Abstract
The utility model relates to the improvement of a piston ring which processes sealing in machinery or devices such as an internal combustion engine, a compressor, etc., which is composed of a general piston ring. The opening of the piston ring is provided with a flaky object. When the opening is prevented from leaking, the flaky object is arranged on a pressed end face of the opening; when a back clearance is prevented from leaking, the flaky object is arranged on an inner circle face of the opening; when the opening and the back clearance are simultaneously prevented from leaking, the flaky object is an integral rectangular flaky object. The utility model has the advantages of economy and utility, service life prolonging of the piston ring and sealing performance enhancement of the piston ring. The opening and the back clearance of the piston ring can be fundamentally prevented from leaking.
Description
The utility model relates to a kind of improvement that explosive motor, compressor etc. is relied on the machinery or the piston ring in the device of piston ring packing.
Piston ring is a circular ring, freely stretching when guaranteeing that piston ring closely contacts with cylinder bore wall and piston ring moves in cylinder sleeve, piston ring must have an opening, and keeps rational opened gap in cylinder sleeve, but this opened gap directly influences the sealability of piston ring.For many years, people prevent the method that gap-clearance of piston rings leakage and the back clearance that causes thus leak in research always, present already used method has axially takes mouthful, radially takes mouth, composition ring technology etc., but it is taken mouth and is and takes mouth firmly, and must guarantee the opened gap that freely stretches and possess of piston ring, the technology of Shi Yonging is difficult to overcome opening, the back clearance leakage problem of piston ring at all in the past.
The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of simple in structure, economical and practical, the working life, the sealability that improves piston ring that prolong piston ring are provided, can fundamentally prevent the piston ring that gap-clearance of piston rings and back clearance leak.
The purpose of this utility model is achieved in that by the pot type piston ring and constitutes, in gap-clearance of piston rings place one tablet is installed, make gap-clearance of piston rings form flexibility and take mouth, when preventing that opening from leaking, tablet is installed on the pressurized end face of gap-clearance of piston rings place, when the piston ring pressurized, tablet can fit tightly end face automatically and play seal action, lubricant oil in the piston ring groove can play the effect that helps the tablet sealing, thereby prevent that opening from leaking, the installation of tablet should guarantee that piston ring freely stretches; When being used to prevent that back clearance from leaking, tablet is installed on the inner headed face of gap-clearance of piston rings place, and under the back pressure effect, tablet plays the effect of sealing back clearance; When being used for preventing simultaneously that opening leakage and back clearance from leaking, tablet adopts the right angle tablet of one, is installed on the pressurized end face and inner headed face of gap-clearance of piston rings place.
The utlity model has following good effect:
1, thoroughly solves gap-clearance of piston rings leakage and back clearance leakage problem, improve the piston ring packing performance.
2, prolong the working life of piston ring, thereby prolong the working life of machine.
3, since the raising of piston ring packing performance can reduce compression ring road number, can improve Explosive Motor Behavior comprehensively, reduce fuel consume, improve power performance, reduce frictional loss, improve mechanical efficiency, reduce the internal combustion engine noise.
The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 6 is the sectional view of tablet when being used for preventing simultaneously opening and preventing that back clearance from leaking of the present utility model.
Fig. 7,8,9 is the mounting type of tablet of the present utility model.
As shown in Figure 1, 2, the utility model is made of the pot type piston ring, in gap-clearance of piston rings place 2 tablet 1 is installed.When being used to prevent that opening from leaking, tablet 1 is installed on the pressurized end face 3 of gap-clearance of piston rings place 2, promptly at A, B two ends pressurized end face 3 places of gap-clearance of piston rings place 2 tablet is installed, and makes gap-clearance of piston rings form flexibility and takes mouth.When the piston ring pressurized, tablet can fit tightly end face automatically and play seal action, and the lubricant oil in the piston ring groove can play the effect that helps the tablet sealing, thereby prevents that opening from leaking, and the installation of tablet should guarantee that piston ring freely stretches.
Shown in Fig. 3,4, when being used to prevent that back clearance from leaking, tablet 1 is installed on the inner headed face 4 of gap-clearance of piston rings place 2.Under the back pressure effect, tablet plays the effect of sealing back clearance.
Shown in Fig. 5,6, when being used for preventing simultaneously that opening leakage and back clearance from leaking, tablet 1 adopts the right angle tablet 1 of one, is installed on the pressurized end face 3 and inner headed face 4 of gap-clearance of piston rings place 2.Tablet can be a kind of elastic spring etc.
Shown in Fig. 7,8,9, for preventing the tablet slippage, tablet of the present utility model can adopt tablet one end to be connected with gap-clearance of piston rings one end face with the contact structures of end face, and its connecting means can be adopted welding, riveted joint, embedding, form such as bonding.
