Abstract:
1. A minimal lubrication device comprising: a storage reservoir for a lubricant liquid, a single high pressure pump module comprising a single high pressure pump for increasing pressure of said lubricant liquid to discharge pressurized liquid lubricant from said single high pressure pump module, said high pressure pump of said high pressure pump module having a lubricant liquid suction port for receiving said lubricant liquid from said reservoir, said pump having a lubricant liquid delivery port, at least one modular element for mixing a compressed air flow with the pressurized lubricant liquid from the pump module, a mixer element, wherein the single high pressure pump module is fixable to at least one said modular element and each modular element presents a lubricant liquid passage, each lubricant liquid passage being a through passage opening into respective opposed openings of surfaces of the at least one modular element such that said single pump lubricant liquid delivery port is connected to the lubricant liquid passage of the at least one modular element, wherein the at least one modular element comprises a flow regulator fed by the pressurized lubricant liquid originating from the single pump, wherein the flow regulator is a needle flow regulator, and wherein said modular element is connected to the mixer element for feeding the compressed air flow and the lubricant liquid to the mixer element to mix the compressed air flow with said lubricant.
