摘要： The invention relates to a device that comprises an accumulator tank (14) disposed in a storage tank (10), in which a delivery system (24) is mounted that delivers fuel to the internal combustion engine (12). A partial amount of the fuel delivered by the delivery system (24) is fed to a jet pump (60) which in turn delivers fuel from the storage tank (10) to the accumulator tank (14). An intake compartment (34) is disposed below the delivery system (24) close to the bottom (18) of the accumulator tank (14), from where the delivery system (24) takes in fuel. A connection of the intake compartment (34) with the accumulator tank (14) is controlled by a float valve (42) that is disposed laterally of the delivery system (24). When the accumulation compartment (14) is full, the intake compartment (34) communicates with the accumulation compartment (14) by way of said float valve so that the delivery system (24) takes in fuel from the accumulation compartment (14). A connection of the intake compartment (34) with the storage tank (10) is controlled by a non-return valve (52) that is disposed on the bottom (18) of the accumulator tank (14). When the accumulation compartment (14) is empty, the intake compartment (34) communicates with the storage tank (10) by means of said non-return valve so that the delivery system (24) takes in fuel from the storage tank (10).

摘要： The invention relates to a pressure regulator for a fuel supply system of an internal combustion engine for regulating a fuel pressure. Said regulator comprises a valve, which contains a valve ball that is displaced into a closing position against a valve seat by the action of a valve plate spring. The invention is characterised in that one section (31) of a hemisphere, facing towards the valve plate spring (16), of the valve ball (18) projects into a recess (37) that is allocated to the valve plate spring (16). This improves the acoustic and regulatory behaviour of the pressure regulator.

摘要： The invention relates to a device for supplying fuel from a fuel tank. Said device comprises a reserve container (11) which can be inserted into the fuel tank (10) and brought into an end position, and a fuel feed pump (20) housed in said reserve container (11). To ensure that the reserve container (11) is automatically emptied when the supply device is dismantled said reserve container (11) has a drain opening (28) which is closed off by blocking elements (30) when the reserve container (11) is in its end position in the fuel tank (10) and opened to allow the fuel to be released when the reserve container (11) leaves its end position.
