<p>The lubricant metering system is for a rotary mechanism in which a rotor is supported within a housing cavity for planetary rotation and defines with the housing a plurality of working chambers which successively expand and contract as the rotor rotates. The rotary mechanism also has an inlet port means in the housing for passing gaseous fluid into the working chambers, the inlet port means and rotor being constructed and arranged to control the flow through the inlet port means to effect an opening of the inlet port means after the working chamber has commenced expansion and flow through said open inlet port means at a high velocity which may approach sonic speed through the inlet port means. The lubricant metering system is a small tube communicating at one end with a source of lubricant and disposed with the other open end communicating with the inlet port means so as to provide a droplet of lubricant to said inlet port means for entrainment by the gaseous fluid flowing through the open inlet port means.</p> |
