Description
Technical Field
The utility model relates to a high-pressure petrol injection system, in particular to automobile engine fuel sprayer valve body.
Background
When the engine works, many parts move relatively at high speed, and if the surfaces of the parts are not lubricated, strong friction can be generated between the parts; some parts can be lubricated by the lubricating oil path, and some parts can not be lubricated by the lubricating oil path, and the parts need the oil nozzle for lubrication.
The traditional oil nozzle is a plurality of tiny metal bent pipes which are directly pressed on a cylinder body or other parts; the oil nozzle needs special tools during installation, and is easy to fall off in the using process to damage other parts; the maintenance is also inconvenient and the injection pressure of the oil is not large because special tools are needed.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model aims to provide an injection nozzle valve body for engine lubrication mechanism who is difficult for droing, easy to assemble and maintenance.
The above technical purpose of the present invention can be achieved by the following technical solutions:
the fuel spray nozzle valve body of the automobile engine comprises a valve body, wherein the valve body is in a rod shape, one end of the valve body is a hexagonal head, the other end of the valve body is a main rod, the main rod sequentially comprises a circular table section, a parallel section, a middle section and a tail section, a first inner hole extending into the circular table section is formed in the axis center of the middle section, a second inner hole communicated with the first inner hole is formed in the tail section, the diameter of the second inner hole is slightly larger than that of the first inner hole, and the second inner hole partially extends into the middle section; two large cross holes which are crossed in a cross shape are formed in the parallel section, one large cross hole penetrates through two symmetrical sides of the parallel section, and the other large cross hole is formed in the half thickness of the parallel section and is communicated with the first inner hole; the tail section is provided with two small cross holes which are crossed in a cross manner, and the two small cross holes penetrate through the symmetrical two sides of the tail section; the annular groove is formed in the end, not connected with the middle section, of the tail section, and the annular groove and the second inner hole are coaxially arranged and are larger than the second inner hole in diameter.
To sum up, the utility model discloses the beneficial effect who contrasts in prior art does: through designing neotype fuel sprayer valve body structure, realized being difficult for droing when the installation is used, and installation easy maintenance.
