Electric compressor

Abstract

An electric compressor includes a rotary shaft and a housing having a motor chamber and a suction passage. In an axial view of the rotary shaft, a second imaginary line intersects an inner peripheral surface of the housing at a first intersection point. A third imaginary line intersects the inner peripheral surface of the housing at a second intersection point. A fourth imaginary line passes through the first and second intersection points located below an axis of the rotary shaft in a vertical direction. A part of the motor chamber below the fourth imaginary line in the vertical direction and surrounded by the inner peripheral surface of the housing and the fourth imaginary line serves as a reservoir. The reservoir stores a refrigerant liquified in the motor chamber while restricting the refrigerant liquified from being introduced into a compression chamber from the motor chamber through the suction passage.
