Inner chamber air inlet side, another spray orifice is just to piston cavity exhaust side.
The valve body is provided with the potted component for closing the valve body.
The valve inner is provided with spring and steel ball, and the steel ball is arranged on the valve body and connects with the oil duct of engine body
On logical hole, the pressure of spring makes the hole connected with the oil duct of engine body of steel ball closed valve.
The cap of spraying nozzle is detachably connected with the mozzle.
A technical scheme in above-mentioned technical proposal has the following advantages that or beneficial effect, piston cooling nozzle is opened
Open pressure and oil spout assignment of traffic is designed, so as to the thermic load and cooling nozzles working characteristics of engine are contacted one
Rise, when engine oil pressure reaches to a certain degree, the piston cooling nozzle ejects two beam machine oil simultaneously, respectively to piston
Inner chamber intake and exhaust survey carries out sufficiently cool so that the whole head of piston produces violent heat exchange, and to piston crown temperature, it is carried out
Cooling, it is to avoid cause the phenomenons such as lubricating oil adhesion because temperature is too high, while combustion knock tendency can be reduced effectively, improves
Engine fuel is consumed, and piston cooling nozzle closing is reached when engine oil pressure is relatively low, and this allows for engine in idling
During with light running, the mechanical loss of lubricating oil pump is greatly reduced, improve the fuel economy of engine.

Specific embodiment
It is new to this practicality below in conjunction with accompanying drawing to make the purpose of this utility model, technical scheme and advantage clearer
Type implementation method is described in further detail.
Referring to Fig. 1-2, a kind of piston of automobile engine cooling nozzles have：
Valve body, it is connected with the oil duct of engine body；
Mozzle, connects with valve inner；
Cap of spraying nozzle, the end of confined bed flow tube, cap of spraying nozzle is provided with two spray orifices, and a spray orifice is just to piston cavity air inlet
Side, another spray orifice is just to piston cavity exhaust side.
Valve body is provided with the potted component of closed valve.
Valve inner is provided with spring and steel ball, and steel ball is arranged on the hole that valve body is connected with the oil duct of engine body, bullet
The pressure of spring makes the hole connected with the oil duct of engine body of steel ball closed valve.
Cap of spraying nozzle is detachably connected with mozzle.
Cooling nozzles include warm detachable cap of spraying nozzle design.By pressure-sensing device induction oil pressure, and drive
A set of valve mechanism, when engine oil pressure is higher, valve is opened, and machine oil is ejected into piston from the cooling nozzles of two different directions
Inner chamber intake and exhaust are surveyed, and piston are carried out sufficiently cool, and when engine oil pressure is relatively low, valve closing is not cooled down to piston, is saved
Oil flow rate.
At piston cooling nozzle, using cap of spraying nozzle design result, two spray orifices are processed on cap of spraying nozzle, by different sprays
The injection diameter design of mouth cap carries out rational cooling control to piston cavity intake and exhaust side, and nozzle arrangements master-plan has more
Plus the effect of practicality, the nozzle cap of different pore size can be changed according to the requirement cooled down to piston of different engines, reach
To different cooling effects.
Piston cooling nozzle includes three systems, as illustrated, first systematic is nozzle system, by cap of spraying nozzle, water conservancy diversion
Pipe and valve seat composition, it is to ensure that cooling nozzles carry out cooling injection with certain spray angle and flow to piston.Second
System is fit sealing system, by fastening bolt and potted component, the oil duct of nozzle and engine body is connected
Together, and the space of cooling nozzles steel ball is provided.3rd system is execution system, is made up of spring and steel ball.
When engine heat load increases, the pinking tendency of engine can also increase, and at this moment need to engine piston head
Portion carries out cooling control, when engine oil pressure reaches the design pressure of piston cooling nozzle unlatching, piston cooling nozzle
Open, open the valve of piston cooling nozzle, machine oil carries out spray cooling by piston cooling nozzle to piston crown.Injection
Process is that double oil beam machine oil distribute injection according to its oil mass for designing simultaneously, piston cavity intake and exhaust is surveyed and is fully closed simultaneously
The cooling of reason.
When engine is unexpected when rotating speed higher is operated to idling operation, because oil temperature is higher, piston cooling
Nozzle is also in opens spray regime, and engine oil pressure can be caused relatively low, and return spring drives steel ball closure piston cooling nozzles, living
Plug cooling nozzles are stopped.
Piston cavity intake and exhaust are surveyed using double oily beam nozzle arrangements designs carry out the spray cooling of different flow, reaches and fills
Divide the effect of rational cooling piston crown temperature.
Cooling nozzles are designed comprising detachable cap of spraying nozzle.By pressure-sensing device induction oil pressure, and drive one
Set valve mechanism, when engine oil pressure is higher, valve is opened, and machine oil is ejected into piston from the cooling nozzles of two different directions
Chamber intake and exhaust are surveyed, and piston are carried out sufficiently cool, and when engine oil pressure is relatively low, valve closing is not cooled down to piston, saves machine
Oily flow.
Two spray orifices are processed on cap of spraying nozzle, the design has more practical to piston cooling spray nozzle structure master-plan
Effect, can change according to different engines to oily beam diameter and the how many requirement of piston intake and exhaust side demand distributive value
The nozzle cap of different pore size, reaches different cooling effects.
After using above-mentioned structure, Opening pressure and oil spout assignment of traffic to piston cooling nozzle are designed, so that
The thermic load and cooling nozzles working characteristics of engine are linked together, when engine oil pressure reaches to a certain degree,
The piston cooling nozzle ejects two beam machine oil simultaneously, piston cavity intake and exhaust survey is carried out respectively sufficiently cool so that piston
Whole head produces violent heat exchange, and to piston crown temperature, it is cooled down, it is to avoid cause lubricating oil viscosity because temperature is too high
The phenomenon such as, while combustion knock tendency can be reduced effectively, improve engine fuel consumption, when engine oil pressure is relatively low
Time reaches piston cooling nozzle closing, and this allows for engine in idling and light running, greatly reduces lubricating oil pump
Mechanical loss, improves the fuel economy of engine.
The utility model is exemplarily described above in conjunction with accompanying drawing, it is clear that the utility model is implemented not to be received
The limitation of aforesaid way, as long as employing changing for the various unsubstantialities that method design of the present utility model and technical scheme are carried out
Enter, or it is not improved by it is of the present utility model design and technical scheme directly apply to other occasions, in the utility model
Protection domain within.
