CN201096029Y - Superposed closed type piston ring - Google Patents

Abstract

The utility model discloses a superposition closed type piston ring arranged on an engine piston gas feeding ring groove. The piston ring is mainly composed of an upper ring (1) and a lower ring (2). An interface between the upper and the lower rings is a smooth plane. During the assembly process of an engine, after being staggered for 180 DEG, an upper ring opening (3) and a lower ring opening (4) of the superposition closed type piston ring are arranged in a piston ring groove, and then a special installation tool of the piston ring is used for installing a piston with the piston ring in a cylinder sleeve to realize the gas sealing function. By using the piston ring, not only are fuel consumption and oil consumption efficiently reduced, but also are the dynamic performance and the reliability, etc. of the engine enhanced. If the technology is popularized and applied to a vehicle engine, the performance of the engine can be enhanced in the aspect of performance index, economy and reliability, etc., and favorable social and economic benefits can be obtained.

Description

The stack sealed piston ring

Technical field

The utility model belongs to the component that are used to improve aspect performances such as engine power performance, reliability, Economy.

Background technique

Piston ring-cylinder liner is one of topmost friction pair in the motor.The fundamental function of piston ring has determined its structure that opening must be arranged, the existence of opened gap, help the installation and removal of piston ring in the final assembly process on the one hand, guaranteed that on the other hand piston ring itself has certain elastic force, make piston ring in engine operation process, can be close to cylinder-barrel surface, cause the fuel oil consumption to increase in the crankcase thereby effectively stop a large amount of combustion gas to be scurried into, stop a large amount of machine oil to scurry into cylinder from the gap between cylinder and the piston simultaneously and cause engine oil consumption to increase from the gap between cylinder and the piston.Therefore, piston ring is one of very important component in the motor.But the existence of opened gap also has its deficiency, and promptly under the condition of high combustion chamber pressures combustion gas, a part of combustion gas meeting is scurried in the crankcase by piston ring gap, and a part of machine oil also can be scurried in the cylinder by opened gap simultaneously.At above actual conditions,, developed novel stacked sealed piston ring for effectively solving the existing deficiency of opening piston ring itself.

Summary of the invention

The purpose of this utility model is a kind of stack sealed piston ring of exploitation, it is characterized in that: in the motor assembly process, with the stack sealed piston ring go up ring (1) and down (2) two on ring encircle openings and interlace after 180 °, burnishing surface is close together is installed in the piston ring groove, to have in the installing piston into cylinder cover of this piston ring with the piston ring special tool at last, realize the envelope airway dysfunction.

The beneficial effects of the utility model are that novel piston ring is adapted at installing and using on the various vehicular engines, its application can improve engine performance, prolong cylinder sleeve and piston life, power character, reliability and the Economy of improving motor had very big potentiality, and its predominant use is: (1) effectively reduces the fuel oil consumption; (2) effectively reduce engine oil consumption, prolong the life time of machine oil; (3) improve engine power performance; (4) functional reliability of raising motor.

Embodiment

The utility model provides a kind of stack sealed piston ring.In stack sealed piston ring schematic representation shown in Figure 4, the smooth flat that will go up ring (1) and following ring (2) fits tightly, utilize the piston ring setting tool to be installed in the piston ring groove, utilize the piston ring special installation tool will be equipped with two then and be superimposed and the interlace piston of 180 ° of piston rings of opening is encased in the cylinder sleeve of engine, thereby realize seal action combustion gas.

Claims (3)

1, a kind of stack sealed piston ring that is installed in compression on the engine piston is characterized in that: comprise that is gone up ring (1) and one ring (2) down, last ring and encircle the edge down and encircle an opening (3) and (4) are circumferentially respectively arranged.

2, according to the described stack sealed piston ring of claim 1, it is characterized in that: two superimposed surface of contact of ring are smooth flat, guarantee that upper and lower two loop contacts faces have degree of applying preferably.

3, according to the described stack sealed piston ring of claim 2, it is characterized in that: upper and lower two rings are when assembling, and its opening will interlace 180 °.
