Beschreibung
Zusammenfassung:	A motor pump of the present invention includes a rotating shaft rotatable around an axis, a driving section including a rotor core integrally fixed to an outer circumference of the rotating shaft and a stator surrounding an outer circumference of the rotor core, a compression section which compresses a working fluid, a casing surrounding the rotating shaft, the driving section, and the compression section, a partition member radially partitioning the inside of the casing into a first space in which the stator is disposed and a second space in which the rotor core is disposed, a first connection path connecting the first space to a first portion in the compression section, and a second connection path connecting the second space to a second portion in which the pressure of the working fluid is higher than that of the first portion in the compression section.
