A low pressure lubrication or oiling system including: a pump; a nozzle having a circular end face and a discharge orifice having one end of the orifice being open to the circular end face with oil pumped by the pump being supplied through the orifice to a plurality of operating members which require lubrication, and a flow control valve positioned between the pump and the nozzle. The diameter of the orifice ranges from 0.3 mm to 0.8 mm with the outer diameter of the circular end face being at least two times as large as the diameter of the orifice, and the length of the orifice being at least six times as large as the diameter of the orifice so that a small amount of oil may be dropped in the form of a continuous line at a feeding rate of 3 to 20 cc / min.
