Abstract
An electric compressor includes a housing and a compression device. The housing defines an intake volume and a discharge volume. The compression device is a rotary-type compression device configured to compress refrigerant. The compression device includes a piston device including a cylinder and a rolling piston. The cylinder is eccentrically coupled to a drive shaft. The rolling piston has an outer surface in contact with an inner surface of a compression chamber. The rolling piston rotates about the cylinder as the drive shaft and the piston device are rotated by a motor. A vane moveably coupled to the housing and having an end adjacent the compression chamber is biased such that the end of the vane is in contact with the rolling piston as the piston device is rotated by the drive shaft.
