摘要:
The fuel delivery device (12) has a receptacle (16) arranged in a storage tank (10) and a delivery unit (20) delivering fuel from the receptacle (16) to the internal combustion engine (14) of a motor vehicle. Further, there is provided at least one suction jet pump (40) which delivers fuel from the storage tank (10) into the receptacle (16). The suction jet pump (40) is fastened to an upper edge area (17) of the receptacle (16) as a separate constructional unit. The suction jet pump (40) is formed by a constructional unit having a propelling nozzle (41), a connection (43) for a propelling line (44), which connection (43) opens into the propelling nozzle (41), a mixing pipe (42) following the propelling nozzle (41), and a connection (45) for a suction line (46), which connection (45) opens into the mixing pipe (42). Two walls (48) located at a distance from one another project downward from the constructional unit (40), and the constructional unit (40) is mounted on the edge (17) of the receptacle (16) from the top, wherein the edge (17) of the receptacle (16) is introduced between the two walls (48). The suction line (46) connected to the suction jet pump (40) opens into the storage tank (10) remote of the receptacle (16).

A device for supplying an internal combustion engine with fuel has a supply container from which the fuel is supplied and having an opening, a feed pump arranged in the supply container and insertable into the supply container through the opening, a closure part for closing the opening of the supply container, a pressure regulator arranged on the closure part and having a pressure chamber with a connection to a pressure side of the feed pump, to an internal combustion engine and to an unloading chamber, the closure part having a flange-shaped base body which closes the opening and is provided with a depression, a pipe formed of one piece with the body for forming a connection of the pressure chamber to the unloading chamber and extending into the depression, an elastically deformable diaphragm group which closes the depression for forming the pressure chamber, the pipe having a seat with which diaphragm group at least partially directly cooperates, a spring loading the diaphragm group toward the pipe so that during the exceeding a predetermined pressure in the pressure chamber the pipe for connecting the pressure chamber with the unloading chamber is released, the diaphragm group being mountable to the base body, a holding element arrangeable on the closure part, and an insert part engageable with the spring and movable axially relative to the holding element.
摘要:
A delivery device for fuel to an internal combustion engine, which includes a fuel reservoir. After the engine is shut off or in the event of an accident, there is the danger that the pressurized fuel present in the fuel reservoir will escape from the delivery device. A blocking device is provided on the fuel reservoir, which after the engine is shut off or after an accident, the blocking device engages with an actuation rod that is provided with detent teeth, by means of an electromagnetically actuated locking pin and thus prevents a force impingement of a compression spring on the movable wall of the fuel reservoir. By use of the blocking devices the pressure in the fuel line is completely reduced even after the escape of small fuel quantities. The delivery device is suited for mixture-compressing internal combustion engines with externally supplied ignition.

In a feed unit for delivering fuel from a supply tank (10) with a filter cup (13) having a central chamber (14) and an annular chamber (15) enclosing the latter, with a filter cover (30) which closes the annular chamber (15) and which contains an inlet duct (36) to the annular chamber (15) and an outlet duct (37) from the annular chamber (15), and with a feed pump (22) which is inserted in the central chamber (14) and which projects with a suction connection piece (26) through an opening (20) into a suction space (19), assembly is simplified and manufacturing costs are reduced in that the clearance diameter of the central chamber (14) is dimensioned so as to be greater than the outer diameter of the pump housing (23), and an axially projecting pressure connection piece (27) is formed at the other end side of the housing (23) remote of the suction connection piece (26) and a mounting cap (38) which engages over the pressure connection piece (27) is formed at the filter cover (30). A flexible sleeve (39, 28) is inserted between the pressure connection piece (27) and the mounting cap (38) on the one hand and the suction connection piece (26) and opening (20) in the cup base (131) on the other hand and serves for the sealing, support and noise decoupling of the feed pump (22) in the filter cup (13).
摘要:
The invention relates to a device for a fuel supply system, having a pressure chamber that communicates with a fuel connection, and having a diaphragm built in on its outer peripheral region in a basic body which partitions off the pressure chamber, wherein the diaphragm is fastened in the peripheral region with a spring ring that is under initial tension and is retained on the basic body.

The invention is directed to an arrangement for controlling an actuable element in a motor vehicle equipped with a drive unit. The arrangement includes an actuable element movable over a maximum possible operating range between two outermost limits including a normal operating work range within the limits; an electrically actuable actuating device for controlling the actuable element; a control unit for generating actuating signals for controlling the actuable element and for supplying the actuating signals to the actuating device; the control unit is adapted to generate the signals so as to cause the actuable element to move over most of the maximum possible operating range in a manner to prevent jammings with the actuable element being moved outside of the normal operating work range at least beyond one end of the normal operating work range; the actuable element being moved starting from a desired position for every possible direction of movement; and, the actuable element being moved at least at one of the following times: ahead of the start of the drive unit and after the drive unit has been switched off.

摘要:
A control device for the control of an opening cross-sectional area of a flow duct, in particular for internal combustion engines, comprising three sub-assemblies, an actuator housing with flow channel and setting window, a rotor with a rotary valve for controlling the window opening, and a drive housing with stator and stator winding. For setting a required air gap between the rotary valve and the setting window, a control section of the rotary valve covering the setting window is designed as a cone envelope segment, and is inclined at an acute angle to the rotor axis. The window lying in a cone envelope plane is located at the same angle of inclination. By means of a spacing disk between the rotor, with the rotary valve affixed thereon, and the actuator housing, the air gap is set and fixed as required.
