CN2422458Y - Twisted sealed oil-saving piston ring - Google Patents

Abstract

The utility model relates to a twisted hermetically sealed oil-saving piston ring for an internal-combustion engine, which comprises a piston ring. The utility model is characterized in that an inner step 1 is arranged on the piston ring, wherein, two open ends 2 of which are arranged into oblique sections which are mutually crossed and matched. The problems of gas leakage and oil leakage of the opening gap, the side clearance and the back clearance of the piston ring can be thoroughly solved. Cylinder pressure can be enhanced, power is increased, machine oil and fuel oil are saved by an engine adopting the piston ring, service life of the engine is prolonged, and the engine can be started easily.

Description

Twist hermetically sealed fuel-economizing piston ring

The utility model relates to the sealed piston ring that a kind of internal-combustion engine is used, the hermetically sealed fuel-economizing piston ring of particularly a kind of distortion.

The opening end that is used for the sealed piston ring of internal-combustion engine at present all adopts straight cut.This notch features, easy to wear, and because the wearing and tearing between cylinder liner and piston ring, the opened gap of piston ring can increase, and the motor gas blowby takes place, scurry oily phenomenon, cause cylinder pressure to descend, the power of motor reduces, and uses not only oil consumption of such motor, easy burn oil, Mao Lanyan, contaminated air, and also the working life of motor is short.

The purpose of this utility model is to provide a kind of can effectively avoid the direct gas blowby of piston ring gap, scurry the hermetically sealed fuel-economizing piston ring of distortion of oily phenomenon.

The utility model is achieved in that the hermetically sealed fuel-economizing piston ring of a kind of distortion, and it comprises piston ring, it is characterized in that: described piston ring is provided with interior step; Two opening ends of described piston ring are arranged to mutual cross-matched scarf.

Opening of the present utility model adopts the inclined-plane interface-crossover, has sealed the opened gap of piston ring fully, can effectively prevent opened gap, back clearance gas blowby, scurry oil; Because piston ring is provided with interior step, when twist, piston ring just become butterfly, and piston ring becomes line with cylinder and contacts like this, and lack its running-in period, good airproof performance, thus solved the sideshake gas blowby of motor; As seen, the utility model has thoroughly solved the gas blowby of piston ring gap, sideshake, back clearance and has scurried oily problem, adopts the motor of this piston ring, can improve cylinder pressure, increase power, save machine oil, fuel oil, prolong the working life of motor, and the startup of motor is easy to also.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1, the utility model embodiment's 1 structural representation;

Fig. 2, be the worm's eye view of Fig. 1;

Fig. 3, be the A-A sectional view of Fig. 1;

Fig. 4, be the B-B sectional view of Fig. 1.

Referring to above-mentioned accompanying drawing as can be known: the hermetically sealed fuel-economizing piston ring of a kind of distortion, it comprises piston ring, it is characterized in that: described piston ring is provided with interior step 1; Two opening ends 2 of described piston ring are arranged to mutual cross-matched scarf.

Claims (1)

1, the hermetically sealed fuel-economizing piston ring of a kind of distortion, it comprises piston ring, it is characterized in that: described piston ring is provided with interior step (1); Two opening ends (2) of described piston ring are arranged to mutual cross-matched scarf.
