The invention relates to a toothed belt () with two mutually oppositely arranged running surfaces (), wherein, on the running surfaces (), there are arranged toothings () arranged obliquely with respect to the axial direction (X), wherein the obliquity is defined in each case by helix angles () between the axial direction (X) and the direction of the tooth flanks of the respective toothings (). It is provided that the helix angle () of the first toothing () is oriented oppositely to the helix angle () of the second toothing ().

Toothed belt comprising running surfaces provided on opposite sides and having tooth systems, the helix angles of the tooth systems being oriented in opposite directions, and associated toothed belt gear

An apparatus is provided for measuring a torque in a force-feedback actuator for a steer-by-wire steering system has a housing element, a control unit, a drive apparatus, and a transmission apparatus to be coupled to a steering device. At least one motion sensor detects a motion of the transmission apparatus relative to the housing element and provide a motion signal resulting from the motion to the control unit. The transmission apparatus is coupled to the housing element by way of at least one reset-reversible adjusting device which has at least one mechanical property. A torque of the transmission apparatus, and thus of a connectable steering device, may be ascertained by the control unit using the at least one mechanical property, which has at least one changing state value during the movement of the transmission apparatus, in combination with the motion signal.

In a feed pump (), guide vanes () fastened on a driven impeller () project into a recess () of a molding () annularly surrounding the impeller (). The guide vanes () are located with a slight clearance opposite the wall of the recess (). The guide vanes () can thereby have a particularly large surface. Moreover, a depositing of dirt in the radially outer region of the impeller () is avoided.

Delivery pump

The invention relates to a pump unit arranged in an inner tank () of a fuel tank, comprising a fuel pump () which is used to pump fuel to the internal combustion engine of a motor vehicle; an ejector pump () which is connected to the fuel pump () and used to pump fuel out of the fuel tank into the inner tank (); and at least one filter element () which is used to filter fuel, wherein a housing part which is connected to the fuel pump () is provided with at least one channel () for guiding said fuel. In order to simplify the structure of the pump unit () and to enable substantial pre-assembly, the housing part () is configured in such a way that it can hold the at least one filter element (), and the channel () is exclusively guided inside the housing part () from the ejector pump () and/or the fuel pump () to the filter element ().

The invention relates to a filter module () for a fuel conveying unit () comprising a fuel pump () with two pump chambers () which are independent of each other. A common filter area () is provided for the inlet areas () of the pump chambers (). The filter module () has a connector () which can be inserted into a recess of a housing part (). The configuration of the filter module () is particularly economical as a result.

A valve for a fuel delivery unit has a counterholder pressed into a housing. A spring is supported on the counterholder and is intended for prestressing a closing part against a valve seat. The valve according to the invention can be fitted in a particularly simple manner.

Valve for a fuel delivery unit

An ejector pump for a delivery unit provided in a fuel tank of a motor vehicle has a nozzle produced integrally with a mixing tube. The mixing tube is shaped in the form of a tubular cylinder, so that virtually the entire ejector pump may be produced from plastic in a mold allowing axial demolding. The nozzle is therefore aligned,exactly with respect to the mixing tube. The ejector pump consequently has a particularly high efficiency.

Ejector pump

An electric motor for a fuel pump wherein fuel flows through the pump, includes spring elements provided for holding magnetic shells in the stator have a face which points toward a rotor and is flush with the magnetic shells. Turbulence in the flow of the fuel within the electric motor are thereby kept particularly low. The pressure loss during the flow through the electric motor thus becomes lower. The pump according to the invention consequently has high efficiency.

A side-channel pump includes guide means for the radial and/or axial guidance of an impeller, the guide means being arranged in the radially outer area of the impeller. The guide means include guide surfaces arranged on the impeller at an intended angle to the ends of the impeller. The frictional losses of the side-channel pump are thereby kept particularly low.

Side-channel pump

A feed pump designed as a side-channel or peripheral pump has two rings of guide vanes arranged in an impeller and concentrically enclosing one another. The sides of the guide vanes facing the intended direction of rotation of the impeller are inclined at an angle relative to the axis of rotation of the impeller. The angles of the guide vanes in a radially outer ring of guide vanes are larger than the angles of guide vanes in a radially inner ring of guide vanes. This arrangement allows the impeller to be produced in an injection mold in an especially cost-effective manner.

Feed pump

In a feed pump designed as a side-channel pump, an impeller is held so as to be slightly pivotable with respect to a shaft about an axis running transversely to the shaft. The impeller is thereby adaptable to tolerances of a casing. Rubbing of the impeller on the casing is also prevented as a result. The feed pump consequently generates a particularly low level of noise.

A feed pump designed as side-channel pump has a shaft for a rotationally fixed connection to an impeller. Two flattenings are arranged on the shaft so that they are nonparallel to one another. The impeller is thereby mountable on the shaft only in an intended position so that the impeller is rotated in an intended direction of rotation in a casing. The feed pump may therefore be assembled in a particularly simple way.

A feed pump includes an impeller with two rings of guide blades delimiting blade chambers. The rings of guide blades concentrically surrounding one another and have different angular intervals between guide blades. The angular intervals between the guide blades of each ring vary within a range of values and ranges of values of each ring of guide blades is different to avoid the additions of noise emissions the feed pump consequently has noises which cause particularly little disturbance.

A feed pump includes two feed chambers one surrounding the other and arranged at different axial levels from an electric motor driving the feed pump. A radially inner feed chamber of the two feed chambers is arranged for filling a baffle of a fuel tank of a motor vehicle. The radially outer feed chamber is arranged for suctioning in fuel from the baffle. The feed pump is of particularly compact design and the radially inner feed chamber is arranged at a low level in the baffle.
