Abstract: A compressor may include a compression mechanism and an oil pump. The compression mechanism is configured to compress a working fluid. The oil pump may be defined by a driveshaft and a bearing. The driveshaft is drivingly connected to the compression mechanism and includes a lubricant passage. The bearing receives a portion of the driveshaft and includes a bearing surface that rotatably supports the driveshaft. The bearing includes a pump cavity surface that is spaced apart from the driveshaft and cooperates with a diametrical surface of the driveshaft to define a pump cavity that extends around the diametrical surface of the driveshaft. The bearing includes an inlet passage and an outlet passage. The inlet passage receives oil from an oil sump and provides oil to the pump cavity. The outlet passage receives oil from the pump cavity and provides oil to the lubricant passage of the driveshaft.
