The model utility content
The purpose of the utility model is to provide that a kind of energy loss is little, noise is little, the engine piston cooling jet of long service life; The further purpose of the utility model be to provide a kind of jet pipe setting angle accurately, the nozzle high engine piston cooling jet of some positional accuracy of practicing shooting.
To achieve these goals, the technological scheme of the utility model employing is:
Described engine piston cooling jet comprises nozzle body, on the said nozzle body cavity is set, and an end and the nut of said cavity are tightly connected, and the other end is provided with oil duct; Be provided with steel ball and spring in the inside of said cavity, a side of said steel ball is stuck on the oil duct of cavity, and said spring is located between nut and the steel ball; On said nozzle body, be provided with two jet pipes that are communicated with said cavity; Said cavity is cross structure.
Said inside cavity is provided with smooth round-corner transition structure.
Said nozzle body is provided with the jet pipe that is sintered into one with nozzle body.
On the oil duct of said cavity, be provided with seal ring.
Said nozzle body is provided with locating stud and bolt mounting holes.
The advantage of the utility model is: described engine piston cooling jet, be set to cross structure through said cavity, and the volume of cavity increases, and inside cavity is provided with smooth round-corner transition structure simultaneously; Can effectively reduce the resistance of engine oil flow, make machine oil to spray more uniformly, reduce the turbulent flow that produces when machine oil sprays rapidly, reduce energy loss; The flow velocity of machine oil in cavity reduces simultaneously, and the vibration noise that produces between machine oil and steel ball also decreases than traditional piston cooling nozzle; The wearing and tearing of cavity also reduce greatly, the working life that can improve said piston cooling nozzle.Described engine piston cooling jet is installed on the engine cylinder-body through bolt and locating stud, and the setting angle of jet pipe is accurate, nozzle is practiced shooting, and the some positional accuracy is high.

Embodiment
Contrast accompanying drawing below,, the embodiment of the utility model is done further detailed explanation through description to optimum embodiment.
To shown in Figure 4, described engine piston cooling jet comprises nozzle body 1, and cavity 9 is set on the nozzle body 1 like Fig. 1, and an end and the nut 2 of cavity 9 are tightly connected, and the other end is provided with oil duct 10; Be provided with steel ball 8 and spring 7 in the inside of cavity 9, a side of steel ball 8 is stuck on the oil duct 10 of cavity 9, and spring 7 is located between nut 2 and the steel ball 8; On nozzle body 1, be provided with two jet pipes 3 that are communicated with cavity 9; Cavity 9 is cross structure.
Cross through cavity 9 is designed to, cavity 9 inside are provided with smooth round-corner transition structure, compare with traditional ball-valve type piston cooling nozzle, and this cavity 9 volumes increase; Being provided with steel ball 8 in the cavity 9 links to each other with cross cavity 9 with spring 7, two jet pipes 3; When machine oil got in the cavity 9 through oil duct 10, the pressure effect of machine oil promoted the oil duct 10 of steel ball 8 away from cavity 9, and when machine oil got into cavity 9 inside fully, steel ball 8 was fitted with the oil duct 10 of cavity 9, and machine oil ejects through jet pipe 3 then; After the oil injection, cavity 9 internal pressures reduce, and outside machine oil is pushed steel ball 8 again open and got into cavity 9 inside then, and when machine oil got into cavity 9 inside fully, steel ball 8 was fitted with the oil duct 10 of cavity 9, and machine oil ejects through jet pipe 3 then; So back and forth can realize the control of cavity 9 pressure inside, cavity volume increases, and can effectively reduce the resistance of engine oil flow, makes machine oil to spray more uniformly, has reduced the turbulent flow that produces when machine oil sprays rapidly, reduces energy loss; Cavity 9 volumes increase simultaneously; The flow velocity of machine oil in cavity 9 reduces; The vibration noise of 8 generations of machine oil and steel ball is compared with traditional piston cooling nozzle and is decreased, and the wearing and tearing of cavity 9 also reduce greatly, the working life that can improve said piston cooling nozzle.Such engine piston cooling jet is less demanding to the machine oil turbidity test, can reduce cost.
