Description: |
| Claim:
A unit for entraining an essentially non-volatile oil finely divided droplet form in an air carrier, comprising: a body having a top and a bottom and an air filet passage extending from one side, an oil supply bowl secured to said bottom, an oil delivery tube secured to said body and within said bowl, entrainment means communicating with said air inlet passage and said oil delivery tube for entraining oil in droplet form in pressurized air from said inlet passage and for directing the flow droplet carrying air upwardly, a barrier member secured to said top and having a concave surface facing said entrainment means for reducing droplet size and for removing larger droplets by centrifugal action and by adhesion to said surface, said body having a through passage for flow of droplet carrying air from said surface to said oil bowl above the level of oil therein, and an outlet passage for flow of droplet-carrying air out of said bowl, and said body having downwardly projecting barriers around said through passage for further removal of larger droplets from the air, a valve member rotatably journaled in said body and extending from said top at one fie of said barrier member to a point between said de-rery tube and said entrainment means for controlling flow of oil, and a ball check valve between said entrainment means and said delivery tube for preventing back flow of oil. |
