Abstract
The utility model discloses a kind of injection pump oil mass limits device, including adjusting screw, ratch sheath and ratch, it is characterised in that：Nut is cased in the adjusting screw, the adjusting screw is connect across ratch sheath with ratch, and the nut is located at the outside of ratch sheath.Compared with prior art, the beneficial effects of the utility model are：The utility model has debugged laggard quadrat in injection pump and has been honored as a queen the random change that prevents to injection pump fuel delivery, effectively prevents the degree of danger of diesel engine and injection pump, improves service life, reduces maloperation.
Description
Technical field
The utility model is related to a kind of limits device, particularly a kind of injection pump oil mass limits device.
Background technology
Injection pump is the heart of diesel engine, and injection pump fuel delivery influences the working performance and service life of diesel engine, existing
Some diesel engine users can change the fuel delivery of injection pump so that maloperation easily occurs for diesel engine work reduced lifetime.
Utility model content
The purpose of this utility model is to provide a kind of injection pump oil mass limits device, to solve in above-mentioned background technology
The problem of proposition.
To solve the above problems, the technical solution adopted in the utility model is：
A kind of injection pump oil mass limits device, including adjusting screw, ratch sheath and ratch, it is characterised in that：It is described
Nut is cased in adjusting screw, the adjusting screw is connect across ratch sheath with ratch, and the nut is located at ratch sheath
Outside.
Preferably, the outside of the adjusting screw, which is equipped with, adjusts sheath.
Compared with prior art, the beneficial effects of the utility model are：The utility model carries out after injection pump is debugged
The random change to injection pump fuel delivery is prevented after lead sealing, effectively raises the service life of diesel engine and injection pump, is reduced
Maloperation.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Wherein, 1- adjusting screws, 2- nuts, 3- adjust sheath, 4- ratch, 5- ratch sheaths.
Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
A kind of injection pump oil mass limits device, including adjusting screw 1, ratch sheath 5 and ratch 4, the adjusting screw 1
On be cased with nut 2, the adjusting screw 1 is connect across ratch sheath 5 with ratch 4, and the nut 2 is located at the outer of ratch sheath 5
Side.The outside of the adjusting screw 1, which is equipped with, adjusts sheath 3.
The utility model is fixed adjusting screw 1 by nut 2, so as to limit the movement of injection pump ratch so that tooth
The stroke of bar is limited, it is impossible to be changed to bigger oil mass direction, injection pump fuel delivery is made to be limited in the factory state of design.
While there has been shown and described that the embodiment of the utility model, for the ordinary skill in the art,
It is appreciated that can these embodiments be carried out with a variety of variations in the case of the principle and spirit for not departing from the utility model, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
