CN2510636Y - Environmental-protection energy-saving piston ring - Google Patents

Abstract

The utility model discloses an environmental protection and energy saving piston gas ring. In the using process, the public piston ring end gap is increased because of the wear between the ring and a cylinder, which causes the disadvantages that the airtightness becomes worse, the compression ability deteriorates, and the dynamic sudden loss appears frequently. The gas ring which uses two complementary seal rings is designed according to the above disadvantages of increasing the energy consumption and polluting the engine oil and the environment. The gas ring has the advantages of environmental protection, energy saving and prolonging the service life, and can be widely used for the engine and the compressor.

Description

Feature of environmental protection energy-saving piston ring

The utility model relates to the piston ring compression ring, particularly provides the energy-saving piston that is beneficial to environmental protection seal ring.

Present existing piston ring compression ring exists because of wearing and tearing after-opening gap increases, and the seal variation occurs, produce that combustion gas seals in that crankcase pollutes that machine oil and compressibility become that ring, energy consumption increase, power character prominent lose and ring a series of shortcomings such as scrap in early days.

In order to address this problem, people adopt the piston ring of plated film alloy to wait the antiwear property that improves ring.But this method can not solve the shortcoming that causes effect same owing to the wearing and tearing of cylinder body.

The utility model aims to provide a kind of feature of environmental protection energy-saving piston ring, increases and environmental pollution because of the energy consumption that ring and cylinder body, the caused seal variation of tangent line wearing and tearing on ring limit cause with effective eliminating.Make and be able to tangible prolongation in working life of ring.

The utility model is in the annular groove that a slice piston ring packing compression ring will be installed, and adopts the piston ring compression ring with the complementary sealing of two bursts.

So just, sealed with another burst complementation the fluid of stream string in the opened gap that increases because of the back of wearing and tearing and cylinder body (A) and the formed space of piston (B).

Below in conjunction with accompanying drawing structure of the present utility model and working procedure are described in detail.

Accompanying drawing 1, structural drawing of the present utility model

The complementary seal ring E of complementary another burst of seal ring D of A cylinder body B piston C burst compression ring boss F compression ring location cotter way among the figure

Specific implementation of the present utility model is: adopt not point-blank the compression ring with the complementary sealing of two bursts of opened gap in the groove that a slice sealing piston ring compression ring is installed.Promptly on one side face that the complementary seal gas ring (C) of burst and another burst complementation seal gas ring (D) combine, it is identical with the complementary seal gas ring of another burst and can hold the boss (E) that contains the complementary seal gas ring opening of another burst to produce a thickness, can produce a piston ring location cotter way (F) at the following of boss (E).

Boss (E) on the complementary seal gas ring of burst (C) holds in the opening that is contained in the complementary seal gas ring of another burst (D) like this, mutually so, relative being positioned of opening of seal ring (C) and another seal ring (D), the opened gap of two bursts can not be created on the same straight line, the prominent generation of losing of power character when having prevented to be on the same straight line after increasing because of the opened gap of seal gas ring.Has the compression ring that opened gap can not be created in the complementary sealing of two bursts on the same straight line owing in the seal gas ring groove, having adopted simultaneously; the infringement fluid of feasible space stream string after the opened gap increase; airtight by another complementary sealing burst compression ring; good airtight performance and compression have been ensured; pollution and destruction have been prevented to crankcase machine oil; thereby help environmental protection and energy-saving and cost-reducing; obviously prolonged the working life of ring, significantly improved at maintenance and the comprehensive economy in energy-saving and cost-reducing and working life.It is a kind of outstanding feature of environmental protection energy-saving piston ring.

Claims (4)

1, feature of environmental protection energy-saving piston ring is characterized in that adopting the piston ring packing ring with the complementary sealing of two bursts in the annular groove that a slice packed-piston compression ring is installed.

2, feature of environmental protection energy-saving piston ring according to claim 1 is characterized in that the opened gap of the complementary seal gas ring of two bursts does not produce on same straight line.

3, according to claim 1,2 described feature of environmental protection energy-saving piston rings, it is characterized in that on the complementary seal ring (C) of two bursts and one side face of (D) combining, make that to have thickness and complementation to seal burst identical and can hold and contain the wherein boss of another burst opening (E).

4, feature of environmental protection energy-saving piston ring according to claim 3 is characterized in that having a piston ring to locate cotter way (F) in the below of boss (E).
