The technical solution used in the present invention is: comprise radial fuel inlet fitting, horizontal spray bar, upper oil baffle and lower oil baffle, the two ends of described horizontal spray bar are separately installed with shutoff, described radial fuel inlet fitting is connected with horizontal spray bar, the tube wall of horizontal spray bar is provided with multiple nozzle opening, the inner space of nozzle opening and horizontal spray bar; Described upper oil baffle and lower oil baffle are arranged on horizontal spray bar, and upper oil baffle is arranged near nozzle opening.
Above-mentioned in the modular fuel injector device of Tilting Pad bearing, described horizontal spray bar is pipe, and described multiple nozzle openings are positioned on the same bus of horizontal spray bar, and the spacing between two adjacent nozzle openings is identical.
Above-mentioned in the modular fuel injector device of Tilting Pad bearing, described radial fuel inlet fitting is connected with in the middle part of horizontal spray bar, the radial axis of fuel inlet fitting and the axes normal of horizontal spray bar, the angle of the axis of nozzle opening and the axis of radial fuel inlet fitting is obtuse angle.
Above-mentioned in the modular fuel injector device of Tilting Pad bearing, described upper oil baffle and lower oil baffle are arranged on two bus places crossing with the center line of radial fuel inlet fitting on horizontal spray bar respectively.
Above-mentioned in the modular fuel injector device of Tilting Pad bearing, described upper oil baffle is the thin plate of cross section V-type in obtuse angle.
Above-mentioned in the modular fuel injector device of Tilting Pad bearing, the thin plate of described lower oil baffle to be cross section be L-type.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention can according to the size of Tilting Pad bearing, rationally adjust fuel delivery and the lube range of whole bearing efficiently, the present invention is provided with oil baffle and lower oil baffle on horizontal spray bar, the deep fat of a upper tile fragment is blocked by upper oil baffle and lower oil baffle after tile fragment end face oil film wedge flows out, directly flow out from end face, next tile fragment can not be flowed into and lubricate; The cold oil of the nozzle opening ejection of horizontal spray bar is imported next tile fragment by upper oil baffle, the cold and hot oil content of different tile fragment can well be opened like this, the lubrication of each tile fragment is independently, reduces the temperature of Tilting Pad bearing, improves the reliability of Tilting Pad bearing.The present invention also has structure advantage simple, easy for installation.

Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As in Figure 2-4, the present invention includes radial fuel inlet fitting 5, horizontal spray bar 6, upper oil baffle 7 and lower oil baffle 4, the two ends of described horizontal spray bar 6 are separately installed with shutoff 3, described radial fuel inlet fitting 5 is connected with the middle part of horizontal spray bar 6, the axis of radial fuel inlet fitting 5 and the axes normal of horizontal spray bar 6.Horizontal spray bar 6 is pipe, and the tube wall of horizontal spray bar 6 is provided with multiple nozzle opening 8, can well control oil inlet quantity by the quantity adjusting nozzle opening 8; Multiple nozzle opening 8 is located on same bus, and the spacing between two adjacent nozzle openings 8 is identical.The angle of the axis of nozzle opening 8 and the axis of radial fuel inlet fitting 6 is obtuse angle, the inner space of nozzle opening 8 and horizontal spray bar 6.Described upper oil baffle 7 and lower oil baffle 4 are arranged on horizontal spray bar 6, and be arranged on the two bus places crossing with the center line of radial fuel inlet fitting 5 respectively, upper oil baffle 7 is arranged near nozzle opening 8.As shown in Figure 5, centered by described radial fuel inlet fitting 5, place is provided with the cylindrical of through hole, also can be that center is provided with the prismatic of through hole.As shown in Figure 6,7, centered by described horizontal spray bar 6, place is provided with the cylindrical of circular port, and also can be that center is provided with the prismatic of circular port, the two ends of circular port be provided with internal thread, for installing shutoff 3 or connecting other jet pipes.As shown in Figure 8, described upper oil baffle 7 is the thin plate of cross section V-type in obtuse angle.As shown in Figure 9, described lower oil baffle 4 for cross section be the thin plate of L-type.
