PURPOSE: An oil feed spray apparatus for pneumatic machines and a lubricating and rust preventing method for pneumatic machines using the same are provided to supply an optimum amount of oil according to the operational environment of the pneumatic machines, using a single oil feed apparatus and a simple flow sensor. CONSTITUTION: An oil feed spray apparatus for pneumatic machines comprises a main pipe, a solenoid valve which converts the air flow direction of the main pipe, an oil supply pipe which is branched from the solenoid valve and joined at a second spot of the main pipe, an oil feed spray(30) which is arranged on the path of the oil supply pipe, a pressure reduction valve which is branched from the oil supply pipe and arranged between the oil feed spray and the second spot, and a flow sensor(40) which senses the flow rate of the air passing through the second spot. |
