Oil transportation conduit (13) from pipe (7) end section；In two level flow-guiding channel (23), a circle is provided with around the upper fluid course
The poly- oily channel (26) of annular, the bottom of the poly- oily channel is blind slot, is not connected between two-stage supercharging runner (24)；It surrounds
The top of the poly- oily channel is opened there are one the two-stage positioning slot (25) of annular, and the two-stage positioning slot is used for connecting coarse separation
Manage the tail end of (7)；
On the tube wall of two level flow-guiding channel (23), several points of oilholes (29) are provided in the interval of two helixes, described point
Oilhole begins to extend radially through into poly- oily channel (26) from the tube wall.
