摘要： An improvement in a fuel pump for an internal combustion engine in which the fuel pump comprises an electric motor over which fuel is pumped to cool the motor, and a pump mechanism, constituted as a side-channel pump driven by the electric motor, pumps the fuel. The pump mechanism has a pump impeller provided with two opposite radial surfaces each provided with an annular ring of blades respectively cooperating with side channels provided in a pump wall to constitute first and second pump stages. A connecting channel connects an inlet region of the side channel of the second pump stage with a discharge region of the side channel of the first pump stage in an arrangement to substantially eliminate torsional moments acting on the impeller during a fuel pumping operation. A first flat region is formed on the radial surface of the pump impeller in the first pump stage and a second flat region is formed on the radial surface of the pump impeller in the second pump stage. The pressure of the fluid discharged from the second pump stage is applied to the first flat region, and the pressure of the fluid discharged from the first pump stage is applied to the second flat region so that a net axial force applied to the first and second flat regions of the pump impeller by the respective pressures of the fluid in the first and second stages substantially counterbalances a force produced on the pump impeller by the pressure of the discharged fluid acting in the direction of the first pump stage.

摘要： A fuel supply system for an internal combustion engine in which an electrical fuel pump pumps fuel from a fuel tank to a fuel distributor and a pressure switch is connected to respond to the pressure of the fuel. The pressure switch is electrically connected to connect and disconnect electrical power supply to the fuel pump as a function of lower and upper threshold values of pressure of the pumped fuel. The pressure switch contain a storage chamber which stores fuel when the fuel pump is operative and when the pump is disconnected, the storage chamber supplies the stored fuel to the full distributor with no back flow to the fuel tank. A pressure reducing regulator is located between the pressure switch and the fuel distributor to reduce the pressure of the fuel supplied to the distributor to a value lower than the pressure of the fuel at the pressure switch.

摘要： A fuel feed device having a first pump assembled with an electric motor in a sheet-metal shell to form a self-contained unit. The drive shaft of the motor projects from the unit and is drivingly connected to an impeller of a second pump whose housing surrounds the impeller. The housing of the second pump surrounds part of the self-contained unit and a sleeve is pushed over the self-contained unit with clearance therebetween and is connected at its lower end to the second pump housing and forms a seal with the self-contained unit by a holding ring and an elastic membrane. The device is easily adapted to casings of the first pump of any form and shape and to requirements, such as changes in filter size, mounting in the fuel tank, and for different types of second pumps.

摘要： A vane pump having a plurality of working chambers each of whose volume changes from a minimum to a maximum value and back again during one revolution, and wherein intake and delivery ports open axially into the working cells and are formed with cross sections adapted for fluid conveyance without internal compression. Such compression is achieved by a valve plate which forms a non-return and is formed with a resilient tongue valve which, commencing from the starting end of the delivery port controls, upon proper pump operation, about two-thirds of the cross section of the mouth of the delivery port.

摘要： An electric pump for a liquid has a rotor surrounded by a stator which is disposed in the flow path of the liquid, the rotor being disposed in a rotor compartment, which is sealed from the flow path of the liquid and is predominantly filled with a mixture of air and vaporized liquid. The rotor compartment is in communication with the ambient atmosphere through a vent orifice. A vent system in the form of a labyrinth seal and a liquid-tight, gas-permeable membrane is interposed between the vent orifice and the ambient atmosphere. The rotor bearings are lubricated in one embodiment by leakage liquid and its vaporized product within the rotor compartment. In another embodiment the rotor bearings are disposed in the liquid flow path outside seals between the rotor and the rotor compartment.
