Abstract

An electric pump (2) draws and discharges fluid. When the fluid receives heat from the pump (2), the fluid has a saturation vapor pressure that can surpass the pressure of fluid that is drawn into the pump (2) and is lower than the pressure of fluid discharged from the pump (2). The pump (2) includes an electric motor; a pump section that is driven by the electric motor (M) to draw, pressurize, and discharge the fluid; and a housing (6) for accommodating the pump section. The housing (6) defines a motor chamber (156) that accommodates the electric motor (M). The pressure in the motor chamber (152) is equal to the pressure of fluid that is discharged from the pump section. Therefore, the pump (2) prevents fluid in the motor chamber (152) from vaporizing.
