Abstract
The utility model relates to a piston cooling nozzle assembly which comprises two oil spraying pipes. The two oil spraying pipes are respectively fixed on two sides of a metal ring and communicated with the metal ring, an oil inlet channel is arranged in a bolt, a valve plug is arranged in the bolt, a spring supports against the valve plug, a limited block supports against the spring, the bolt is sleeved into the metal ring, an oil inlet hole in the metal ring is aligned to an oil outlet hole in the bolt, two oil spraying branch pipes are respectively fixedly arranged on the two oil spraying pipes, and the oil spraying branch pipes are communicated with the oil spraying pipes. The oil inlet channel of the bolt is communicated with a main oil channel of an engine cylinder body, when an engine outputs higher power, pressure of engine oil in the oil inlet channel is increased, and pressure acting on the valve plug is increased, and thus the spring is compressed, the valve plug moves, and the engine oil flows into the oil outlet hole from the oil inlet hole, is sprayed from the oil spraying pipes to the oil spraying branch pipes, and respectively acts on a self-repaired piston cooling nozzle. The piston cooling nozzle assembly has a reasonable structure, and ensures the applied force on the piston cooling nozzle is uniform.
Description
Technical field
The utility model relates to motor car engine cooling technology field, refers in particular to a kind of piston cooling nozzle assembly.
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.Chinese patent once disclosed a kind of " diesel engine piston assembly of cooling jet " (China, notification number CN2584845Y, November 5 2003 day for announcing), and it has nozzle body, offers oil duct in the nozzle body, and spherical valve core is fitted on the oil duct through compression-spring device.Its usefulness be ball valve.Chinese patent once disclosed " a kind of piston cooling nozzle " (China; Notification number CN201786432U, April 6 2011 day for announcing), its structure comprises nozzle body and nozzle plug; The oil discharge passage that nozzle plug has oil inlet passage and is communicated with the nozzle pipe of nozzle body; Oil discharge passage and oil inlet passage joint form circular step, are provided with the plunger that is leaned by spring in the oil discharge passage, the shape adaptation of plunger and oil discharge passage and leaning on circular step.It is that ball valve with traditional piston cooling nozzle changes plunger into.
Summary of the invention
The purpose of the utility model is to provide a kind of piston cooling nozzle assembly, and it is rational in infrastructure, and the active force of guarantee effect on piston cooling nozzle is uniform.
For achieving the above object, the solution that the utility model is taked is: a kind of piston cooling nozzle assembly, and it comprises spray bar; Article two, spray bar is separately fixed at the both sides of metal ring and is communicated with metal ring, has oil inlet passage in the bolt, and spool is placed in the bolt; Spring withstands spool, and limiting stopper withstands spring, and bolt is inserted in metal ring; Oil inlet hole is aimed at the oil outlet in the bolt in the metal ring, is fixed with two oil spout arms on two spray bars respectively, and the oil spout arm is communicated with spray bar.
The oil inlet passage of bolt is communicated with the engine cylinder-body main oil gallery, and when motor output was more high-power, the engine oil pressure in the oil inlet passage increased; The pressure that acts on the spool increases; Thereby pressure spring, spool moves, and this moment, machine oil was from the oil inlet hole to the oil outlet; Ejection acts on respectively and reviews one's lessons by oneself on the piston cooling nozzle from spray bar to the oil spout arm.It is rational in infrastructure, and the active force of guarantee effect on piston cooling nozzle is uniform.
