A fuel delivery unit of a motor vehicle comprises a prefilter arranged inside a swirl pot, said prefilter having a filter element, and at least one connection piece for connecting a supplementary filter element. The at least one connection piece, in its initial condition, is closed, and is opened when the supplementary filter element is attached. The invention allows the fuel delivery unit to be adapted to projected filter surfaces of the prefilter.

Fuel delivery unit

A device for collecting fuel in a fuel tank of a motor vehicle having a prefilter arranged inside a swirl pot. The prefilter has a section rising from a horizontal plane and a section lying in the horizontal plane. The sections of the prefilter are produced as one piece and are connected to the swirl pot. The prefilter has an especially large surface.

Device for controlling fuel in a fuel tank

A fuel delivery unit for a motor vehicle, wherein a swirl pot has a base formed from an upper part and a lower part, and an outer wall connected to the base, forming a seal. The upper part and the lower part bound fuel-delivering regions of a suction jet pump and of a section of a feed line. This arrangement allows the fuel delivery unit to be produced at particularly low cost.

Fuel delivery unit for a motor vehicle

A delivery unit for delivering fuel in a fuel tank comprises a prefilter and swirl pot which are produced as one piece. The prefilter is produced during die-casting of the swirl pot. The invention allows the delivery unit to be produced in an especially inexpensive manner.

Delivery unit for delivering fuel

A feed unit for feeding fuel has a housing formed integrally with the casing of a swirl pot, the housing comprising a fine filter. The fine filter is configured open toward one side and is closed by a cover. The cover is formed integrally with a base plate sealing the casing of the swirl pot. As a result, the feed unit has a particularly low number of components to be assembled and can be produced in a particularly cost-effective way.

Feed unit for feeding fuel

Disclosed is a pressure regulator for a fuel supply unit of a motor vehicle comprising a valve for joining a connection to an outlet above a designated pressure in the connection, a valve body and a valve seat, and a spring element for prestressing the valve body against the valve seat, characterized in that the valve body is designed as a sheet-metal part.

Pressure regulator for a fuel supply unit

Disclosed is a pressure regulator for a fuel supply unit of a motor vehicle and method for production of a pressure regulator. The pressure regulator comprises a valve for producing a joining of a connection to an outlet above a designated pressure in the connection, a movable piston and a membrane, which is held on a fixed annular element, for sealing the piston in relation to the annular element, characterized in that the membrane is welded to the annular element.

A feed unit has a surge chamber, a fuel pumpwhich is arranged in the surge chamber, and a pump holder, the fuel pumpbeing arranged in the pump holderand the pump holderbeing fastened in the surge chamber. The pump holderhas at least two rodswhich are fastened in the surge chamber, the rodsbeing connected to a mountfor the fuel pump

Feed unit

In a feed unit for feeding fuel from a fuel container of a motor vehicle a surge part () has a base plate () and an adjoining tubular section (). The base plate () is fabricated in one piece with a nozzle () and a mixer pipe () of a suction jet pump () and has receptacles () for a fine filter () and for supporting rods () of a fuel pump (). The feed unit is of particularly simple design as a result of this and can be fabricated in a cost-effective way.

The invention relates to a filling level sensor for a fuel tankcomprising a ceramic mounting platewith a resistance networkarranged thereon and a contact structurefor the detection of an electrical filling level signal, and a coverconnected to the mounting platethe coverand the mounting plateforming a housingThe coveris strengthened in its edge area.

In a fuel tank for a motor vehicle, an intermediate tank is arranged for the intermediate storage of fuel fed via a plurality of suction jet pumps. The intermediate tank distributes the fuel to a plurality of baffles having feed units. One of the feed units is thereby prevented from running dry in the event of transverse accelerations of the fuel tank.

The invention relates to a magnetic passive position sensor, comprising a substrate ( ) with a resistance network ( ) which is arranged on this substrate ( ) and is assigned a contact spring structure ( ), which can be deflected under the action of a permanent magnet ( ), with electrical connection between the resistance network ( ) and the contact spring structure ( ) being established by contact which is dependent on the position of the permanent magnet ( ), the contact spring structure ( ) and the resistance structure ( ) being enclosed in a sealed housing ( ) and the permanent magnet ( ) being movable outside the sealed housing ( ) and having flux concentration, structure associated therewith.

Passive magnetic position sensor

A pressure regulator has a closing member which controls a pressure-medium inlet and on which is supported a valve spring arranged in a spring can. The spring can includes a casing part and of a lid. The valve spring is supported with one end against the lid. The lid is pushed into the casing part until the necessary spring force is set exactly and is then connected to the casing surface of the casing part by means of radial indentations.

Pressure regulator

The humidifying device for a fuel cell has a membrane, one side of which is exposed to cathode exhaust gas of a fuel cell for extracting water vapor from the exhaust gas. A connecting element connects the other side of the membrane to an anode or cathode gas supply to the fuel cell. In operation, water vapor permeates through the membrane and passes on through the connecting elements to humidify the gas being supplied to the fuel cell. A vacuum pump may additionally be provided to enhance the extraction of water vapor from the exhaust gas. A no metering unit allows accurate metering of the humidity of the cathode or anode gas supply.

Humidifying device for a fuel cell, method for humidifying a fuel cell membrane and fuel cell

A fuel tank, in particular for fuel-cell systems, which can feed fuel into a system via a mechanism without a pump or the like. This is achieved by a fuel tank with a fuel cavity of variable size and a mechanism for compressing the fuel cavity. The fuel cavity is preferably bounded by a cylindrical inner wall of the fuel tank, by a circular end surface of the fuel tank and by a circular, displaceable intermediate wall. The intermediate wall is forced essentially in the direction of the fuel cavity by a spring and has a form fit with the cylindrical inner wall. A feed device and a discharge device allow incorporation in a fuel line. The system also includes a control device and a method for this fuel container, which is thus enabled to have the following operating states: A. fuel-cell system is switched on: discharge valve open, feed valve closed; B. fuel-cell system is in operation: discharge valve open, feed valve open; C. fuel-cell system is switched off: discharge valve closed, feed valve open; and D. fuel-cell system is off, fuel cavity is full: discharge valve closed, feed valve closed.
