Abstract
The utility model provides a nozzle for cooling of a piston, which comprises a nozzle body and a nozzle plug. The nozzle plug is provided with an oil inlet passage and an oil outlet passage communicated with a nozzle pipe of the nozzle body, an annular step is formed at the connecting joint of the oil outlet passage and the oil inlet passage, a plunger butted by a spring is arranged in the oil outlet passage, the shape of the plunger matches with that of the oil outlet passage, and the plunger is butted against the annular step. Since a ball valve of the conventional nozzle for cooling of a piston is replaced by the plunger, action force on the nozzle for cooling of a piston is uniform, and affection to performance of an engine due to engine oil pressure fluctuation of a main oil passage of the engine is avoided.
Description
Technical field
The utility model relates to the engine cooling technical field, is specifically related to a kind of piston cooling nozzle.
Background technique
Along with the power of motor is increasing, need cool off piston crown.At present, the cooling jet on most of motors is a ball-valve type, and such cooling jet is when opening, because the pressure valve of cooling jet is spherical, the power that causes acting on the cooling jet changes, so be easy to cause the fluctuation of engine oil pressure, influences the performance of motor.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of active force uniform piston cooling nozzle.
According to the piston cooling nozzle that the utility model proposes, comprise nozzle body and nozzle plug, the oil discharge passage that described nozzle plug has oil inlet passage and is communicated with the nozzle pipe of nozzle body, key is that described oil discharge passage and oil inlet passage joint form circular step, be provided with the plunger that is leaned by spring in the oil discharge passage, the shape of described plunger and oil discharge passage is adaptive and lean on described circular step.
Piston cooling nozzle of the present utility model, be fixed on the engine cylinder-body, the oil inlet passage of nozzle plug is communicated with the engine cylinder-body main oil gallery, when motor output was more high-power, the engine oil pressure of the oil inlet passage of nozzle plug increased, and the pressure that acts on the plunger increases, thereby pressure spring, plunger moves, this moment oil inlet passage and oil discharge passage conducting, and machine oil sprays from nozzle pipe.Piston cooling nozzle of the present utility model is by the oil discharge passage adaptive plunger of employing with piston cooling nozzle, during work, engine oil pressure is to act on the flat end face of plunger, the power that has guaranteed to act on the cooling jet is uniform, improved the problem that traditional spherical valve causes the engine oil pressure fluctuation easily, reduced the influence of piston cooling nozzle engine performance.
Described plunger is provided with and can supplies the deep cavity of described spring, and spring just can be firm by the cavity of plunger like this, guarantees that spring leans the stability of plunger.
Described plunger has the supporting portion of going deep in the described spring.Plunger also can be arranged to the T type, just can guarantee that by the supporting portion of going deep in the spring spring leans the stability of plunger.
The side of described nozzle body is provided with some locating faces that can cooperate with engine cylinder-body.Nozzle body is by being provided with some locating faces in its side, cooperate with the respective bump on the engine cylinder-body, just can position, guarantee the accuracy of nozzle pipe eject position, compare former bolt or locating stud location and can save cost and reduce installation procedure the nozzle body body.
The other end of described spring is by a base support, and described base has the supporting portion of going deep in the described spring, further guarantees the stability of spring.
Described nozzle plug is fixedlyed connected with engine cylinder-body by screw thread, and the bottom of nozzle plug is the shade shape and cooperates with the end face seal of nozzle body.Screw thread is set on the nozzle plug, nozzle body is had good positioning, the end face that again nozzle plug precession engine cylinder-body to the bottom of its shade shape is compressed nozzle plug gets final product, the convenient installation.
Piston cooling nozzle of the present utility model, change plunger into by ball valve with traditional piston cooling nozzle, the active force that has guaranteed to act on the piston cooling nozzle is uniform, avoids causing the engine oil pressure fluctuation of motor main oil gallery and causing influencing engine performance.
Description of drawings
Above-mentioned and otherwise advantage of the present utility model is from obviously and easily understanding becoming embodiment's the description below in conjunction with accompanying drawing, wherein:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the mounting structure schematic representation of the utility model and engine cylinder-body;
Fig. 3 analyses and observe mechanism's enlarged view for the A-A of Fig. 2.
Embodiment
Describe embodiment of the present utility model below in detail.
As Fig. 1,2,3,4, piston cooling nozzle of the present utility model, comprise nozzle body 1 and nozzle plug 2, the oil discharge passage 22 that nozzle plug 2 has oil inlet passage 21 and is communicated with the nozzle pipe 11 of nozzle body 1, oil discharge passage 22 forms circular step 23 with oil inlet passage 21 joints, be provided with the plunger 4 that is leaned by spring 3 in the oil discharge passage 22, plunger 4 is adaptive and lean on circular step 23 with the shape of oil discharge passage 22.But plunger 4 is provided with the deep cavity 41 of ammunition feed spring 3.The side of nozzle body 1 is provided with the locating face 12 and 13 that can cooperate with engine cylinder-body.The other end of spring 3 is supported by a base 5, and base 5 has the supporting portion of going deep in the spring 3 51.Nozzle plug 2 is fixedlyed connected with engine cylinder-body 6 by screw thread, and the bottom of nozzle plug 2 is the shade shape and cooperates with the end face seal of nozzle body 1.
Working principle of the present utility model is as follows:
When motor do not work or output power hour, the engine oil pressure of the oil inlet passage 21 of nozzle plug 2 is less, the pressure that acts on the plunger 4 is less, and plunger 4 leans circular step 23 under the effect of spring 3, and oil inlet passage 21 and oil discharge passage 22 joints are closed condition; When motor output was more high-power, the engine oil pressure of the oil inlet passage 21 of nozzle plug 2 increased, and the pressure that acts on the plunger 4 increases, thus pressure spring 3, plunger 4 moves, this moment oil inlet passage 21 and oil discharge passage 22 conductings, and machine oil is from nozzle pipe 11 ejections.
Piston cooling nozzle of the present utility model, change plunger into by ball valve with traditional piston cooling nozzle, the active force that has guaranteed to act on the piston cooling nozzle is uniform, avoids causing the engine oil pressure fluctuation of motor main oil gallery and causing influencing engine performance.
