The installation device is used for fully cooling the fuel injector, thus the blockage of the fuel injector due to overhigh heat load is reduced, the reliability of the fuel injector is improved, and the faults of the fuel injector are reduced.
Description
Technical field
The invention belongs to parts of internal-combustion engine, be specifically related to a kind of oil sprayer erecting device that has independent cooling space.
Background technique
In the internal combustion engine process, oil sprayer not only receives the thermal radiation of water cavity on every side, and self also produces a large amount of heat loads, thereby must fully cool off oil sprayer.
At present, the internal-combustion engine oil sprayer mainly is fixed on cylinder head or the body through pressing plate and clamping bolt, and the oil injector body surrounding space is limited, makes the oil injector body cooling effect not good, causes the catching phenomenon that oil sprayer brings because of heat load is too high.
Summary of the invention
The present invention is exactly too high in order to solve the oil sprayer heat load, makes the oil sprayer clamping stagnation and the problem of cisco unity malfunction.
Technological scheme of the present invention:
A kind of oil sprayer erecting device that has independent cooling space; Comprise base, sealing body, O type rubber seal, pressing plate, clamping bolt and oil injector body; At the inner independent cooling space that forms sealing of oil sprayer erecting device, the cooling liquid that oil injector body is cooled off flows in the sealing space.
Wherein, this independent cooling space is made up of base, sealing body, two O type rubber seal jointly; Center has one, and base can be divided into three parts in upper, middle and lower in order to hold the circular hole of oil injector body, and the radius of upper and lower is consistent, and the radius at middle part is significantly less than the upper and lower; Also there is a circular hole at sealing body center, and circular hole internal diameter and base top, bottom radius are consistent, can be enclosed within on the base, closely cooperates with the upper and lower of base; Base and sealing body, at junction plane place, the upper and lower of base, each seals with an O type rubber seal, thus the common independent cooling space that constitutes sealing at the base middle part; In the position of independent cooling space, respectively there is a mouth sealing body both sides, and a side mouth is nearer apart from the base bottom, the import that gets into independent cooling space as cooling liquid; The opposite side mouth is nearer apart from base top, discharges the outlet of independent cooling space as cooling liquid; The exit position is apparently higher than entrance location, and cooling liquid can be full of independent cooling space basically, forms complete cooling circuit system.
This oil sprayer erecting device, base and sealing body two bolts hole that respectively are being symmetrically distributed in the both sides, bottom, two cover bolts hole are aimed at respectively and with after the bolt, base and sealing body relative fixed, and whole device is fixed on body or the cylinder head; There is a non-circular hole in order to the relative rotational slide of prevention oil sprayer erecting device and oil injector body at the pressing plate center, is stuck in the groove of oil injector body corresponding position; The top of base two bolts hole that are being symmetrically distributed, the pressing plate both sides each with a clamping bolt, pressing plate is fixed on base top, pressing plate and base relative fixed; Oil injector body utilizes pressing plate and clamping bolt to be fixed on the base.
Beneficial effect of the present invention:
Around oil sprayer, be provided with independently cooling space; Oil sprayer is fully cooled off, reduce the oil injector body temperature, reduce oil sprayer because of the too high catching phenomenon that causes of too high, the inner precision pair Yin Wendu of heat load; Improve the reliability of oil sprayer, reduced the oil sprayer fault.

Embodiment
A kind of oil sprayer erecting device that has independent cooling space; Comprise base, sealing body, O type rubber seal, pressing plate, clamping bolt and oil injector body; At the inner independent cooling space that forms sealing of oil sprayer erecting device, the cooling liquid that oil injector body is cooled off flows in the sealing space.
Wherein, this independent cooling space is made up of base, sealing body, two O type rubber seal jointly; Center has one, and base can be divided into three parts in upper, middle and lower in order to hold the circular hole of oil injector body, and the radius of upper and lower is consistent, and the radius at middle part is significantly less than the upper and lower; Also there is a circular hole at sealing body center, and circular hole internal diameter and base top, bottom radius are consistent, can be enclosed within on the base, closely cooperates with the upper and lower of base; Base and sealing body, at junction plane place, the upper and lower of base, each seals with an O type rubber seal, thus the common independent cooling space that constitutes sealing at the base middle part; In the position of independent cooling space, respectively there is a mouth sealing body both sides, and a side mouth is nearer apart from the base bottom, the import that gets into independent cooling space as cooling liquid; The opposite side mouth is nearer apart from base top, discharges the outlet of independent cooling space as cooling liquid; The exit position is apparently higher than entrance location, and cooling liquid can be full of independent cooling space basically, forms complete cooling circuit system.
This oil sprayer erecting device, base and sealing body two bolts hole that respectively are being symmetrically distributed in the both sides, bottom, two cover bolts hole are aimed at respectively and with after the bolt, base and sealing body relative fixed, and whole device is fixed on body or the cylinder head; There is a non-circular hole in order to the relative rotational slide of prevention oil sprayer erecting device and oil injector body at the pressing plate center, is stuck in the groove of oil injector body corresponding position; The top of base two bolts hole that are being symmetrically distributed, the pressing plate both sides each with a clamping bolt, pressing plate is fixed on base top, pressing plate and base relative fixed; Oil injector body utilizes pressing plate and clamping bolt to be fixed on the base.
