Specific embodiment
It elaborates below to the embodiments of the present invention, the present embodiment before being with technical solutions of the utility model
It puts and is implemented, the detailed implementation method and specific operation process are given, but the protection scope of the utility model is unlimited
In following embodiments.
As shown in Figure 1-3, a kind of pressure control type piston cooling spray nozzle structure of the present embodiment, including cooling nozzles body 1, spray
Oil pipe 2, pressure control device 3 are perforative channel inside cooling nozzles body 1, and spray bar 2 is mounted on the side of cooling nozzles body 1
Face, spray bar 2 are communicated with cooling nozzles body 1, constitute oil passageway, it is cold that pressure control device 3 is capable of being mounted on for adjusting position
But the spray bar 2 in nozzle body 1 communicates place with cooling nozzles body 3.The utility model enables to oil injection amount with pressure
When raising, cracking pressure control device 3 and increase oil level, oil injection amount with pressure reduction when, close pressure control dress
3 are set to reduce oil level.
In the present embodiment, the cooling nozzles body 1 be it is columnar structured, inner passage include the big first passage of internal diameter,
Step-like structure is constituted at the small second channel of internal diameter, first passage and second channel, spray bar 2 is connected to the bottom of first passage
Portion, pressure control device 3 are mounted at first passage, and can block spray bar 2.
In the present embodiment, the pressure control device 3 includes spring base 31, spring 32, solid steel ball 33, solid steel ball 33
The bottom for being connected to first passage, spring base 31 is mounted on the top of cooling nozzles body 1, and spring 32 is compressed to be mounted on bullet
Between spring abutment 31 and solid steel ball 33, spring 32 is compressed state in itself, but decrement is not easy excessive, not so engine oil pressure
Bigger it need to could open spray bar 2 and the direct channel of cooling nozzles body 3.
In addition to this it is possible to which a solid steel ball identical with the internal diameter of spray bar 2 directly to be got lodged in the end of spray bar 2
Portion is connected to the side in solid steel ball and cooling nozzles body 1, the i.e. vertical cooling nozzles body of spring connection solid steel ball by spring
1, it is equipped with chock plug in one end of cooling nozzles body 1, it is identical as the present embodiment principle；It can be adjusted according to engine oil pressure size
