IP India · live recordAbstract
The fuel injection pump 10 comprises a plunger 12 positioned in a barrel 14, one end of the plunger 12 is connected to a spring plate 16. The pump 10 comprises 5 a spring 18 located at a bottom portion 15 of the barrel 14. The pump 10 comprises a supporting element 20 fitted at the bottom portion 15 of the barrel 14, such that a portion of the spring 18 encounters the supporting element 20, restricting a movement of the spring 18. With the above-disclosed supporting element 20, the position of the spring 18 is 10 maintained in a single location without any displacement during the handling process.

Claims:1. A fuel injection pump (10) comprising : - a plunger (12) positioned in a barrel (14), one end of the plunger (12) is connected to a 5 spring plate (16); - a spring (18) located at a bottom portion (15) of said barrel (14) ; characterized in that: - a supporting element (20) fitted at said bottom portion (15) of said barrel (14), such that a portion of said spring (18) encounters said 10 supporting element (20), restricting a movement of said spring (18). 2. The fuel injection pump (10) as claimed in claim 1, wherein said supporting element (20) is in a form of a ring/circular/non-circular structure with at least two extensions (22) made on said supporting element (20). 3. The fuel injection pump (10) as claimed in claim 2, wherein said at least two extensions (22) are made in the form of a claw-shape or “C” shape and are integrated into said supporting element (20). 4. The fuel injection pump (10) as claimed in claim 1, wherein said supporting element (20) is fitted to said bottom portion (15) of said barrel (14) using at least one fitting techniques comprising a press-fit, a snap fit, a fastener. 5. The fuel injection pump (10) as claimed in claim 1, wherein dimensions of 25 said supporting element (20) is made corresponding to dimensions of said spring (18) and said bottom portion (15) of said barrel (14). 6. The fuel injection pump (10) as claimed in claim 1, wherein said supporting element (20) is made of a flexible material and said supporting element (20) 30 is chosen from a group of materials comprising a sheet metal, a high grade plastic material and the like. 7. The fuel injection pump (10) as claimed in claim 1, wherein a top dead coil (24) of said spring (18) is held by at least two extensions 5 (22), when said spring (18) is pushed into said supporting element (20) during assembly. 8. The fuel injection pump (10) as claimed in claim 7, wherein said at least two extensions (22) moves away while assembling said spring (18) into said 10 supporting element (20). 9. The fuel injection pump (10) as claimed in claim 7, wherein due to the position of said top dead coil (24) of said spring (18) in said at least two extensions (22) of said supporting element (20), said movement of said 15 spring (18) is restricted. , Description:The fuel injection pump 10 comprises a plunger 12 positioned in a barrel 14, one end of the plunger 12 is connected to a spring plate 16. The pump 10 comprises 5 a spring 18 located at a bottom portion 15 of the barrel 14. The pump 10 comprises a supporting element 20 fitted at the bottom portion 15 of the barrel 14, such that a portion of the spring 18 encounters the supporting element 20, restricting a movement of the spring 18. With the above-disclosed supporting element 20, the position of the spring 18 is 10 maintained in a single location without any displacement during the handling process.
