A compressor assembly including a compression mechanism, a rotating crankshaft operably coupled to the compression mechanism, the crankshaft provided with a longitudinally-extending oil conveyance passageway, the oil conveyance passageway in fluid communication with relatively moving interfacing bearing surfaces of the compression mechanism, and an oil pump assembly. The oil pump assembly includes an oil pump body having an interior surface and being rotatable relative to the crankshaft, a vane disposed within the pump body and rotating with the crankshaft, the vane having at least one end in sliding engagement with the interior surface of the oil pump body, and a port plate disposed within the pump body and having rotatably opposite first and second positions. The vane is in sliding engagement with an adjacent surface of the port plate, and the port plate is provided with an inlet and an outlet. The pump body receives oil from a source of oil, the oil received in the pump body directed by the vane into the port plate inlet, the port plate outlet in fluid communication with the oil conveyance passageway, the oil directed into the port plate inlet urged toward the port plate outlet in response to relative movement between the vane and the port plate, whereby oil is pumped from the source of oil through the oil conveyance passageway.
