Minimum quantity lubricating device for lubricating and cooling lubricating place, has mouth, which is tapered at opening and projects with tapering from housing, where opening outputs mixed stream of fluid lubricant and gas to place

摘要

The device has a nozzle head with a nozzle core (4), and a mixing chamber formed in the nozzle core. A fluid lubricant, such as oil, and gas, under pressure are supplied to the mixing chamber, and a nozzle mouth (8) has a nozzle opening (10) for outputting a mixed stream of the fluid lubricant and the gas to a lubricating place. A nozzle housing (2) has a casing channel for enclosing the mixed stream coming from the nozzle mouth with gas casing flow. The nozzle mouth is tapered at the nozzle opening and projects with its tapering (12) from the nozzle housing.
