Description

A kind of electronically controlled unit pump plunger stopper
Technical field
This utility model belongs to monoblock pump field, is specifically related to a kind of electronically controlled unit pump plunger stopper.
Background technology
Monoblock pump is by plunger, plunger guide bush, return spring, spring base, delivery valve, delivery valve seat, oil outlet valve spring, fuel-displaced The part compositions such as valve clamping nut, existing monoblock pump is the structure that electronically controlled unit pump plunger links together with the pump housing, its dress Putting employing installation clip prevents plunger from coming off, and this method needs to have C word groove on the pump housing and installs clip, and the pump housing leaves C word Groove can destroy the integrity of pump housing plunger mesopore, have impact on processing characteristics, and final mating plate precision produces adverse consequences;It is additionally Leaving suitable installing space, the pump housing has to lengthen, and pump housing lengthening can increase difficulty of processing;Another kind of method is passed through Keeping putting being stamped with tongue, tongue snaps in the draw-in groove of the pump housing, and this structure can cause keeping set mounting or dismounting inconvenient, and keeps The tongue of set is easily damaged in assembling and dissembling process, becomes disposable parts.
Utility model content
Technical problem to be solved in the utility model is to provide the structure letter of a kind of electronically controlled unit pump plunger stopper Single, convenient and practical, mounting or dismounting can be repeated and utilize, be difficult to lose efficacy, pump housing length is more reasonable, structure is compacter.
A kind of electronically controlled unit pump plunger stopper, including under the pump housing, plunger, back-up ring, holding set, plunger spring, spring Seat and circlip groove, described plunger at one end is arranged in the pump housing, and described spring lower seat is arranged on the plunger other end, described plunger spring Being centered around outside plunger, described holding is set between plunger spring and plunger, and described holding set is provided with back-up ring with the pump housing Groove, the circlip groove that described holding puts works in coordination with the circlip groove on the pump housing, and described back-up ring is arranged in pump housing circlip groove.
Preferably, described back-up ring is elastic spring.
Preferably, the circlip groove that described holding puts and the circlip groove on the pump housing are semicircle.
Preferably, described holding set is provided with through hole.
Beneficial effect:
(1) simple in construction, convenient and practical of a kind of electronically controlled unit pump plunger stopper of the present utility model, can repeat Mounting or dismounting utilize, and are difficult to lose efficacy, and pump housing length is more reasonable, structure is compacter.
(2) a kind of electronically controlled unit pump plunger stopper of the present utility model, this device passes through on the pump housing and keeps set Elastic spring mounting groove coordinates screens with steel wire, it is achieved prevent plunger from dropping, and does not destroy pump housing plunger mesopore, and processing is very Convenient, element precision is guaranteed.
Accompanying drawing explanation
Fig. 1 is the pump housing and the structural representation keeping set;
Fig. 2 is the B station enlarged drawing of Fig. 1;
The 1-pump housing, 2-plunger, 3-back-up ring, 4-keeps set, 5-plunger spring, 6-spring lower seat, 7-circlip groove.
Detailed description of the invention
Further illustrate embodiment of the present utility model below in conjunction with the accompanying drawings.
Embodiment 1
A kind of electronically controlled unit pump plunger stopper, including the pump housing 1, plunger 2, back-up ring 3, keeps set 4, plunger spring 5, bullet Seat 6 and circlip groove 7 under spring, described plunger 2 one end is arranged in the pump housing 1, and described spring lower seat 6 is arranged on plunger 2 other end, institute State plunger spring 5 to be centered around outside plunger 2, described keep set 4 to be arranged between plunger spring 5 and plunger 2, described keep set 4 with The pump housing 1 is provided with circlip groove 7, and the described circlip groove 7 kept on set 4 is worked in coordination with the circlip groove 7 on the pump housing 1, described gear Circle 3 is arranged in the pump housing 1 circlip groove 7, and described back-up ring 3 is elastic spring, and described holding is overlapped on the circlip groove 7 on 4 and the pump housing 1 Circlip groove 7 is semicircle, and described holding set 4 is provided with through hole.
Worked in coordination with keeping the circlip groove 7 on set 4 by the circlip groove 7 on the pump housing 1, then between two circlip grooves 7 Back-up ring 3 is installed so that it is forming position is poor, makes plunger 2 to drop out.
Being described in detail specific embodiment of the utility model above, but it is intended only as example, this practicality is new Type is not restricted to above description specific embodiment.To those skilled in the art, any this utility model carried out Equivalent modifications and replacement are the most all among category of the present utility model.Therefore, without departing from spirit and scope of the present utility model Lower made impartial conversion and amendment, all contain in the range of this utility model.
