An electrically and mechanically driven automotive accessory including a housing, an electric motor, a pulley, and a pulley assist mechanism. The electric motor comprises a stator assembly that is mounted to the housing and a rotor assembly that is mounted to a shaft. The electric motor creates a primary torque flow path that drives rotation of the rotor assembly relative to the stator assembly. The pulley is rotatable relative to the shaft and the rotor assembly. The pulley assist mechanism includes a plurality of claw-pole structures that are arranged circumferentially about the rotor assembly and an electromagnet that is configured to induce a magnetic field between the claw-pole structures and the pulley, which creates a secondary torque flow path between the pulley and the rotor assembly.

A pump module includes a main body, a first pump and a second pump. The main body includes a fluid channel, a first mounting hole and a second mounting hole.

An impeller pump has a pump chamber with an inlet and an outlet, and an impeller in the pump chamber. An auxiliary outlet out of the pump chamber together with an auxiliary outlet flap is provided, the auxiliary outlet flap having a closed position and at least one open position and being rotatable or movable between the positions. In the closed position, the auxiliary outlet flap closes off the auxiliary outlet and, in each of the open positions, the auxiliary outlet flap at least partially opens the auxiliary outlet. The auxiliary outlet flap has an actuator and is subjected to force loading by the actuator, such that the auxiliary outlet flap is moved automatically from the closed position into one of the open positions if the auxiliary outlet flap is free from fluid flow in a direction of rotation of the impeller.

The present invention relates to a vehicular heating device comprising: a vehicular engine cooling unit for connecting an engine, a water pump, and a radiator on a first cooling water circulating line to cool the engine; and a vehicular indoor space heating unit for connecting the engine, the water pump, and a heater core on a second cooling water circulating line to heat an indoor space of the vehicle, wherein the vehicular heating device comprises a heating means mounted on the second cooling water circulating line to heat cooling water supplied to the heater core.

An axial flow pump comprises a housing having a bore, a cylindrical permanent magnet within the housing bore, and at least one impeller inside the permanent magnet and adapted to cause fluid to flow within the cylindrical permanent magnet. The permanent magnet is configured to rotate in the bore around its longitudinal axis. A motor lamination stack surrounds the cylindrical permanent magnet. The motor lamination stack is formed substantially as a cuboid, extending in a width and height direction perpendicular to the axis of rotation of the cylindrical permanent magnet. The diameter of the bore is at least 80% of the dimension of the cuboid in the height direction. A coil of the motor lamination is configured to be energized and to create a rotating magnetic field in the lamination stack to rotate the cylindrical permanent magnet around its longitudinal axis. The coil is disposed to one or both sides of the pump.

A pump system or device is provided for removing water from a pool cover or sump, featuring a controller configured to respond to a signal containing information about the ambient temperature in relation to a pump and to provide a controller signal containing information to control the operation of the pump based at least partly on the ambient temperature. The pumping system or device me be configured to include some combination of the following: temperature sensing, including a Thermistor, to change control logic at temperatures below a specific level (e.g. below 35 degrees F.); the initiation of impeller cycling at low operating temperatures to avoid ice formation in the impeller cavity and/or hose, but not for level sensing; the use of temperature feedback to turn off pump at low temperatures that may result in damage to the system; the addition of control logic to ignore torque increases due to contamination or flow-back Inclusion of soft-start of motor to reduce stress on impeller/motor; the option to connect Garden-style hose with an integral heating element to avoid freezing; a heating element to receive power from the pump via, e.g., a plug connector, where power to the heating element is supplied only when the temperature device is activated at some specified setting; the addition of a temperature sensor to render the pump inoperative if the temperature should fall below a set point (freezing); and/or the use of a field effect level sensor, such that the temperature sensing is substantially independent of the level sensing device.
