Abstract

The utility model relates to a piston, in particular to a lubricating groove type piston. The lubricating groove type piston comprises a piston and an oil ring, wherein an oil ring is arranged on the upper portion of the piston; and a lubricating groove is formed on the skirt portion of the piston and communicated with the oil ring through a groove. By using the piston, lubricating oil in the lubricating groove can be applied to thoroughly lubricating the friction parts of the piston with the inner wall of a cylinder; therefore, the efficiency of an engine is improved; the fault rate is reduced; and the cost is saved.

Description

Lubricated slot type piston
Technical field
The utility model relates to a kind of piston, especially a kind of lubricated slot type piston.
Background technique
Former piston face and cylinder inner wall friction can produce high heat, piston easy deformation in this environment, and the skirt section produces expands, and occurs pull-cylinder phenomena easily, reduces the power of motor.
The model utility content
In order to overcome the deficiency of piston and cylinder friction part poor lubrication, the utility model provides a kind of lubricated slot type piston.
The utility model solves the technological scheme that its technical problem adopted: a kind of lubricated slot type piston, comprise piston and oil ring, and piston top is provided with oil ring, and the piston skirt is provided with lubrication groove, and lubrication groove is communicated with oil ring is fluted.
The beneficial effect of the utility model is: use this piston can utilize the lubricant oil in the lubrication groove, the friction position of piston and cylinder inner wall is carried out lubricating fully, improve the efficient of motor, reduce rate of fault, practiced thrift cost.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the schematic representation of the utility model;
1. pistons among the figure, 2. oil ring, 3. lubrication groove.
Embodiment
Combine accompanying drawing that the utility model is done further detailed explanation now.These accompanying drawings are the schematic representation of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Like Fig. 1 is the structural representation of the utility model, and a kind of lubricated slot type piston comprises piston 1 and oil ring 2, and piston 1 top is provided with oil ring 2, and piston 1 skirt section is provided with lubrication groove 3, lubrication groove 3 and 2 fluted connections of oil ring.
During work, the lubricant oil in oil ring 2 grooves can enter in the lubrication groove 3 via connectivity slot, when piston 1 moves back and forth in cylinder; Lubricant oil on the lubrication groove just can be lubricated the contact position of piston 1 with cylinder; Use this piston can utilize the lubricant oil in the lubrication groove, the friction position of piston and cylinder inner wall is carried out lubricating fully, improve the efficient of motor; Reduce rate of fault, practiced thrift cost.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
