Abstract
The utility model discloses a novel piston device for on internal-combustion engine, the device is formed by piston (2) and piston ring (3) equipment of laying in cylinder (1). Because the two piston rings (3) are combined, and the opening is relatively staggered by 180 degrees and is arranged in the annular groove, the sealing performance of the engine cylinder is better, the waste of fuel is avoided, the power is increased, the service life can be prolonged by more than one time, and the engine cylinder has the advantages of simple structure, convenience in installation and use and the like.
Description
The utility model relates to the piston apparatus on a kind of internal-combustion engine, the motor car engine.
Used piston on present internal-combustion engine and the air compressor, 2-4 road piston ring often is housed above it, effect is the slit between packed-piston and the cylinder wall, the back generation is expanded stuck in cylinder and annular groove and certain clearance is reserved in piston ring upper shed place in case stop ring is heated, opening on the ring is to guarantee that elastic force makes it to be attached to tightly the necessary condition on the cylinder wall, opening on the existing piston ring is as leaky on the container, and the size of leak is the difference of leakage rate.Its shortcoming is owing to opening is arranged, the fuel that the waste of sealing difference is a large amount of, the power and the working life of having reduced internal-combustion engine on piston ring.
The purpose of this utility model is that a kind of good airproof performance will be provided, and the energy fuel saving increases power, prolongs the internal-combustion engine novel piston device in working life.
The purpose of this utility model is to realize like this, this device is assembled by the piston and the piston ring that are placed in the cylinder, have annular groove on the piston, during assembling two piston rings merging are contained in the annular groove, and the opening of piston ring staggers 180 ° relatively, the opening of a piston ring is blocked by another piston ring, and the opening of its piston ring is the overlap joint type structure.
The utility model is owing to adopt the two-piston cyclization and the annular groove of packing into, stagger relatively 180 ° structure of opening makes that the cylinder of internal-combustion engine sealability is better, avoided the waste of fuel, increased power, increase the service life and to reach more than one times, it also has advantages such as simple in structure, easy to install simultaneously.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
Fig. 1 is the piston apparatus sectional view.
Fig. 2 is the piston ring structure schematic representation.
Describe specific embodiment of the utility model in detail below in conjunction with accompanying drawing, this device is assembled by the piston 2 and the piston ring 3 that are placed in the cylinder 1, have annular groove on the piston 2, during assembling 3 merging of two piston rings are contained in the annular groove, and the opening of piston ring 3 staggers 180 ° relatively, the opening of a piston ring 3 is blocked by another piston ring 3, and the opening of piston ring is the overlap joint type structure as shown in Figure 2.This piston apparatus only need add twice piston ring 3(compression ring) just can satisfy seal request, for being had, it solves pump oil phenomenon effectively, the advantage that good knife-type oil stripping action and easy break-in are arranged, piston ring 3 can adopt twist type ring, in addition, because of internal-combustion engine, the air compressor specifications and models are various, can change the size of piston ring 3 and the section configuration and the quantity of ring according to different type of machines.
Claims (2)
1, a kind of novel piston device, this device is assembled by the piston (2) and the piston ring (3) that are placed in the cylinder (1), it is characterized in that: piston has annular groove on (2), during assembling two piston rings (3) is merged, the opening 180 ° of angles of staggering relatively are contained in an annular groove.
2, a kind of novel piston device according to claim 1, it is characterized in that: the opening of piston ring is the overlap joint type structure.
