1. A scroll-type electric compressor configured to compress a refrigerant, comprising:
a housing defining an intake volume and a discharge volume;
a refrigerant inlet port coupled to the housing and configured to introduce the refrigerant to the intake volume;
a refrigerant outlet port coupled to the housing and configured to allow compressed refrigerant to exit the scroll-type electric compressor from the discharge volume;
an inverter module mounted inside the housing and adapted to convert direct current electrical power to alternating current electrical power;
a motor mounted inside the housing;
a drive shaft coupled to the motor; and,
a compression device for receiving the refrigerant from the intake volume and compressing the refrigerant as the drive shaft is rotated by the motor, the compression device including:
a fixed scroll located within, and being fixed relative to, the housing, and
an orbiting scroll coupled to the drive shaft, the orbiting scroll and the fixed scroll forming compression chambers for receiving the refrigerant from the intake volume and compressing the refrigerant as the drive shaft is rotated about a central axis, the orbiting scroll having a first side and a second and an oil aperture through the orbiting scroll from the first side to the second side,
a swing-link mechanism coupled to the drive shaft,
a ball bearing positioned between, and adjacent to each of the orbiting scroll and the swing-link mechanism, the drive shaft, orbiting scroll, and swing-link mechanism being arranged to cause the orbiting scroll to orbit the central axis in an eccentric orbit, and,
a pin having an oil orifice and press fit within the oil aperture of the orbiting scroll, wherein the oil orifice is configured to allow oil to pass through the orbiting scroll to the ball bearing.
