Description
Technical field
The invention belongs to engine arts, and in particular to a kind of integrated morphology of rebreather of engine.
Background technology
Respirator is mounted in the functional component on diesel-engine body, is typically mounted on cavaera housing, its effect
It is that Oil-gas Separation is carried out to the gas blowby of crankcase, so that the oil droplet separated is fallen back in crankcase, make the cleaning gas after separation
Body is introduced into gas handling system and participates in burning, plays the role of dropping low exhaust gas emission, reduces consumption of lubricating oil.
The integration mode of respirator and cavaera housing has welded type, screw thread installing type, bolt installing type etc..Welded type is
Welding structure is designed on respirator, is welded on valve-chamber cover cover body, and the two is combined as a whole；This integrated side
Formula is most commonly seen.Screw thread installing type is to be assembled to respirator on valve-chamber cover cover body by helicitic texture, such as referenced patent
CN201220576368.Bolt installing type is to design the mounting ear structure with mounting hole on respirator, will by bolt
Respirator is fixed on cavaera housing, such as referenced patent CN201420086861, CN201420550018.
Prior art disadvantage：
The respirator integration mode of welded type, needs to design welding structure on respirator, by welding procedure by its
It is welded on valve-chamber cover cover body, the two is combined as a whole；On the one hand it needs to use special welding equipment and tooling, it is another
Respirator gas outlet orientation after aspect welding is i.e. determining and unique；If it is intended to obtaining the gas outlet of different direction, weight is needed
New adjustment welding tooling or respiratory organ structure, carry out custom design and the production of the respirator in different gas outlet orientation.
The mounted respirator integration mode of screw thread, such as a kind of novel overhead respirators of referenced patent CN201220576368
Device, respirator are integrated by plug screw seat with cylinder head cover；Plug screw seat upper end is fixed on respirator lower part, and plug screw seat lower end passes through spiral shell
The leakproofness that line is connected on cylinder head cover and washer need to be used to ensure connection；The upper body of respirator passes through screw and wing nut
Be fixed on respirator lower body, therebetween be equipped with sealing ring ensure sealing, wing nut can be unscrewed to respirator upper body into
Row rotation, the orientation for adjusting gas outlet.The adjustment in respirator gas outlet orientation may be implemented in this integration mode, but structure is multiple
Position that is miscellaneous, need to sealing is more, and adjustment is inconvenient, easily leaks.
The mounted respirator integration mode of bolt, a kind of such as respirators of referenced patent CN201420086861 and starts
Machine, respirator are equipped with mounting ear, realize that the assembly of respirator and other components is integrated；Such as referenced patent CN201420550018
A kind of valve cage the cover of plug-in respirator room, plug-in respirator room pass through three bolts assemblies to valve cage the cover outer wall.This
Kind of integration mode, needs to carry out that assembly is integrated using bolt, and it is integrated after respirator gas outlet orientation determine and unique.Such as
Fruit is wanted to obtain the gas outlet of different direction, needs the structure for adjusting respirator, carries out the respirator in different gas outlet orientation
Custom design and production.
Invention content
Present invention seek to address that the above problem, provides a kind of integrated morphology of rebreather of engine, its simple installation, side
Position is adjustable, flexible and adaptable；Reduce number of parts, it is not necessary to use welding manner or screw bolt, simplify integrated work
Skill reduces production cost.Respirator is fabricated separately, detects, quality management and control as individual sub-unit part；And it can make
It is promoted the use of for general part.The radial seal between respirator and valve-chamber cover cover body is realized using oil sealing；Use card
Buckle structure realizes the axial limiting of respirator；The rotational positioning of respirator is realized using retaining structure；The such of respirator integrates
Mode can be assembled and rotated according to the requirement in gas outlet orientation, is realized freely adjusting for respirator gas outlet orientation, is made hair
Motivation is more flexible when matching different automobile types space and adaptability, the technical solution used are as follows：
A kind of integrated morphology of rebreather of engine, which is characterized in that including:Respirator, valve-chamber cover cover body and bone
The bottom of frame oil sealing, the respirator is formed with buckle and screens, and the valve-chamber cover cover body has mounting hole, the buckle
Bottom extend outward to form clamping portion along the radial direction of respirator, there is card slot on the valve-chamber cover cover body, it is described
Card slot is made of several slot unit continuitys, and the slot unit is zigzag, and shape and the slot unit of the screens match,
The respirator is installed on valve-chamber cover cover body, and the buckle penetrates in the mounting hole of valve-chamber cover cover body, clamping portion
With the bottom surface clasp joint of mounting hole；The outside framework oil seal makes respirator and valve between respirator and valve-chamber cover cover body
Radial seal between chamber cap cover body；The screens penetrates in card slot, the card slot and respirator concentric.
On the basis of above-mentioned technical proposal, the bottom surface of the mounting hole is finish-machined to one and the matched axial limit in clamping portion
Plane.
On the basis of above-mentioned technical proposal, the buckle is 6, and the screens is 2, and the buckle and screens are around exhaling
The axis of haustorium is uniformly distributed.
Beneficial effects of the present invention are：Simple installation, orientation are adjustable, flexible and adaptable；Reduce number of parts, no
Welding manner or screw bolt must be used, integrated technique is simplified, reduces production cost.Respirator is as individual sub-unit
Part is fabricated separately, detects, quality management and control；And it can be promoted the use of as general part.Using oil sealing realize respirator with
Radial seal between valve-chamber cover cover body；The axial limiting of respirator is realized using buckle structure；Use retaining structure reality
The rotational positioning of existing respirator；Such integration mode of respirator can be assembled and rotated according to the requirement in gas outlet orientation,
It realizes freely adjusting for respirator gas outlet orientation, engine is made to be more flexible and adapt to when matching different automobile types space
Property.
