Abstract: An electric machine and differential gear assembly for providing power to a vehicle is disposed within a housing structure. The electric machine has a stator portion, and a rotor portion disposed radially inward of the stator portion and spaced therefrom by an air gap. The differential gear assembly includes a rotatable tubular housing that contains a first bevel output gear, a second bevel output gear, and two idler bevel gears. The first bevel output gear is rigidly connected to one end of a first axle, and the second bevel output gear is rigidly connected to one end of a second axle. The end portion of the first axle is supported by the housing structure via a set of bearings. The idler bevel gears are rotatably mounted on respective shafts that are each connected to the housing. The housing is rotatably supported by the housing structure via a set of bearings.

Abstract: An ice bank chiller comprises a reservoir, a vertically extending cooling coil adjacent to a side wall of the reservoir, and an agitation pump for agitating water contained in the reservoir, the agitation pump being arranged to cause substantial circulation of the reservoir water adjacent to ice on both the upper and lower regions of the cooling coil in order to promote an even thickness of ice on the cooling coil. The agitation pump comprises an impeller rotatable within a pump housing, the housing being provided with a plurality of circumferentially spaced-apart pump outlets, through which streams of water are directed towards the ice on the upper region of the cooling coil (2).
