Abstract
The utility model relates to the technical field of engines, in particular to a cooling nozzle of an engine piston. The cooling nozzle of the engine piston comprises a main oil supply pipe, a plurality of cooling spraying pipes and positioning pin bases. A transition oil pipe is arranged between each cooling spraying pipe and the main oil supply pipe. The positioning pin bases are arranged between the cooling spraying pipes and the transition oil pipes and respectively connected with the cooling spraying pipes and the transition oil pipes. The other end of each transition oil pipe is connected with the main oil supply pipe. The axes of the cooling spraying pipes and the axes of the transition oil pipes are all plane curves. According to the cooling nozzle of the engine piston, traditional cooling spraying pipes are divided into the transition oil pipes at the rear sections and the cooling spraying pipes at the front sections, the axes of the cooling spraying pipes and the axes of the transition oil pipes are all the simple plane curves, the moving directions of pipelines of the cooling spraying pipes are simple, the spraying positions are accurate in positioning, and the cooling effect of the piston is ensured. Meanwhile, by the adoption of the structural design, the positioning accuracy of the cooling nozzle can be ensured, the structure of a cylinder body can also not be changed, the generality of the cylinder body is ensured to the maximum extent, and the cost is saved.
Description
Technical field
The utility model relates to technical field of engines, is specifically related to a kind of engine piston cooling nozzle.
Background technique
Along with continually strengthening of motor, the heat load of piston is more and more higher, and the engine piston of high load generally adopts the inner-cooling oil recess design, and cooling machine oil sprays into cooling oil chamber by nozzle, flow out after shock absorption piston heat in oil pocket, thereby reduce piston temperature.Cooling jet is generally the cooling unit that is fixed on engine body, when piston is done the high speed to-and-fro motion, cooling machine oil is sprayed in inner-cooling oil recess.
The structure of traditional engine piston cooling nozzle as shown in Figure 1, comprise main fuel supply line 3, be connected to several cooling spray pipes 2 on main fuel supply line 3 and be arranged on location key seat 1 on cooling spray pipe 2, wherein, the spatial structure form of cooling spray pipe 2 is very complicated, its nozzle axis is space curve, shortcoming is that manufacturing complexity and precision are difficult for guaranteeing, can cause the eject position low precision of cold oil, thereby affect the cooling effect of piston.
The model utility content
The purpose of this utility model is to provide a kind of engine piston cooling nozzle, solves above technical problem.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of engine piston cooling nozzle, comprise main fuel supply line, several cooling spray pipes and location key seat, it is characterized in that: be provided with a transition oil pipe between described each cooling spray pipe and main fuel supply line; Described location key seat is located between cooling spray pipe and transition oil pipe, and is connected with cooling spray pipe, transition oil pipe respectively; The other end of described transition oil pipe is connected with main fuel supply line.
Say further, the axis of described cooling spray pipe is plane curve.
Furtherly, the axis of described transition oil pipe is plane curve.
Beneficial effect: compared with prior art, the utility model has been divided into two sections with traditional cooling spray pipe, and back segment is the transition oil pipe, and its two ends connect respectively location key seat, main fuel supply line, and axis is the simple flat surface curve; Leading portion is cooling spray pipe, and it is connected with location key seat, and axis is also plane curve, and the pipeline trend is simple, and the eject position accurate positioning, has guaranteed the cooling effect of piston.And, adopt the said structure design, can guarantee the positioning precision of cooling jet, also can revise housing structure, farthest guarantee the general of cylinder body, save cost.
