (70) connected with the diaphragm (52). The diaphragm (52) is clamped between a retaining element (54) and the base body (30), and the ball (74) is pressed with its flattened area (75) against the front end (51) of the connector (45) by means of a pre-stressed spring (60) acting on the diaphragm (52). When a defined pressure is exceeded in the pressure chamber, the diaphragm (52) is lifted and the ball (74) clears the connector (45) and fuel can flow out of the pressure chamber.

摘要： Arranged in the fuel tank is a reservoir into which fuel is pumped by a jet pump connected to a return line from the internal combustion engine. The jet pump has a jet nozzle which is arranged in a holder formed on the reservoir. Between its inlet opening and the propulsion-nozzle opening, the jet nozzle has a bypass opening which is connected to a stub projecting into the reservoir. At its end, the stub is provided with a seat which can be closed by a closing element. Arranged in the reservoir is a leaf spring which is fixed at one end and which presses the closing element onto the seat. Together with the closing element, the bypass opening forms a bypass valve which allows fuel to flow out of the jet nozzle if a certain pressure is exceeded.
