Abstract

See full text

A lubricating and cooling system for a mechanical assembly includes a first path having a reservoir of lubricating and cooling liquid and a second path having a source of pressurized gas. A feed mechanism receives the lubricating and cooling liquid from the first path and the pressurized gas from the second path and outputs the pressurized gas and liquid. First and second spray nozzles spray the pressurized gas and liquid onto the mechanical assembly. The first path has a pressure and flow limiter arranged between the reservoir and the first and second spray nozzles so that the first and second spray nozzles are fed with the lubricating and cooling liquid at a pressure no greater than 2 bar (2×105 Pascal).
