  • Patent number: 9819247
    Abstract: In an electrical machine for the hybrid drive of a vehicle, an annular cooling jacket extends between a housing and a casing. The cooling jacket is connected to a coolant inlet and a coolant outlet so that coolant is axially introduced into the cooling jacket. The coolant inlet and the coolant outlet are situated next to each other in the circumferential direction of the housing and are hydraulically connected to a deflection section by way of coolant ducts. Coolant introduced into the cooling jacket flows in two partial flows in opposite directions, to the deflection section through coolant ducts forming an intake. The coolant is deflected back to the coolant outlet through a coolant duct forming a return. The coolant flows through the coolant duct of the return and the axially adjacent coolant duct of the intake in opposite directions.
