Abstract

See full text

A wear-preventive air-charger piston structure is provided. The piston rod has a top forming a piston top seat on which a piston ring is disposed. The piston ring is covered with a top cover that is combined with the piston top seat. The top cover is provided with an airtight plate mounted thereto to form a complete piston structure. A buffering element is arranged between the piston top seat and the piston ring. The buffering element has an outside diameter smaller than the piston ring, so that when the piston ring, which is driven by a crankshaft to do an up-and-down movement, is put in an inclined oscillating condition and at a high position of an oscillation side, the buffering element functions to absorb the stress acting on the piston ring at the high position of the oscillation side to effectively prevent detachment and breaking of the piston ring.
