Abstract
The utility model discloses a novel piston structure. An open slot of a step type jogged structure is arranged on a steam ring. The utility model is characterized in that an arc-shaped groove is arranged on an inner cycle corresponding to the open slot, a shim is arranged in the arc-shaped groove, one end of the shim is fixed on the steam ring, and a spring making the steam ring expanded is arranged between groove bottoms of piston ring grooves of the steam ring and a piston. The utility model has the advantage of good sealing performance. A piston ring is automatically compensated under the action of the spring after worn, service life is raised substantially, consumption of fuels is lowered, and pollution is reduced. The novel piston structure is suitable for an engine and an air compressor.
Description
The utility model relates to a kind of novel piston structure.
The piston of present motor is generally and installs the cast iron ring with opening slot in the piston ring groove of piston, because engine operation is vapour ring generation wearing and tearing after a period of time, the exhaust emission pollution air of discharging, also cause energy waste, therefore the life-span of vapour ring is an important topic of many scientific research departments and the research of man of engine shop, but mostly these departments are to study from vapour ring material mechanical property at present, and the raising in life-span is limited.
The purpose of this utility model is to overcome above-mentioned deficiency, and design a kind of by the vapour ring, the novel piston structure that Shim and spring are formed.Increased substantially the working life of vapour ring.Specific power is constant mutually with new engine in the wearing and tearing rear engine.
The utility model content: a kind of novel piston structure, the vapour ring is provided with the opening slot of step type embedded structure, it is characterized in that: corresponding to being provided with curve bath in the vapour ring opening slot place, Shim is loaded in the curve bath, one end of Shim is fixed on the vapour ring, is provided with the spring that makes vapour ring distending between the bottom land of vapour ring and piston ring groove.
The utlity model has following advantage:
1. owing between the piston ring groove bottom land of piston and vapour ring spring is housed, after the wearing and tearing of vapour ring, under the effect of spring, vapour ring distending compensates automatically, has improved the cylinder sealing, the stability of maintenance output power.
2. because piston ring can compensate automatically, and the opening slot place of vapour ring is made as the step type embedded structure, tightness is good, has saved the energy.Alleviated the pollution of tail gas to environment.
Description of drawings:
Fig. 1 is the utility model plan view (signal).
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is that the B of Fig. 1 is to view.
Further specify the utility model below in conjunction with drawings and Examples.
Please referring to Fig. 1, the utility model is made up of vapour ring 1, spring 2 and Shim 3.Vapour ring 1 is loaded in the piston groove of piston 7, the vapour ring is made as the step type embedded structure, the left side that is an end at gap-clearance of piston rings groove place cuts one, form terraced structure 5, the right of the other end at opening slot place cuts one, form terraced structure 4, inside and outside terraced structure is superimposed and form two openings 6, in vapour ring opening slot, Shim 3 is housed, Shim is hiding the opening on week in the vapour ring, one end of Shim is fixedlyed connected with the vapour ring, and the other end fixedly is not in free state, and the length of Shim should be slightly less than the length of the curve bath of vapour ring.Between the piston groove bottom land of vapour ring 1 and piston 7, spring 2 is housed, please referring to Fig. 2, Fig. 3; During work, it is reciprocating along cylinder body 8 that piston is carrying the vapour ring.After the wearing and tearing of vapour ring, rely on the spring handle vapour hoop that is contained between piston and the vapour ring to eject outward, make the cylinder work as usual of motor, increased substantially working life.
