Embodiment
The present invention is as shown in Figure 1, comprises cylindrical shell 1, orifice plug 2, throttle bar 3, fuel inlet fitting 4 and delivery connection 5;
Said cylindrical shell 1 middle part is provided with the step hole 10 that a circle protrudes in circle in the cylindrical shell 1, is respectively equipped with oil-feed direction internal thread segment and fuel-displaced direction internal thread segment on the circle in the cylindrical shell 1 at said step hole 10 two ends;
Said orifice plug 2 is cylindrical and is provided with mesopore; The cylindrical of said orifice plug 2 and said step hole 10 are suitable;
Said throttle bar 3 is located in the mesopore of said orifice plug 2, and the outside diameter of said throttle bar 2 is less than said median pore diameter;
Said fuel inlet fitting 4 is barrel-shaped with delivery connection 5, on the cylindrical of bung, is respectively equipped with outside thread; Said fuel inlet fitting 4 is respectively equipped with oil inlet hole 40 and oil outlet 50 with the barrel-shaped bottom of said delivery connection 5;
Said fuel inlet fitting 4 is connected with said oil-feed direction internal thread segment through its outside thread;
Said delivery connection 5 is connected with said fuel-displaced direction internal thread segment through its outside thread;
Said orifice plug 2 is fixed between said fuel inlet fitting 4 and the delivery connection 5.
Be arranged with the step circle 41 of diameter towards the bucket bottom on said fuel inlet fitting 4 cylindricals, be arranged with the step circle 51 of diameter towards the bucket bottom on said delivery connection 5 cylindricals less than said internal thread less than said internal thread;
Said oil inlet hole 40 is located on the surface of said fuel inlet fitting 4 step circle 41, and said oil outlet 50 is located on the surface of said delivery connection 5 step circle 51.
Filler opening 40 on the said fuel inlet fitting 4 be located at said fuel inlet fitting 4 bottom end and with said fuel inlet fitting 4 concentrics; The groove 31 that the end surface of said throttle bar 3 is offered.
The tail end of said throttle bar 3 is conical, and the bucket bottom center position of said delivery connection 5 is provided with the conical adaptive groove 52 with said throttle bar 3 tail ends.When adopting this kind structural type, no matter the flow controller axis is in any angle, all can utilize the pressure of lubricant oil to make throttle bar 3 and flow controller concentric, and then the hydraulic oil that forms the circular crosssection is crossed ebb interval 6.
Said throttle bar 3 outer surfaces are provided with spiral chute 30.
Offer straight groove on the end face of said fuel inlet fitting 4 step circle 41 and delivery connection 5 step circle 51.
First kind of mode of execution of the present invention is as shown in Figure 2, utilizes fuel inlet fitting 4, delivery connection 5 to be threaded with cylindrical shell 1, and orifice plug 2 is stuck on the fixed position in the cylindrical shell 1; The flow controller of packing into, lubricant oil 7 flow to the flow controller place, because fuel inlet fitting 4 is connected with cylindrical shell 1 inner thread, makes that lubricant oil 7 can only be in oil inlet hole 40 inflow orifice plugs 2; The throttle bar 3 that in orifice plug 2, is provided with, its diameter be less than orifice plug 2 inner diameters, makes that lubricant oil 8 only can 6 inflows from the gap between orifice plug 2 and the throttle bar 3; Because the throttle bar 3 of different size is different with the gap 6 between the orifice plug 2, has realized effective control of different flow; Final lubricant oil 7 flows out through oil outlet 50.
