    • A fuel supply pump is proposed where the pumping system comprises two individual pumping stages connected in seriatim and are both driven by the motor armature of an electromotor located in a common housing, and further where the drive of the pumping stage adjacent to the electromotor is accomplished by means of a contactless coupling assembly including permanent magnets fixed in the hub areas of the rotating parts of the adjacently disposed pumping stages. In a further preferred embodiment of the invention the permanent magnets are operatively associated by being in radial alignment but not in contact with each other and are separated in a pressure-tight manner by means of a rigid flange-like element inside the housing of the fuel supply assembly.

    • A securing apparatus is proposed for electric fuel pumps intended for direct in-tank installation, which enables satisfactory removal of fuel vapor from the suction area of the pump, but prevents the transmission of vibration onto the fuel spinner fixedly mounted in the tank. This is accomplished in that the elastic properties of one or more rubber elements, directly connected in the form of sleeves to the pump, are maintained even with the effects of aging, since the rubber elements are primarily stressed only by shear or bending forces. The pump is inserted, with the mounted rubber element, into a corresponding device in the fuel spinner and, so far as this is necessary, secured with clamping elements. The rubber elements fulfill the functions of holding the pump, sealing the pump suction chamber from the tank, damping noise, and removing vapor in the tank.
    • 提出了用于直接在罐内安装的电动燃料泵的固定装置,其能够从泵的吸入区域中令人满意地去除燃料蒸汽,但是防止振动传递到固定地安装在罐中的燃料旋转器上。 这是由于橡胶元件主要仅通过剪切力或弯曲力主要受到压力,所以即使由于老化的影响也能保持直接连接到泵的形式的泵的一个或多个橡胶元件的弹性特性。 将泵与安装的橡胶元件一起插入燃料旋转器中的相应装置中,并且只要这是必要的,用夹紧元件固定。 橡胶元件具有保持泵的功能,将泵吸入室从油箱中密封,消除噪音,并去除油箱中的蒸气。

    • A fluid supply pump such as a roller cell pump which includes a multiplicity of individual pumping bodies or rollers held in the grooves of a driven rotor in contact with an eccentrically disposed roller path which, in a certain angular range around the narrowest and widest gap, it is, at each location, virtually identical with a concentric circular path which is drawn around the rotor center point, the path preferably formed by two ellipse halves, for the elliptic shape can be virtually exactly approximated around the apex points of the ellipse by means of its primary circles of curvature to thereby improve the dynamic sequence of operations, for example to increase the sealing effect of the radial gap and to adapt the expansion and compression phases to the opening and closing conditions of the intake and pressure grooves.

The preferred embodiment comprises a pump of the lateral channel type having an impeller made integral with the motor armature; a tubular central housing portion which encloses the permanent magnets of the electric motor; and flange-like housing terminals on both sides of the central housing portion. The exteriors of the housing terminals are provided with pressure and suction nozzles and the interiors are provided with the stationary part of the pump and the commutator guides for the collector.

    • A method for the ventilation of fuel supply pumps as well as a new type of fuel supply pump are proposed which, particularly in pumps having two pumping stages coupled in series within the housing, serve to secure the ventilation of the first pumping stage. Preferably the first pumping stage is embodied as a lateral channel pump which has a forward anterior base plate. The ventilation bore is arranged axially at first in the base plate and in association with the lateral channel and is preferably formed during manufacture in one piece with the base plate; a reduction of the overly-large diameter of the ventilation bore is effected by the insertion of a reduction part to achieve the flow cross section required for ventilation. The ventilation to the outside of the lateral channel stage takes place via an external connection nozzle on the pump housing, which is secured thereon either axially or radially and can be embodied in one piece therewith as necessary. The connection of the ventilation bore of the lateral channel having a reduced cross section with the housing connection nozzle can be made by an elastic medially disposed member.
