Description
Technical field
The utility model is related to piston of automobile cooling technology field, and in particular to a kind of piston of automobile engine cooling spray
Mouth.
Background technology
At present, improved with the performance of engine, the caloric value of engine is increasing.Only rely on flying for internal machine oil
Splash, and metal heat-conducting can not meet cooling requirements to take away heat energy.Produced when engine is worked with high-power output
Heat energy when can not be pulled away in time, temperature will more and more higher, piston works at high temperature for a long time, it is easy to produce casing wall drawing
The problems such as wound, detonation.In order to solve the problem of temperature is too high under high-power operation, it is necessary to design it is a kind of to engine piston more
The device efficiently cooled, makes the heat energy on piston be taken away in time, it is ensured that the normal operation of engine.
The cooling of conventional engines piston a, part takes away heat mainly by the mist of oil in inner air, and a part leans on cylinder
Body thermal conductivity takes away heat energy, and heat dispersion is poor.In the running of engine high-efficiency, the probability that breaks down ratio uses piston
The engine of cooling nozzles is high.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of piston of automobile engine cooling nozzles, to solve hair
The problem of motivation radiates not in time when running at high speed.
For realize technical scheme that the purpose of this utility model uses for：A kind of piston of automobile engine cooling nozzles, its
It is characterised by, including spray bar, control assembly, the control assembly sets aisled pedestal, the oil spout including an inside
One of outlet UNICOM of pipe and path on the pedestal, the path is provided with a plunger for carrying spring reset, institute
State the opening and closing of plunger control access.
Further, the bottom of the spring is provided with fixed block, and the fixed block is embedded between the pedestal and using pressure
Riveting mode of texturing.
Further, another outlet of the path is located at the top of pedestal.
Further, the pedestal profile is revolving body.
Further, the plunger and spring are arranged in a sliding cavity in pedestal.
Further, the outer surface of upper of the pedestal is provided with external screw thread.
The beneficial effects of the utility model：
A kind of piston of automobile engine cooling nozzles that the utility model is provided have advantages below：
Piston cooling nozzle plays a part of cooling down piston on the engine, and fluid is ejected into piston, and can root
Oil spout state is opened and closed according to the operating mode of engine；Fixed block is mounted in macropore and pressed, it is ensured that plunger will not take off with spring
Go out.
Brief description of the drawings
Fig. 1 is the structural representation for the piston of automobile engine cooling nozzles that the utility model is provided；
Fig. 2 is the assembling schematic diagram of the piston of automobile engine cooling nozzles of the utility model offer on the engine.
Embodiment
The utility model is described in further detail below by specific embodiment and with reference to accompanying drawing.
Fig. 1 shows the structure of piston of automobile engine cooling nozzles, including spray bar 6, control assembly 12, control assembly
12 set aisled pedestal 7, one of outlet UNICOM of spray bar 6 and path on pedestal 7, in this implementation including an inside
In example, the lane entrance in pedestal 7 is exported in the side of pedestal, path has a turning, is set on path in the top of pedestal
Have a plunger 8 resetted with spring 9, plunger 8 is located exactly at the corner of path, spring 9 as plunger 8 and pedestal 7 it
Between, spring 9 is fixedly connected with plunger, and the other end of spring 9 is connected by fixed block 10 with pedestal 7, work of the plunger 8 in spring 9
Under, moved up and down in sliding cavity 11, the opening and closing of control access.And the decrement of spring 9 is by path pressure at two ends difference
Control, the size of pressure differential comes from the height of engine speed.
In the present embodiment, fixed block 10 is embedded in the bottom of pedestal 7, and using the mode of texturing that presses.
In the present embodiment, the profile of pedestal 7 is revolving body, and the outer surface of upper of pedestal 7 is provided with external screw thread.
Fig. 2 shows the assembling schematic diagram of piston of automobile engine cooling nozzles 5, and piston component includes piston 2, piston and connected
Bar 1, cooling nozzles 5 are connected by the external screw thread at the top of pedestal 7 with cylinder body working connection 4.
When engine speed is not high, when power output is little, the heat energy that piston 2 is produced is few, it is not necessary to which piston is cold
But nozzle 5 cools for its oil spout.Because engine speed is not high, the working connection oil pressure acted on plunger 8 is relatively low, with oil pressure phase
The reaction force that the spring 9 of matching is produced makes plunger 8 can not be moved to the position for opening oil circuit, and working connection can not be cold by piston
But nozzle is ejected on piston.
When engine output increase is big, when rotating speed is improved, working connection pressure increases therewith.Pressure acts on plunger 8
On, make the compression spring 9 of plunger 8, therewith oil pressure matching spring 8 under the effect of the pressure, can allow embolism 8 be moved to beat
Open oil circuit state.Now machine oil, by spray bar 6, acts on piston from engine cylinder-body working connection by the path in pedestal 7
Bottom 3.
Preferred embodiment of the present utility model is the foregoing is only, the utility model is not limited to, for this area
Technical staff for, the utility model can have various modifications and variations.It is all it is of the present utility model spirit and principle within,
Any modification, equivalent substitution and improvements made etc., should be included within protection domain of the present utility model.
