The purpose of this utility model is achieved in that
A kind of zero leakage piston ring mechanism, this piston ring is the toroidal that opening is arranged, be contained in the annular groove of outside piston, the annular groove width of described outside piston is greater than the thickness of piston ring, piston ring and spring are housed in this annular groove, and this spring pressure suitably is pressed in the contact plane of piston ring on the supporting surface of piston ring groove and realizes radially gapless sealing.
Between described piston ring and spring pressure ring is housed, this pressure ring is the toroidal that opening is arranged, and the aperture position of its opening and piston ring staggers mutually.
The external diameter of described pressure ring is less than the external diameter of piston ring.
The external diameter of described pressure ring and thickness are identical with piston ring and become second piston ring, and the aperture position of this two piston ring staggers mutually.
Described spring is the butterfly spring, and it is lumpy toroidal, and an opening is arranged on its toroidal surface.
Groove top, bottom land and the piston only of described annular groove outside piston is linking body structure.
The internal diameter of thereon piston ring of the structure that one of the groove of described annular groove outside piston top, bottom land and piston only are fixed together for the split suit, the bottom land external diameter of the annular groove of this piston only and suit, pressure ring, spring is corresponding.
The described quantity that is contained in the piston ring in the same piston ring groove can be more than one, and the aperture position of each piston ring staggers mutually.
The utility model has following actively useful effect:
This product uses the piston ring that the supporting of butterfly spring is arranged, and piston ring is pressed on the piston ring groove supporting plane, constitutes radially gapless sealing.The utility model also adopts the technological scheme that the opening more than a piston ring and each piston ring staggers mutually is housed in a piston ring groove, thereby can realize radially zero leakage of gas.So just, realize the gas in the jar zero leakage from radially, axially having blocked the leakage way of gas in the jar.Thereby reach the reduction oil consumption, energy saving improves mechanical efficiency.After piston ring used a period of time to cause gap-clearance of piston rings to increase because of the external diameter wearing and tearing, this product still can compensate the function that the blocking-up gas in the jar leaks, and prolonged piston ring working life, reduced user cost.This product realizes easily that also exhaust emissions is up to standard, the favorable environment protection owing to have gas in the jar zero leakage function.
