System for lubricating and cooling a mechanical assembly
First Claim
1. A system for lubricating and cooling a mechanical assembly, said system comprising:
- a main lubricating and cooling device circulating a stream of lubricating and cooling liquid through said mechanical assembly at a relatively high pressure; and
an auxiliary backup lubricating and cooling device set in operation automatically or manually in response to a condition that said main device becomes defective, said backup device comprising;
a first path comprising at least one reservoir of lubricating and cooling liquid that operates to feed said lubricating and cooling liquid provided under pressure;
a second path comprising at least one source of pressurized gas that operates to output pressurized gas from said source;
a feed mechanism that receives said lubricating and cooling liquid provided by said first path and said pressurized gas provided by said second path and outputs said pressurized gas and liquid;
at least a first spray nozzle and a second spray nozzle that each receive said pressurized gas and liquid output from said feed mechanism, for spraying said pressurized gas and liquid onto said mechanical assembly; and
said first path further comprising a pressure and flow limiter arranged between said reservoir and said first and second spray nozzles, and wherein;
said first and second spray nozzles are fed with the lubricating and cooling liquid from said reservoir at a pressure at most equal to 2 bar (2·
105 pascal).

Abstract
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).
