An illustrative embodiment of the present disclosure includes a pump having a rotor and a plurality of vanes. The rotor is attached to a motor that rotates it in first and second directions and is located in a cavity. The plurality of vanes are each pivotally coupled to the rotor so as the rotor rotates, the vanes selectively push fluid from an inlet port out through an outlet port. The plurality of vanes each have an end selected from the group consisting of a lobe, no lobe, and a rod located in the lobe. Each of the plurality of vanes also includes a pivot pin configured to fit in a corresponding receptacle located in the rotor so that each of the plurality of vanes is pivotable with respect to the rotor inside the cavity.

An electric oil pump includes a motor including a shaft, a pump driven with the shaft therebetween, and an inverter fixed to a rear side of the motor. The motor includes a motor housing. The inverter includes an inverter housing including a circuit board accommodation portion. The inverter housing includes bus bars that connect coil ends inside the circuit board accommodation portion and extending from the motor and a circuit board to each other. The motor housing includes a bottomed cylindrical shape including a bottom portion on the inverter side. The inverter housing includes a fixed portion that is fixed to the bottom portion.
