Abstract
The utility model belongs to the technical field of diesel engine core spare part high pressure electronic control fuel injection pump assembly, in particular to new -type automatically controlled monoblock pump interior buffer structure. This new -type automatically controlled monoblock pump interior buffer structure includes the pump body, inside control valve and the dog, its characterized in that of being equipped with of the pump body: the inside buffer block that is equipped with of dog, be equipped with the spring holder on the inner wall of dog one side, be equipped with compression spring between buffer block and the spring holder. Simple structure, convenient to use, reduce the striking strength of control valve with the dog greatly, guaranteed the lift of control valve better, lengthened automatically controlled monoblock pump's life, the cost is with low costs, and the facilitate promotion is used.
Description
(1) technical field
This utility model relates to a kind of new-type electronically controlled unit pump cushion inner structure, belongs to diesel engine kernel component high pressure
Electronic control injection pump assembly technical field.
(2) background technology
Electronic Unit Pump Fuel Injection System be a kind of high spray, that high oil mass and injection timing all can control flexibly is automatically controlled
Injection system, expulsion pressure is up to more than 120MPa, and its control valve required precision is much higher relative to normal mechanical pump, existing electricity
Electronic control injection pump assembly block of restricted control valve lift in its pump housing that control monoblock pump Diesel engine uses, in work
During control valve and block hard contact, along with control valve moves back and forth with the high speed of 1200 beats/min, control valve is directly hit
Hit block, cause block and control valve both ends of the surface gouging abrasion, reduce the service precision of electric control pump control valve, because being inhaled by electric magnet
The scope of gravitation limits and whole electric control pump initial failure will be made to scrap.
(3) utility model content
This utility model is in order to make up the defect of prior art, it is provided that a kind of simple in construction, can effectively reduce control valve
The strength clashed into mutually with block both ends of the surface in reciprocatory movement, such that it is able to extend the service life of electronically controlled unit pump
New-type electronically controlled unit pump cushion inner structure.
This utility model is achieved by the following technical solution:
A kind of new-type electronically controlled unit pump cushion inner structure, including the pump housing, pump body is provided with control valve and block, and it is special
Levying and be: be provided with buffer stopper inside described block, block side inwall is provided with spring base, sets between buffer stopper and spring base
There is compression spring.
Wherein:
Described buffer stopper stretches out the length of block and is the lift of control valve, the length of buffer stopper and the lift of control valve
Match.
This utility model is realized by following operation principle: this utility model utilizes the bullet of compression spring in spring base
Power acts on buffer stopper, makes control valve end face flexibility connect with block after acting on buffer stopper in control valve moves back and forth again
Touch, substantially reduce the shock strength of control valve and block, thus better ensure that the used lift of control valve, extend electricity
In the service life of control monoblock pump, save the cost of user.
The beneficial effects of the utility model are: simple in construction, easy to use；Substantially reduce the shock of control valve and block
Strength, better assures that the lift of control valve, extends the service life of electronically controlled unit pump；Cost is low, it is simple to promote
Application.
(4) accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is further described.
Accompanying drawing 1 is this utility model electronically controlled unit pump structural representation；
Accompanying drawing 2 is this utility model stop block structure schematic diagram；
Accompanying drawing 3 is tradition electronically controlled unit pump structural representation.
In figure: 1, the pump housing；2, control valve；3, block；4, buffer stopper；5, spring base；6, compression spring.
Detailed description of the invention
Accompanying drawing is specific embodiment of the utility model.
This utility model new-type electronically controlled unit pump cushion inner structure as depicted in figs. 1 and 2, including the pump housing 1, the pump housing 1
Inside is provided with control valve 2 and block 3, and described block 3 is internal is provided with buffer stopper 4, and block 3 side inwall is provided with spring base 5,
Being provided with compression spring 6 between buffer stopper 4 and spring base 5, buffer stopper 4 stretches out the length of block 3 and is the lift of control valve 2, slow
The lift of the length and control valve 2 of rushing block 4 matches.
If Fig. 3 is tradition electronically controlled unit pump structural representation, including the pump housing 1, the pump housing 1 is internal is provided with control valve 2 and block
3。
Compared with tradition electronically controlled unit pump, this utility model utilizes the elastic force of compression spring 6 in spring base 5 to act on buffering
On block 4, control valve 2 end face flexibility is made to contact with block 3, significantly after acting on buffer stopper 4 again in control valve 2 moves back and forth
Reduce the shock strength of control valve 2 and block 3, thus better ensure that the used lift of control valve 2, extend automatically controlled list
In the service life of body pump, save the cost of user.
Claims (3)
1. a new-type electronically controlled unit pump cushion inner structure, including the pump housing (1), the pump housing (1) is internal is provided with control valve (2) and gear
Block (3), it is characterised in that: described block (3) is internal is provided with buffer stopper (4), and block (3) side inwall is provided with spring base
