Abstract
The utility model relates to an internal combustion engine piston, in particular to a novel piston. The outer wall of the novel piston is provided with a lubrication groove. An inner cavity of the piston is hollow. The novel piston is characterized in that the position on the outer wall of the piston, which is positioned inside the lubrication groove, is provided with lubricating holes; and the diameter of the lubricating holes is gradually decreased front outside to inside. The utility model has ingenious and simple structure, is suitable for wide popularization and application, has obvious effect and basically does not increase the existing cost.
Description
Technical field
The utility model relates to internal combustion engine, particularly a kind of novel piston.
Background technique
Internal combustion engine and cylinder body are realized lubricated and cooling by lubricant oil, but internal combustion engine and cylinder body fit are tight, lubricant oil can only be in the of short duration lubricated and cooling of to-and-fro motion, a kind of way of slotting at piston outer wall has been arranged to realize sufficient lubrication and cooling degree at present, but piston outer wall still have can not abundant contact lubricated oil the position, its cooling and lubrication problem have to be solved.
Summary of the invention
The utility model provides a kind of novel piston simple in structure, that efficiently lubricate and lower the temperature at above technical problem just.
The purpose of this utility model realizes by following technical proposal:
A kind of novel piston, its outer wall is provided with oil groove, and piston cavity hollow is characterized in that: the position of piston outer wall between oil groove is provided with oilhole, and oilhole dwindles gradually from its diameter outside to inside.
In pistons work, though piston circular arc outer wall contacts with cylinder body by its oilhole, lubricant oil can enter the lubricated and protection that realizes between piston and the cylinder body motor through the piston cavity of hollow.Oilhole can help improving lubricated efficient from the diminishing structure of its diameter outside to inside, particularly when piston withdraws from, and in the suitable enhanced leaktightness effect of the pressure of the stage of Piston Compression lubricant oil.
Structure of the present utility model is ingenious and simple, is suitable for extensively promoting and utilization, and the utility model effect does not obviously increase existing cost substantially.
Description of drawings
Fig. 1 is a cross-sectional view of the present utility model.
Wherein, 1---piston outer wall, 2---oil groove, 3---oilhole.
Embodiment
The utility model is described in further detail below in conjunction with specific embodiment and Figure of description.
By following examples the utility model is described for example further, and limit the utility model never in any form, under the prerequisite that does not deviate from technical solution of the present utility model, any change or change that those of ordinary skills that model utility is done realize easily all fall within the claim scope of the present invention.
A kind of novel piston, its outer wall is provided with oil groove, piston cavity hollow, the position of piston outer wall between oil groove is provided with oilhole, and oilhole dwindles gradually from its diameter outside to inside.
In pistons work, though piston circular arc outer wall contacts with cylinder body by its oilhole, lubricant oil can enter the lubricated and protection that realizes between piston and the cylinder body motor through the piston cavity of hollow.Oilhole can help improving lubricated efficient from the diminishing structure of its diameter outside to inside, particularly when piston withdraws from, and in the suitable enhanced leaktightness effect of the pressure of the stage of Piston Compression lubricant oil.
