INVENTOR. Mz22pam JVLYerWes United States Patent DIESEL INJECTION NOZZLE PULLER William M. Yerkes, Ponca City, Okla.
Application March 27, 1957, Serial No. 648,815
1 Claim. (Cl. 29-252) This invention relates to a pulling device, and more particularly to a tool for use in pulling or removing diesel injection nozzles.
The object of the invention is to provide a hydraulically operated tool which will facilitate the removal of diesel engine injectors.
Another object of the invention is to provide a hydraulically operated injection nozzle body puller which will not slip, or spread, and wherein the injection nozzle can be readily removed for repair, replacement or the like.
A further object of the invention is to provide a pulling device which is extremely simple and inexpensive to manufacture.
Other objects and advantages will be apparent during the course of the following description.
In the accompanying drawing, forming a part of this application, and in which like numerals are used to designate like parts throughout the same.
Figure 1 is an elevational view illustrating the pulling device mounted on a diesel engine.
Figure 2 is a sectional view taken through the pulling device of the present invention.
Figure 3 is a transverse sectional view taken through the pulling device and illustrating certain constructional details thereof. 3
Referring in detail to the drawing, the numeral indicates a portion of a conventional diesel engine which is provided with the usual injector nozzle 11. The present invention is directed to a mechanism or tool for use in pulling or removing the injector nozzle 11 as when the nozzle 11 is to be removed or replaced. The injector nozzle 11 forms a part of the nozzle body 9 and according to the present invention the entire body 9 is removed so that the injector nozzle 11 is removed with the body 9.
The tool of the present invention includes an adaptor which is indicated generally by the numeral 12. The adaptor 12 has a substantially cylindrical shape and has an end cut away as an end 13 so that it will conform to the curvature or shape of the diesel block 10. Secured to the outer end of the adaptor 12 or formed integral therewith is a hollow housing 14 which is adapted to be connected to a suitable source of hydraulic fluid under pressure by means of a conduit 15, Figures 1 and 2. Extending through the central portion of the housing 14 and projecting into the adaptor 12 is a movable rod 16.
Secured to the inner end of the rod 16 in any suitable manner, as for example by welding, is a collar or plate 17. The collar 17 is provided with a plurality of slots 18, and suitable securing elements such as bolts 19 extend through the slots 18 and threadedly engage the nozzle body 9.
Extending outwardly from the housing 14 and secured thereto or formed integral therewith, is a plurality of spaced parallel cylinders 20, and movably mounted in each cylinder 20 is a plunger or piston 21. There is further provided a plate 22 which is provided with a central opening 23 whereby a portion of the rod 16 can extend there- 2,883,741 Patented Apr. 28, 195 9 26 abutting the outer surface of the plate 22.
From the foregoing, it is apparent that-there has been provided a tool which is especially suitable for use in removing a diesel injection nozzle, such as the nozzle 11. In use, when the nozzle 11 and nozzle body 9 are to be removed, as for example when these parts are to be replaced or repaired, it is only necessary to place the adaptor 12 over the body 9 as shown in Figures 1 and 2. Then, the bolts 19 are extended through the slots 18 and into engagement with the nozzle body 9. With the parts arranged as shown in the drawing, hydraulic fluid is introduced through the conduit 15 and this hydraulic fluid under pressure enters the housing 14 and then passes up through the cylinders 20. This causes the piston 21 to move outwardly in the cylinders 20 to thereby move the plate 22 since the plate 22 is connected to the pistons 21 by means of the bolts or screws 24. As the plate 22 moves, it moves the rod 16, the nut 26 being arranged in threaded engagement with the rod 16, the nut 26 abutting or engaging the plate 22. As the rod 16 moves through the opening in the center of the housing 14, the collar 17 will be moved and this causes the nozzle body 9 and injector nozzle 11 to be removed from the diesel cylinder head 10. When the bolts 19 are inserted through the slots 18, the rod 16 is moved to a position so that access can be had to the collar 17 and bolts 19. Thus, with the present invention, the nozzle body 9 and the injector nozzle 11 can be readily removed from the diesel engine 10 without the necessity of exerting a great deal of manual eflort and also damage to the parts will be prevented.
Thus, it will be seen that there has been provided a hydraulically operated tool which is especially suitable for use in pulling injection nozzle bodies from diesel engines without slipping, binding, scraping, spreading, or the like. Thus, the tool is especially suitable for use in overhaul and repair of heavy diesel equipment. After the device has been tightened up on the head to start pulling, there will be no damage to the parts since the injector nozzle will be pulled straight out. The cut away portion 13 of the adaptor 12 conforms to the configuration of the body 10. The parts can be made of any suitable material or in any desired shape or size. Due to the provision of the cut away portion 13, the adaptor will align itself when starting to pull so that binding and scraping will be eliminated. The bolts 19 can be arranged in engagement with the usual apertures in the nozzle body after the screws or bolts in the apertures have been removed. Any suitable source of hydraulic fluid under pressure can be used for supplying the fluid through the conduit 15.
What is claimed is:
