Control module for a nozzle arrangement

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, comprising a gas supply line for pressurized gas and a liquid supply line for pressurized liquid, both leading to the at least one 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 at least one two-component nozzle, wherein the packing includes a cavity defined by a liquid volume limiter and, at the valve-end side, the open ends of the capillary tube pass through a sealing disc and dip into the cavity.
