An electric motor and inverter assembly () used in an electric vehicle or a hybrid electric vehicle to drive the vehicle's wheels to rotate is disclosed. The electric motor and inverter assembly comprises: an electric motor (), which includes a housing including a main shell (), an end cover () and a connecting cover (), wherein a cooling passage is formed in a wall of the housing such that coolant is able to flow in the cooling passage, and an end cover () and a connecting cover () are respectively connected to opposite ends of the main shell; and an inverter, which includes a housing () in which a power element and/or an electrical device is received, wherein the housing of the inverter contacts the connecting cover such that an interface is defined between the connecting cover and the housing of the inverter, and the coolant flowing through the cooling passage is able to contact the interface.

Electric motor and inverter assembly

An electric drive system () used in an electric vehicle or a hybrid electric vehicle to drive the vehicle's wheels to rotate. The electric drive system () includes an electric motor (). The electric motor () includes a housing in which a stator and a rotor are received. A transmission device () is operatively coupled to the electric motor (); and an output shaft () is operatively coupled to the transmission device (). The output shaft () extends from the transmission device () and is substantially parallel to the rotor's axis of the electric motor (). The electric drive system () also includes an inverter () secured over the housing of the electric motor () such that the inverter is located between the output shaft () and the housing of the electric motor ().

Electric drive system

Proposed is a fuel injector for injecting fuel into a combustion chamber of an internal combustion engine. The fuel injector has a housing in which are arranged an injection valve element with a nozzle needle, a pressure boosting device, and a first control valve, and a second control valve. The first control valve controls a control space of the nozzle needle and the second control valve controls a differential pressure space of the pressure boosting device. A first return flow connection is provided for discharging the control quantity of the control space of the nozzle needle, and a second return flow connection is provided for discharging the control quantity of the pressure boosting device. The two return flow connections are arranged on different housing parts of the housing.
