Abstract
The utility model discloses a piston cooling nozzle assemble of a diesel engine, which is provided with a nozzle body in which an oil passage is arranged; a spherical valve core is pressed and assembled on the oil passage by a pressure spring device. The utility model has the advantages of reasonable structure, which can be used for regulating oil injection conditions with operation conditions of the diesel engine; the contact sealing performance of the spherical valve core and the oil duct is good.
Description
Technical field:
The utility model relates to a kind of diesel engine cooling jet.
Background technique:
Existing diesel engine piston cooling jet generally is not provided with the control spool on its oil duct, no matter when piston high speed operation or low cruise, all spray cold oil, and unnecessary oil spout when the piston low cruise causes waste.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and can regulate the diesel engine piston assembly of cooling jet of fuel injection condition with the diesel engine motion speed.
Technical solution of the present utility model is:
A kind of diesel engine piston assembly of cooling jet has nozzle body, offers oil duct in the nozzle body, its feature; Spherical valve core is fitted on the oil duct by compression-spring device.
Compression-spring device comprises stage clip, and stage clip is connected with the spool connecting body, and the spool connecting body links to each other with spherical valve core.
The utility model is rational in infrastructure, can regulate fuel injection condition with the diesel engine operation conditions, spherical valve core and oil duct to contact adaptation good.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing is an embodiment's of the utility model a configuration diagram.
A kind of diesel engine piston assembly of cooling jet has nozzle body, offers oil duct 2 in the nozzle body, spherical valve core 3 is fitted on the oil duct 2 by compression-spring device, compression-spring device comprises stage clip 4, and stage clip 4 is connected with spool connecting body 5, and spool connecting body 5 links to each other with spherical valve core 3.Nozzle body is made up of with the track bolt 6 that is connected with part 1 part 1 that is provided with spout.
