Abstract: A control module for a nozzle arrangement, including at least one two-component nozzle for spraying a gas/liquid mixture on the zones of action between a tool and a workpiece is characterized by a gas supply line for pressurized air and a liquid supply line for pressurized liquid, both leading to the two-component nozzle, a liquid check valve in the liquid supply line, a control device to be actuated by the pressurized gas for opening or closing of the liquid check valve, a packing disposed downstream of the liquid check valve, a branch line in the form of a capillary tube extending from the packing to the or each two-component nozzle.

Abstract: An apparatus for generating and spraying an aerosol which contains liquid particles in a gas stream and for pointedly supplying the aerosol to a lubricating location, comprises (a) a vessel containing a supply of liquid and a pressure space above the level of the liquid supply, (b) an atomizer disposed in the pressure space above the level of the liquid supply and comprising: (i) a spraying device for spraying the aerosol, (ii) a liquid feed line connected at one end to the liquid supply and its other end to the spraying device and including a pump for feeding the liquid, (iii) a gas feed line connected at one end to a pressure gas source and at its other end to the spraying device, (iv) at least one apertured wall disposed in the way of the trajectories of the spray jets from the spraying device and having holes for passing liquid particles of a predetermined size while separating greater liquid particles at the apertured wall, and (c) an aerosol line which connects the pressure space with a machining
