Abstract
The utility model provides a piston cooling nozzle, which structurally comprises a nozzle body with a nozzle pipe, wherein an oil inlet passage and an oil outlet passage communicated with the nozzle pipe are arranged in the nozzle body, a ring-shaped step is formed at the joint of the oil inlet passage and the oil outlet passage, a ball plug is arranged in the oil outlet passage, the diameter of the ball plug is larger than the caliber of the ring-shaped step and smaller than the caliber of the oil outlet passage, and the ball plug is pushed to prop up against the ring-shaped step by pressure springs fixed in the oil outlet passage. Compared with the cooling nozzle under a traditional direct connection state, the piston cooling nozzle has the advantages as follows: by increasing the pressure springs capable of being adjusted according to the needs of the system, the opening pressure of the cooling nozzle is guaranteed to be under a reasonable range, unnecessary power loss of an engine is reduced, meanwhile, low oil pressure of an engine under a low speed is prevented, and the reliable lubrication of the engine is ensured.
Description
Technical field
The utility model relates to the engine cooling technology, is specifically related to a kind of piston cooling nozzle.
Background technique
Along with reaching its maturity of internal-combustion engine technology, power per liter is increasing, and in order to guarantee motor in running, piston crown is unlikely overheated, need cool off piston crown.At present, the piston cooling nozzle on the big multiple-motor is a pass-through state, and promptly motor is after startup, and cooling jet is a commencement of fuel injection.Yet motor is under lower-speed state, and it is very little to load, and heating value is little, there is no need motor is cooled off.If this moment, piston cooling nozzle was still opened, can cause the power loss of motor to increase on the one hand, oil consumption increases, can cause that on the other hand oil pressure is on the low side under the lower-speed state, particularly under the engine thermal idling mode, whole system pressure can not satisfy the demand of motor, and each friction pair wearing and tearing aggravates, and influences the life-span of motor.
Summary of the invention
Technical problem to be solved in the utility model is the piston cooling nozzle that can open and close automatically according to the variation of motor main oil gallery pressure.
According to the utility model proposes piston cooling nozzle, comprise the nozzle body that has nozzle pipe, the oil discharge passage that has oil inlet passage in the described nozzle body and be communicated with described nozzle pipe, key is that described oil inlet passage and oil discharge passage joint form circular step, be provided with ball plug in the described oil discharge passage, the diameter of described ball plug is greater than the bore of described circular step and less than the bore of oil discharge passage, ball plug is leaned on described circular step by the stage clip that is fixed in the oil discharge passage.
Piston cooling nozzle of the present utility model, can adjust the pressure size of stage clip as required, has only oil inlet passage pressure like this when piston cooling nozzle, when just motor main oil gallery pressure increases to a certain degree, the suffered machine oil hydraulic power of ball plug just can be greater than the pressure of stage clip, thus compression press spring, and ball plug moves, oil inlet passage and oil discharge passage conducting, the cooling jet commencement of fuel injection.So just guaranteed that piston cooling nozzle can open and close automatically according to the pressure of motor main oil gallery pressure, avoided motor to open and caused the engine motor oil hypotony at idling mode lower piston cooling jet, the problem that engine scuffing is excessive has reduced the motor unnecessary power loss.
Described nozzle body side is outward extended with the mounting flange face, and the nozzle body side also is provided with the O RunddichtringO.Nozzle body can be tightened on the engine cylinder-body by bolt and mounting flange face like this, cooperates the O RunddichtringO, guarantees that nozzle body is installed in the sealing of engine cylinder-body, prevents that machine oil from leaking.
The head of the nozzle pipe of described nozzle body adopts the design of convergent mouth, to improve the pressure and the machine oil flow velocity at oil outlet place, guarantees cooling effect.
Described stage clip is fixed in the oil discharge passage by supporting base, and described supporting base has the supporting portion of going deep in the stage clip, guarantees the stability of stage clip.
The utility model is by increasing stage clip, this stage clip can be according to the demand adjustment of system, and the cracking pressure that guarantees cooling jet has reduced the motor unnecessary power loss in reasonable range, simultaneously prevented that also motor engine oil pressure under low speed is on the low side, guaranteed the proper lubrication of motor.

Embodiment
Describe embodiment of the present utility model below in detail.
As Fig. 1,2,3,4,5, piston cooling nozzle of the present utility model, comprise the nozzle body 2 that has nozzle pipe 1, the oil discharge passage 22 that has oil inlet passage 21 in the nozzle body 2 and be communicated with nozzle pipe 1, oil inlet passage 21 forms circular step 23 with oil discharge passage 22 joints, be provided with ball plug 3 in the oil discharge passage 22, the diameter of ball plug 3 is greater than the bore of circular step 23 and less than the bore of oil discharge passage 22, ball plug 3 is leaned on circular step 23 by stage clip 4.Nozzle body 2 sides are outward extended with mounting flange face 24, and nozzle body 2 sides also are provided with O RunddichtringO 25.Nozzle body 2 can be tightened on the engine cylinder-body by bolt and mounting flange face 24 like this, cooperates O RunddichtringO 25, guarantees that nozzle body 2 is installed in the sealing of engine cylinder-body, prevents that machine oil from leaking.The head of nozzle pipe 1 adopts the design of convergent mouth, to improve the pressure and the machine oil flow velocity at oil outlet place, guarantees cooling effect.Stage clip 4 is fixed in the oil discharge passage 22 by supporting base 5, and supporting base 5 has the supporting portion of going deep in the stage clip 4, guarantees the stability of stage clip 4.
The utility model is by increasing stage clip 4, this stage clip can be according to the demand adjustment of system, and the cracking pressure that guarantees cooling jet has reduced the motor unnecessary power loss in reasonable range, simultaneously prevented that also motor engine oil pressure under low speed is on the low side, guaranteed the proper lubrication of motor.
