Summary of the invention
The object of the present invention is to provide a kind of simple and reasonable band valve piston cooling jet assembly, this band valve piston cooling jet assembly completes spring seat and nozzle body is assembled and after flange process, flange and spring seat are welded, play real fastening effect, ensure motor operational reliability, when avoiding spring seat and nozzle body Spielpassung, flanging process fastening spring seat can not guarantee that spring seat is fastening, cause engine oil pressure that spring seat is come off, there is pressure release in nozzle assembly spring seat place, causes piston can not cool in time, lubricate and significant trouble occurs.
For achieving the above object, the invention provides a kind of band valve piston cooling jet assembly, this band valve piston cooling jet assembly comprises: nozzle body, and it comprises: spray bar and body, one end of described spray bar be fixed on this body periphery and with the inner space of body; The periphery of described body is up big and down small stepped, and the inner chamber of described body is also up big and down small stepped, and lower end loculus is oil inlet hole, for communicating with engine cylinder-body main oil gallery; Nozzle flange, it is inserted in the small end of the stepped perimeter body of described nozzle body and welds fastening; Steel ball, it is arranged at the large chamber, upper end of the tube cavity of described nozzle body; Spring, steel ball is withstood in its one end; And spring seat, it is located at the top of the body of described nozzle body and is welded and fixed by flange lid, to withstand the other end of described spring.
Preferably, in technique scheme, spray bar is bent into 90 degree.
Preferably, in technique scheme, spring seat is located at the top of the body of described nozzle body and carries out laser bonding and fix by flange lid.
Preferably, in technique scheme, one end of spray bar is weldingly fixed on the periphery of this body.
Compared with prior art, the present invention has following beneficial effect: this band valve piston cooling jet assembly completes spring seat and nozzle body is assembled and after flange process, flange and spring seat are welded, play real fastening effect, ensure motor operational reliability, when avoiding spring seat and nozzle body Spielpassung, flanging process fastening spring seat can not guarantee that spring seat is fastening, cause engine oil pressure that spring seat is come off, there is pressure release in nozzle assembly spring seat place, causes piston can not cool in time, lubricate and significant trouble occurs.
Accompanying drawing explanation
Fig. 1 is that the spring seat of existing band valve piston cooling jet assembly and nozzle body assemble turnup structure schematic diagram.
Fig. 2 is the structural representation of band valve piston cooling jet assembly of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole specification and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or constituent element, and do not get rid of other element or other constituent element.
As shown in Figure 2, concrete structure according to the band valve piston cooling jet assembly of the specific embodiment of the invention comprises: spring seat 1, spring 2, nozzle body 3, steel ball 4 and nozzle flange 5, wherein nozzle body 3 comprises a bending spray bar and the body with through hole, and spray bar one end is fixed on the periphery of body and is communicated with tube cavity.Nozzle flange 5 is inserted in the small end of nozzle body 3 and is welded fastening, steel ball 4 is put into the inner chamber of nozzle body body and is terminated in oil inlet hole, spring 2 withstands steel ball 4 (spool), and spring 2 is withstood on the top that spring seat 1 is located at nozzle body body by flange and welding procedure lid.Nozzle assembly oil inlet passage communicates with engine cylinder-body main oil gallery, when after engine start, power increase makes engine oil pressure increase, oil pressure acts on the pressure increase on steel ball spool, thus Compress Spring, spool moves, and now machine oil is from oil inlet hole to oil outlet, from spray bar ejection lubrication piston, ensure the normal operation of motor.This band valve piston cooling jet assembly completes spring seat and nozzle body is assembled and after flange process, flange and spring seat are welded, and plays real fastening effect, ensures motor operational reliability.
