It is connected together with lower housing 3, and a string of gas chamber 11 is surrounded jointly with lower housing 3；It is fixedly installed in the chamber 11 of collaborating
There are right baffle-plate 20 and right shell body 21, the right baffle-plate 20 and right shell body 21 are L-shaped, and the right baffle-plate 20 and right shell body 21 are with logical
The vertical line for crossing 10 center of circle of entrance of collaborating is symmetry axis mirror symmetry, is offered on the lower housing 2 with air inlet pipeline 30 one by one
Corresponding four channels of collaborating, the channel of the collaborating chamber 11 that will collaborate connect one by one with the inner cavity of each air inlet pipeline 30；It is described
Right baffle-plate 20 and right shell body 21 are so that the oil gas entered by entrance 10 of collaborating is required for the flow path by equal length to enter each string
At the air inlet of gas channel.
Preferably, the channel of collaborating be followed successively by from left to right first collaborate channel, second collaborate channel, third collaborate it is logical
Road and the 4th is collaborated channel, and described first collaborates channel and the second channel of collaborating is located at 10 left side of entrance of collaborating, the third string
Gas channel and the 4th channel of collaborating are located at the right side of entrance 10 of collaborating, and the right baffle-plate 20 is located at the second the second air inlet for collaborating channel
The right side of mouthful b1, the right shell body 21 be located at third collaborate channel third air inlet c1 left side, described first collaborates channel
The first air inlet a1 and second collaborate channel the second air inlet b1 to 20 transverse arm left-end point e of right baffle-plate vertical range phase
Deng, the third collaborate channel third air inlet c1 and the 4th collaborate channel the 4th air inlet d1 to 21 transverse arm of the right shell body right side
The vertical range of end f is equal, and the second air inlet b1 and third air inlet c1 are to pass through the vertical of 10 center of circle of entrance of collaborating
Line is symmetrical arranged for symmetry axis, and the first air inlet a1 and the 4th air inlet d1 are to pass through the vertical line in 10 center of circle of entrance of collaborating
It is symmetrical arranged for symmetry axis；The right baffle-plate 20 and the leading flank of right shell body 21 with 1 Joint of cover board of collaborating, trailing flank with
