Description
Technical field
The utility model is related to cylinder field, more particularly to a kind of fuel-economizing cylinder.
Background technology
Cylinder is the cylindrical metal parts for guiding piston that straight reciprocating motion is carried out in cylinder jacket.Air is in engine
Mechanical energy is converted heat into by expansion in cylinder jacket；Gas receiving piston in compresser cylinder compresses and improves pressure.
Inwall generally in cylinder jacket can coat lubricating oil to make the motion of piston more smooth, less capacity loss and
Reduce abrasion.Notification number discloses a kind of air cylinder sleeve of engine for improving greasy property for the Chinese patent of 202659364U,
Including cylinder sleeve body, it is provided with cylinder sleeve body inner surface correspondence piston B.D.C position and is made up of multiple densely covered and not connected holes
Oil storage bring raising greasy property.However, because the fuel-displaced lubricating oil with Hole is in saturation state all the time, in piston
Motion process in, the lubricating oil of piston institute adhesive tape store in hole with cannot being moved into for piston, therefore, lubricating oil
Or the waste of lubricating oil can be caused with the moving region of the disengaging piston for moving each time bit by bit of piston.
Utility model content
The purpose of this utility model is to provide a kind of fuel-economizing cylinder, and it can constantly be stored in the motion process of piston
With release lubricating oil, and then reduce lubricating oil loss.
Above-mentioned technical purpose of the present utility model technical scheme is that：
A kind of fuel-economizing cylinder, including cylinder jacket, piston rod and piston, the cylinder liner internal wall is along its axially uniform some storage
Oily band, the fuel-displaced band includes that some circumferences are distributed on the oil storage tank of cylinder liner internal wall, the oil storage tank along cylinder jacket axial direction
Set, and the oil storage tank length less than the length on piston axis direction.
By such scheme, when piston is displaced outwardly from the end cap of cylinder jacket, piston can glue it from cylinder jacket
The lubricating oil of band is pushed out, and when piston is by oil storage tank, unnecessary lubricating oil will be entered into oil storage tank on piston, kept away
Exempt from the active strokes scope that a large amount of lubricating oil pushed away from piston, cause the loss of substantial amounts of lubricating oil.And work as piston and leave this
During oil storage tank, the lubricating oil in oil storage tank can slowly flow from oil storage tank to from outside oil storage tank, the shape on cylinder liner internal wall
Into oil film, lubricating condition good between piston and cylinder jacket is given in piston return.The length for going out oil groove is less than piston shaft
Upward length, from regardless of whether piston is in out that position of oil groove, all without because the presence of oil storage tank allows piston both sides
Connection, it is ensured that the air-tightness of cylinder.
Further, the oil storage tank is in waist type, and the notch of the oil storage tank is provided with fillet.
By such scheme, piston ring will not be abraded during up and down motion by the edge of oil storage tank, while also avoiding
The pulling and scuffing of cylinder bore of cylinder jacket.
Further, the groove width of the oil storage tank is 0.1-0.5mm.
By such scheme, oil storage tank can possess good fuel-displaced ability, while lubricating oil also can be from oil storage tank
Outflow, realizes the storage and release of lubricating oil.
Further, along the circumferential uniform some oil storage holes of cylinder jacket between the adjacent oil storage band.
By such scheme, the oil of oil storage hole is in saturation state all the time, in the reciprocatory movement of piston, in piston
Surface forms oil film, and the surface to piston is lubricated, and further reduces the friction between piston and cylinder jacket.
Further, a diameter of 0.05-0.1mm of the oil storage hole.
By such scheme, oil storage bore dia is smaller, and impurity will not be entered in hole and carbon distribution, and the lubricating oil in it is produced
Outflow is difficult, saturation state can be all the time in such that it is able to which long-term lubrication is carried out to piston face.
Further, the aperture of the oil storage hole is provided with deep gouge.
By such scheme, the setting of deep gouge can allow the lubricating oil of piston face to enter into lubricating oil and form thicker
Oil film, and the lubricating oil in oil storage hole has the effect of tension force to the oil film in deep gouge, so as to ensure that the length of oil film in deep gouge
Phase is present, and strengthens lubricant effect.
Further, a diameter of 0.2-0.4mm of the deep gouge.
By such scheme, the diameter of deep gouge ensure that oil film has enough to cylinder liner internal wall between 0.2-0.4mm
Adhesive force.
In sum, the utility model has the advantages that：
1st, the oil storage band that cylinder liner internal wall is provided with some oil storage tanks compositions carries out the storage and release of lubricating oil, allows
It forms oil film in cylinder liner internal wall, and lubricious strip good between piston and cylinder jacket is given during piston back-and-forth movement
Part, while can also reduce the loss of lubricating oil；
2nd, the setting oil storage hole between oil storage band, the lubricating oil in it is in saturation state all the time, in the reciprocal fortune of piston
During dynamic, oil film is formed in piston face, the surface to piston is lubricated, further reduced between piston and cylinder jacket
Friction.
