Abstract

The utility model provides a laminated opening piston ring, which is composed of a piston ring body and a piston ring laminated opening; the piston ring laminated opening is arranged on the opening portion of the piston ring. The utility model is characterized in that steps which are fitted each other and can be overlapped together are horizontally processed on both ends part of the opening portion of the piston ring, and the thickness that the steps of both ends part of the piston ring are overlapped together is equal to the thickness of the piston ring body. The laminated opening piston ring has the characteristics of reasonable design, simple structure, easy manufacturing, small size, and convenient installation and operation; the power of the engine can be increased, and the fuel can be saved, etc.

Description

Lap-ended piston ring
The utility model relates to a kind of engine fittings, specifically a kind of lap-ended piston ring that is installed on the engine piston.
Piston internal-combustion engine will be strengthened sealing between cylinder and the piston to improve the power and the working efficiency of internal-combustion engine by piston ring.The structure of prior art piston ring is one the metal ring of vertical openings to be arranged, in use existing deficiency is, when in piston ring embeds the piston ring groove of piston, packing in the cylinder sleeve, the vertical openings of piston ring will be closed, only allow to keep certain clearance, (purpose that keeps opened gap is to prevent to take place when new engine from working under overburdening the cylinder accident that expands,) thereby, just there is the low defective of tightness in the design of the piston ring of this kind structure itself, along with cylinder sleeve and piston ring continuous wearing and tearing in use, the diameter of cylinder sleeve will strengthen gradually, the horizontal breadth of piston ring will diminish gradually, and the defective that the tightness between cylinder sleeve and the piston ring is low will be more and more obvious, and consequent result is that the opening of piston ring is increasing, the power of motor reduces, and fuel consumption increases.The way that solves is that motor is carried out large repairs, more rering or cylinder sleeve
The purpose of this utility model provide a kind of tightness good, can make motor improve power, fuel saving, the lap-ended piston ring in prolonging overhaul cycle.
The purpose of this utility model realizes in the following manner, is processed into the overlapping step that can coincide mutually at the two end part of gap-clearance of piston rings place, and the thickness after two steps are overlapping equates with the vertical thickness of piston ring.Like this, when in piston ring embeds the piston ring groove of piston, packing in the cylinder sleeve, the overlapped closed complete ring that forms of the step at piston ring two ends, along with cylinder sleeve and piston ring continuous wearing and tearing in use, the diameter of cylinder sleeve strengthens gradually, when the horizontal breadth of piston ring diminished gradually, the overlapped step in piston ring two ends was keeping overlap condition always, and piston ring remains a complete seal ring.Therefore, the tightness between cylinder sleeve and the piston ring remains unchanged, and the power of motor will improve, the consumption of fuel will reduce, the overhaul life will prolong.
Accompanying drawing 1 is the structural representation of facing of lap-ended piston ring;
Accompanying drawing 2 is the plan structure schematic representation of lap-ended piston ring.
Explain below with reference to Figure of description lap-ended piston ring of the present utility model being done.
Lap-ended piston ring of the present utility model, its structure are by piston ring body 1 and the folded mouthful structure of piston ring Become, the folded mouth of piston ring is located at the opening part of piston ring body 1, and its structure is at piston ring body 1 opening The both ends level at place is processed with the step 2 that can mutually coincide and can overlap, piston ring body The vertical thickness that the step 2 at 1 both ends overlaps equates with the vertical thickness of piston ring body 1.
Embodiment:
Its processing and fabricating of lap-ended piston ring of the present utility model is very simple and convenient, and processing shown in the by specification accompanying drawing gets final product.Processing technology is identical with the processing technology of pot type piston ring.Use also identically with the use of pot type piston ring, different is when installing in cylinder sleeve in piston ring of the present utility model embeds the piston ring groove of piston, the cylinder sleeve of packing into after making the step at piston ring two end part overlapped.
Lap-ended piston ring of the present utility model is compared with existing technology, have reasonable in design, structure is simple Single, be easy to processing, volume little, easy to install, can make engine improve power, save combustion The characteristics such as material, thereby, have good value for applications.
Except the described technical characterictic of specification, be the known technology of those skilled in the art.

Claims (1)

1. lap-ended piston ring, comprise folded mouthful of piston ring body and piston ring, it is characterized in that the folded mouth of piston ring is located at the opening of piston ring body, its structure is that the two end part level at piston ring body opening is processed with the step that can coincide mutually and can overlap, and the vertical thickness that the step at piston ring body two end part overlaps equates with the vertical thickness of piston ring body.
