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 rotating assembly that is mounted to a shaft. The electric motor creates a primary torque flow path that drives rotation of the rotating assembly relative to the stator assembly. The pulley is rotatable relative to the shaft and the rotating assembly. The pulley assist mechanism includes a plurality of circumferentially spaced teeth nested with a conductive body, a rotor body fixedly mounted to the shaft, and an electromagnet that is configured to induce a magnetic field between the circumferentially spaced teeth, the rotor body, and the pulley, which creates a secondary torque flow path between the pulley and the rotor body.

A centrifugal blood pump includes: a housing; a suction inlet for introducing blood into the housing; an impeller that is rotatably disposed in the housing and imparts a centrifugal flow to the blood introduced through the suction inlet by rotation; and a discharge outlet for discharging the blood given a centrifugal flow by the impeller. The impeller is formed in a double impeller structure including double vanes arranged vertically.

A liquid pumping device (1) for beverage dispenser comprising:-a housing (2) with a liquid inlet (3) and a liquid outlet (4);- a gear pump (5) positioned in the housing with the liquid inlet communicating with the gear pump; wherein a flowmeter (6) is fluidly positioned in the housing (2) preferably between the gear pump (5) and the liquid outlet (4).

A double suction impeller is disclosed. In at least one embodiment, the impeller is configured for centrifugal pumps and hydraulic power recovery turbines. The impeller's flow-path arrangement comprises inter-blade channels, intersecting each other at the impeller's outer diameter and defining a variable cross section shape, so that the equivalent number of blades is at least doubled with respect to a conventional configuration obtained by the coupling of two single suction impellers and an improved control over the velocity of the flow within the inter-blade channels is achieved.

The jacket is provided monolithically.

A laundry treating apparatus includes a duct system including an air discharge duct for discharging air inside the drum to an outside of the drum, an air supply duct for supplying air to the drum, and a connection duct for connecting the air discharge duct and the air supply duct to each other. The apparatus also includes a heat-absorber disposed inside the connection duct to remove moisture from air, and a heat-emitter disposed inside the connection duct to heat air passing through the heat-absorber. The apparatus further includes a water ejector disposed in the duct system and defining a water flow path for supplying water to the heat-absorber to remove foreign substances remaining on the heat-absorber.

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 double suction impeller is disclosed. In at least one embodiment, the impeller is configured for centrifugal pumps and hydraulic power recovery turbines. The impeller's flow-path arrangement comprises inter-blade channels, intersecting each other at the impeller's outer diameter and defining a variable cross section shape, so that the equivalent number of blades is at least doubled with respect to a conventional configuration obtained by the coupling of two single suction impellers and an improved control over the velocity of the flow within the inter-blade channels is achieved.

A pump (2) system includes a pump, a sensor (22; 28) arranged in or at a flow path (14), and a concentration measurement device measuring a concentration in liquid inside the flow path (14). The concentration measurement device includes the sensor (22; 28), as a concentration sensor, connected to an evaluation device (26) for evaluating readings of the sensor (22; 28). The evaluation device (26) is connected to a further signal source (20; 24), providing at least one further parameter, and is configured to carry out an evaluation of the reading of the sensor (22; 28), taking into account the further parameter provided by the further signal source (20, 24) to output the concentration in the liquid. A solar heating system includes the pump system.
