摘要:
A system for feeding fuel from a supply tank to an internal combustion engine, having a feed unit which is preceded by a disklike fuel filter and followed by an annular fuel filter. For the sake of simplified installation of the feed system in the tank, a common filter housing is provided, with which the feed unit, the upstream disk filter and the downstream ring filter are integrated.

The invention relates to a high-pressure accumulator for fuel injection systems, having a number of line connections corresponding to the number of chambers of an internal combustion engine. The accumulator has an essentially circular cross section delimited by an inner wall. The individual line connections each have a fuel-conveying longitudinal bore and, with the aid of a screw element, are held in a fitting fastened to the outside of the high-pressure accumulator. The screw element presses the respective high-pressure line connection into a seat. The high-pressure accumulator has an oscillation-damping valve integrated into it that includes a closing element, which is acted on by a spring body supported against a shaft connected to the closing element and is optionally supported against the inside of the high-pressure accumulator.

A fuel injection system for internal combustion engines includes including a high-pressure reservoir which is acted upon by fuel at high pressure via a high-pressure feed unit and supplies fuel injectors with fuel. The high-pressure feed unit is assigned a pressure regulating valve which is disposed between a high-pressure side and a low-pressure side and includes a valve element which is triggerable via an electrical final control element. The pressure regulating valve includes a housing component which includes a deformable region by way of which, upon mounting of the pressure regulating valve on a receiving body, a gap L between faces of an electrically triggerable final control element assembly is adjustable.
摘要:
A method and a device for storing and/or reading out data of a fuel metering system, in particular a fuel pump or an injector, as described. Data on the fuel pump and/or the injector is assigned to at least one electronic component. The data is taken into account by a control unit in controlling the fuel metering system. The component is mechanically and/or electrically connected to the control unit during a first interval of time and is mechanically and/or electrically detached from the control unit and/or the fuel metering unit during a second interval of time.

Disposed above a loading section (16), on which horizontally arranged strip-shaped packaging material (P) is longitudinally movable, is a shaping wheel (20), which has an, in relation to the loading section (16), transverse central axis (22) and is rotatable about the latter. The shaping wheel (20) has a cylindrical peripheral surface (24) and contains a plurality of moulds (32) which are disposed at angular intervals, starting from the cylindrical peripheral surface (24), radially in relation to the central axis (22). The peripheral speed of the shaping wheel (20) corresponds to a slip-free rolling of its peripheral surface (24) on the packaging material (P). Each of the moulds (32) contains a piston (50) which is movable back and forth between a retracted position for filling the mould (32) with substance (M) and an advanced position for ejecting the consolidated formed body (F) in a radially outward direction onto the packaging material (P). The shaping wheel (20) travels successively through a filling area (34), in which the moulds (32) are filled with substance (M), a dwell area (36), after travelling through which the substance (M) contained in the mould (32) is a packageable formed body (F), and a deposit area (38), in which each formed body (F) may be deposited from its mould (32) directly on the packaging material (P).

The invention relates to a method for detecting selection of a pump assembly (25, 32), for instance a fuel pump assembly, in which at least two pump assemblies are provided. By means of a control unit (12), the lambda signal is scanned continuously by means of lambda probes (21). As a function of the lambda signal ascertained, the maximum fuel injection quantity is limited to the supply quantity of a fuel pump assembly (25, 32), and simultaneously a limitation of the air quantity to the air quantity corresponding to the maximum fuel injection quantity is effected. The limitation of the maximum fuel injection quantity and of the associated air quantity is effected via a throttle valve element (13.1), which is triggered by the control unit (12).

An apparatus for feeding fuel from a supply container to an internal combustion engine of a motor vehicle is described. The apparatus has a fuel feed unit which on the intake side communicates with a suction container, communicating with the supply container, and on the pressure side communicates with the engine, and having a return line for feeding excess fuel into the suction container. In its bottom region the suction container has a closing element, which is movable between a first position, in which the suction container is opened relative to the supply container, and a second position, in which the suction container is closed relative to the supply container. According to the invention, the closing element has an actuating device, preferably a float body, which in particular at a low or zero fuel level in the supply container keeps the closing element in the first, open position, and which, when at least enough fuel is located in the suction container that the fuel feed unit can still furnish enough fuel to the engine, keeps the closing element in the second, closed position.

A fuel supply system for fuel supply of an internal combustion engine has a fuel supply container, a fuel supply unit having a pressure limiting valve providing an adjustable maximum pressure, a fuel supply conduit having a pressure regulating valve adjustable to an operational pressure for maintaining a regulated operational pressure in the fuel supply conduit, a fuel return conduit adapted to connect the internal combustion engine with the fuel supply container, and a delay valve associated with the pressure regulating valve for loading the fuel supply conduit with an initial pressure which is higher than an operational pressure.
摘要:
A fuel supply device has a container from which fuel is to be supplied to an internal combustion engine, a receptacle, a fuel feeding aggregate arranged on the receptacle, a connecting unit for receiving electrical and hydraulic connecting elements. The fuel container has a lower side provided with an opening, and the fuel feeding aggregate is insertable in the opening of the lower side of the fuel container.
摘要:
An assembly for feeding fuel form a supply tank to an internal combustion engine, with a feed pump which is designed as a flow pump and the disk-shaped impeller of which rotates in rotation in a cylindrical pump chamber delimited by a suction cover and by an intermediate housing bearing on the latter and at the same time feeds fuel from a suction port in a suction cover to a delivery port in the intermediate housing to enlarge the production tolerances of a fit between the suction cover (7) on the intermediate housing, and in order to allow the two pump components to lift off from one another during the operation of the feed pump in order to flush out dirt particles from the pump chamber, the suction cover and the intermediate housing are braced relative to one another by means of a resilient connecting element and the suction cover and intermediate housing are permitted to move relative to each other in order to flush dirt from an area of the pump impeller.
