摘要： A motor vehicle fuel pump including an electric motor, a high pressure pump, and a low pressure pump having a side channel pumping stage for pumping fuel from a fuel tank to a reservoir and a regenerative turbine pumping stage for pumping fuel from the reservoir to the high pressure pump. A pair of radial vapor ports are disposed between an inside diameter of a pump channel of the turbine pumping stage and an outside diameter of a concentric, radially inboard pump channel of the side channel pumping stage at a discharge port of the pump channel of the side channel pumping stage. Liquid fuel with entrained vapor near the inside diameter of the pump channel of the turbine pumping stage is aspirated through the radial vapor ports into the discharge port of the pump channel of the side channel pumping stage by liquid fuel flowing in the pump channel of the side channel pumping stage.

摘要： An apparatus is described for transporting particulate material. A housing includes a wall defining an inlet and a wall defining an outlet spaced downstream from the outlet. A duct is enclosed in the housing between the inlet and outlet, the duct being formed between first and second substantially opposed drive walls moveable relative to the housing from the inlet toward the outlet and at least one arcuate wall extending between the inlet and the outlet. The drive walls have a greater surface area for contacting the solid material than the arcuate walls. The drive walls rotate relative to an axis. An assembly is provided for positioning the second drive wall in the housing for rotation in a plane at an angle relative to the axis such that the distance between the first and second drive walls adjacent the inlet is greater than the distance downstream from the inlet when the drive walls are moving.

摘要： A unit for delivering fuel from a supply tank to an internal combustion engine, having a disklike impeller driven to revolve in a pump chamber, on whose circumference a number of blades are disposed, and having at least one supply conduit, disposed in the region of the impeller blades and open toward the impeller, in a chamber wall defining the pump chamber on the face end and axially adjoining the impeller, which supply conduit extends via a split ring around the pivot axis of the impeller from an inlet opening into the pump chamber to an outlet opening from it. In order to assure that sufficient fuel can be aspirated unthrottled in the presence of gas bubbles in the fuel, in particular when the fuel is hot, the supply conduit is embodied in the region of the inlet opening as larger by a factor of 2 than the usual supply conduit cross section; the cross section of the supply conduit then decreases continuously, beginning at the inlet end, forming a compression conduit.

摘要： The instant invention is a self-adjusting blade insert used for improving the efficiency of low rotating disc pumps by use of pivotal disc inserts disposed between the rotating discs of a multi-disc pump turbine style pump causing a positive displacement of fluid during the low rotating conditions or low viscosity fluid environment. The blade inserts of the instant invention include a biasing spring which allows the blade inserts to pivot outward when sufficient hydraulic pressure creates force against a lower surface of the blade inserts allowing maximum flow at higher rotations or predetermined operating conditions.

摘要： An electrically operated fuel pump for automotive vehicles which utilizes a turbine pump rotor operating in an annular pumping channel having circumferentially spaced inlet and outlet ports. The pumping channel has opposed sides with a circumferential array of radially curved grooves axially opposed to the periphery of the impeller and extending radially inwardly from the impeller vanes. The pump has a main outlet leading to the engine to be supplied with fuel. A secondary outlet leads to a fuel jet positioned to direct fuel into a venturi passage to draw fuel from a pump inlet and discharge it into a reservoir in a main fuel tank, the pump being located in the reservoir. A biased valve in the secondary outlet opens when the pump outlet pressure reaches a predetermined pressure to insure adequate fuel flow to the engine upon cold start conditions before fuel is drawn by the jet and venturi and delivered to the reservoir.

摘要： A vortex wall (14) and impeller (30) assembly for a transverse or cross flow fan (10). The wall is intended to reduce blade rate tonal noise and is formed in a number of segments (15). The segments have noses with J shaped cross sections and are arranged so that the J tail (16) of one segment points in the opposite direction from the J tail of an adjacent segment. The spanwise widths (W), segment-to-impeller clearances (c) and setting angles (.theta.) vary randomly, within specified limits, among the segments.

摘要： An aggregate for feeding fuel from a supply tank to an internal combustion engine of a motor vehicle has a fluid pump having an impeller with a plurality of vanes distributed over its periphery on its both end surfaces, elements forming a pump chamber in which the impeller is rotated and including two wall parts limiting the pump chamber in direction of a rotary axis of the impeller at both sides and a housing part limiting the pump chamber in a radial direction, each of the wall parts having an end surface facing the impeller and being provided with a substantially ring-shaped feeding passage, at least one of the feeding passages having a connection with a suction side of the flow pump and at least the other of the feeding passages has a connection with a pressure side of the flow pump. The impeller and the housing part are arranged so that a radial gap between an outer surface of the impeller and an inner surface of the housing part at least in a peripheral region of the housing part in which the connection of the one feeding passage with the suction side is provided has such a size that a suction passage is formed through which the other feeding passage is also connected with the suction side of the flow pump. For limiting the suction passage in a peripheral direction near the suction passage, peripheral regions are arranged in which the radial gap is smaller.

摘要： A unified fuel pump assembly combines a vane-type pump and a booster stage for the inlet of the vane-type pump, in a unitary structure to substantially reduce "windage" losses caused by relatively moving parts. The unified structure also includes an electric motor subassembly to provide motive power, and a liquid ring pump, which helps to process air bubbles through the fuel pump, is coupled to the electric motor rotor to further avoid "windage" losses. The vane type pump relies on the use of a central shaft capable of having a substantially uniform and relatively large diameter from end to end.

摘要： A fuel pump has a motor with a shaft extending therefrom and an impeller fitted thereon for pumping fuel from a fuel tank to an internal combustion engine. A pumping chamber, which encases the impeller, is comprised of a cover channel and a bottom channel formed in a pump cover and a pump bottom, respectively. The impeller has a plurality of radially extending vanes on an outer circumference separated by partitions of shorter radial length. The partitions are comprised of quarter-circle shaped arcuate portions extending from the outer circumference of the impeller to a straight portion having parallel sides, which preferably extend approximately 0.1 millimeters to 0.5 millimeters, to a flat top with rounded corners. Fluid active vane grooves thus formed circumferentially between the vanes and axially between the partitions which reduce fuel vortices angular acceleration within the pumping chamber thus increasing pump efficiency.
摘要翻译：燃料泵具有从其延伸的轴的马达和安装在其上的用于将燃料从燃料箱泵送到内燃机的叶轮。包围叶轮的泵送室分别由形成在泵盖和泵底部的盖通道和底部通道构成。叶轮在外周上具有多个径向延伸的叶片，该叶片由较短径向长度的隔板分开。隔板由从叶轮的外周延伸到直线部分的四分之一圆弧形的弓形部分组成，平直的边缘优选地延伸约0.1毫米至0.5毫米到具有圆角的平坦的顶部。因此，流体活动叶片槽周向地形成在叶片之间并且在分隔件之间轴向地减小燃料涡流在泵送室内的角加速度，从而提高泵效率。
