Abstract: An atomizer unit of a lubrication system has a chamber arrangement having a chamber arrangement interior, at least one first supply duct for supplying a first compressed-air stream into and through the chamber arrangement interior to a continuation duct, and an injection valve for injecting a coolant and/or lubricant into an injection region into the first compressed-air stream in the chamber arrangement interior. The atomizer unit has at least one second supply duct for supplying a second compressed-air stream into and through the chamber arrangement interior to the continuation duct. The atomizer unit is designed in such a manner that the second compressed-air stream combines with the first compressed-air stream and with the coolant and/or lubricant possibly injected into the first compressed-air stream, to form a transport stream for transporting the injected coolant and/or lubricant, and the transport stream is routed through the continuation duct to the machining location.

Abstract: The invention relates to an atomizer unit of a minimal quantity lubrication system (3) for cooling and/or lubricating a chip-removing machining process between a tool (5) and a workpiece (6) at a machining station, wherein the atomizer unit (2) has a chamber arrangement (8) with a chamber arrangement interior (9), at least one first supply duct (10) for supplying a first compressed air stream (11) into and through the chamber arrangement interior (9) to a continuation duct (12) and an injection valve (13) for injecting a coolant and/or lubricant (4) into an injection region (14) into the first compressed air stream (11) in the chamber arrangement interior (9).
