Abstract: A rotary electric machine includes an enclosure delimiting an internal space for stator and rotor units. An access hole gives access to the internal space. An internal gasket encircles the access hole adjacent a wall of the enclosure. A closing element is disposed in the internal space, movable towards and away from the wall between a closed configuration compressing the gasket to seal the access hole and an open configuration connecting the internal space with the surrounding atmosphere. An elastic device operates to move the closing element from the open to closed configurations to compress the gasket and seal the access hole. The closing element has a pressure surface facing the access hole and accessible through the access hole via a pin. Pressing the pressure surface causes the closing element to move from the closed configuration to the open configuration.

Abstract: An electric liquid pump includes a casing having a central portion, rear cover and front cover, having an inlet and an outlet for the liquid. The central portion has first and second compartments, with the second compartment in fluid communication with the front cover interior. The pump includes an impeller and an electric motor, for operating the impeller, a stator housed in the first compartment, a rotor, coaxial with the stator, housed in the second compartment and an electronic card for supplying the stator at least partly housed in the rear cover. The central portion includes a plurality of walls delimiting a plurality of gaps in fluid communication with the second compartment and the front cover interior such that the liquid circulates in the gaps. The walls at least partly face the stator such that the liquid circulating in the corresponding gap removes heat from the stator.
