Abstract: A gas turbine includes a supporting structure which concentrically surrounds a hot gas path and is shielded with respect to the hot gas path by an annular heat shield (15?), which heat shield (15?) includes a multiplicity of segments which are arranged one behind the other in a circumferential direction and which in each case butt against one another in the circumferential direction so as to form a gap, seals (16?), being arranged for sealing off the gaps between the segments butting against one another, the seals having thin elongate sealing strips (23), which are accommodated in corresponding sealing slots (19), delimited transversely with respect to the longitudinal direction by a wall (25), in the mutually opposite end faces of the segments of the heat shield (15?) which butt against one another.

Abstract: Disclosed is a fuel pump which is embodied as a side channel pump and is used for conveying fuel into a fuel reservoir of a motor vehicle, and in which a partially annular duct (13) that extends to a discharge duct (8) is configured in a continually expanding manner. A partially annular duct (12) that is connected to an intake duct (7) tapers in the direction of flow. Blade chambers (10) that are disposed within an impeller (6) form a conveying chamber (14) along with the partially annular ducts (12, 13). Said conveying chamber (14) extends from the intake duct (7) to the discharge duct (8) and is provided with a constant cross section such that the impeller (6) is continuously penetrated by a flow.

Abstract: A sealing arrangement has two bodies with two end faces which extend along a longitudinal axis, adjoin one another while forming a gap, the width of which can vary between zero and a maximum width. The gap is covered by a sealing strip which lies transversely to the gap, extends along the longitudinal axis and is mounted with clearance in two opposite grooves of a predetermined depth. In such a sealing arrangement, an increased maximum width of the gap is made possible by the sealing strip having a basic width transversely to the longitudinal axis, this basic width being less than or equal to twice the depth of the grooves, and by the sealing strip is constructed to prevent the sealing strip from slipping out of the grooves if the sum of the maximum width of the gap and the depth of the grooves is greater than or equal to the basic width of the sealing strip.

Abstract: The invention relates to a delivery unit comprising a vertical ejector. A deviation, which is manufactured in one piece with the cover of a fuel pump, is located above the outlet of a mixing tube. The delivery unit is thus extremely cost-effective to produce.

Abstract: The invention relates to a connection (7) of a fuel supply device in a motor vehicle, which is characterized in that a corrugated hose (5) is held in a peripheral groove (10) of a connection piece (8) by means of a glue (12) and in that the groove (10) protrudes from an undulation of the corrugated hose (5). The corrugated hose (5) can thus be connected to the connection piece (8) with very little effort. The connection (7) is also inexpensive to produce.

Abstract: In a sealing arrangement, in particular for the blade segments of gas turbines, two bodies, with two end faces which extend along a longitudinal axis, adjoin one another while forming a gap, the width of which can vary between zero and a maximum width. The gap is covered by a sealing strip which lies transversely to the gap, extends along the longitudinal axis and is mounted with clearance in two opposite grooves of a predetermined depth. In such a sealing arrangement, an increased maximum width of the gap is made possible by the sealing strip having a basic width transversely to the longitudinal axis, this basic width being less than or equal to twice the depth of the grooves, and by the sealing strip having additional means which prevent the sealing strip from slipping out of the grooves if the sum of the maximum width of the gap and the depth of the grooves is greater than or equal to the basic width of the sealing strip.

Abstract: In a feed pump (2), guide vanes (9) fastened on a driven impeller (7) project into a recess (11) of a molding (8) annularly surrounding the impeller (7). The guide vanes (9) are located with a slight clearance opposite the wall of the recess (11). The guide vanes (9) can thereby have a particularly large surface. Moreover, a depositing of dirt in the radially outer region of the impeller (7) is avoided.

Abstract: A combustion boiler for burning fuel and producing heat to generate steam. A method of minimizing discharging of nitrogen oxides from a combustion boiler comprising the steps of spraying a reducing agent into an overfire air stream and supplying the overfire air stream to the combustion boiler. Vaporizing the sprayed reducing agent at least within about 0.1 seconds of the sprayed reducing agent entering the combustion boiler and reacting the vaporized reducing agent with the nitrogen oxides within the combustion chamber to reduce the nitrogen oxides and minimize discharge of nitrogen oxides from the combustion boiler.

Abstract: The invention relates to a pump unit arranged in an inner tank (3) of a fuel tank, comprising a fuel pump (5) which is used to pump fuel to the internal combustion engine of a motor vehicle; an ejector pump (21) which is connected to the fuel pump (5) and used to pump fuel out of the fuel tank into the inner tank (3); and at least one filter element (20:31) which is used to filter fuel, wherein a housing part which is connected to the fuel pump (5) is provided with at least one channel (30;33;35;47) for guiding said fuel. In order to simplify the structure of the pump unit (2) and to enable substantial pre-assembly, the housing part (24;40) is configured in such a way that it can hold the at least one filter element (20;31), and the channel (30;33;35;47) is exclusively guided inside the housing part (24; 40) from the ejector pump (21) and/or the fuel pump (5) to the filter element (20;31).

Abstract: A device for setting the gap dimension for a turbomachine, in particular a gas turbine, with heat accumulation segments which are arranged on the guide-vane carrier of the rotor arrangement. At least one drive device projects radially through the turbine casing and the guide-vane carrier and is operatively connected kinematically to at least one heat accumulation segment and which, when actuated, causes a radial spacing of the heat accumulation segment. The heat accumulation segment has, in the flow direction of the turbomachine, a conical contour facing the rotor arrangement and is arranged so as to be displaceable parallel to the flow direction, and in that the drive device is connected to the heat accumulation segment directly or via an eccentric unit, in such a way that, when the drive device is actuated, the heat accumulation segment is displaced, with the result that a radial spacing between the heat accumulation segment and the moving-blade tips can be set.
