Abstract
The invention is a low volume lubricant delivery system for delivering low volumes of lubricant, entrained by gas, to workpieces and comprises essentially: a plurality of electrical conductors; a plurality of lubricant passages and a plurality of gas passages, preferably pipes; a compressor for supplying gas under pressure; a gas inlet; a gas outlet; gas flow control valves, one of which is a solenoid valve; a constant pressure pump; a lubricant entrainment structure, preferably a nozzle; a lubricant outlet; lubricant flow control valves, of which one is a solenoid valve; a lubricant supply and a timer. The lubricant supply being connected to the constant pressure pump by at least one lubricant pipe; the constant pressure pump means being connected to the lubricant flow control valves by at least one lubricant pipe and to the gas flow control valves by at least one gas pipe; the lubricant flow control valves being connected to the lubricant outlet by at least one lubricant pipe; the gas flow control device being connected to and between the gas inlet and the gas outlet by a gas passage; the gas inlet being connected by a gas passage to the gas supply; the timer being connected to the lubricant flow control valves by the power conductors; the timer generally controlling the operation of the lubricant flow control device so that the amount of lubricant delivered to the lubricant outlet is controlled; the lubricant entrainment nozzle comprising at least both the coolent outlet and the gas outlet; whereby the gas from the gas supply is delivered through the low volume lubricant delivery system to the gas outlet in the gas entrainment device and the lubricant from the lubricant supply is delivered through the low volume lubricant delivery system to the lubricant outlet in the gas entrainment device where the gas and the lubricant are discharged and the gas entrains the lubricant and delivers the lubricant to the workpiece.
