PURPOSE:To enable a smooth and highly efficient operation, by composing a conversion means for converting reciprocating motion of a piston into rotational motion of a crank shaft with three interlocking plates connected together in a specific positional relationship. CONSTITUTION:In the occasion that this mechanism is applied to an air compressor A driven by a motor, a piston E and a crank shaft 10 in an air compressing part are interlocked with each other through a piston operation mechanism B. This piston operation mechanism B has an interlocking plate 1 one end of which is pivotally fitted on the lower end of the piston E, an interlocking plate 3 whose intermediate part is pivotally fitted on the other end of the interlocking plate 1, and an interlocking plate 2 one end of which is pivotally fitted on the supporting shaft 8 of a supporting point and the other end of which is pivotally fitted on one end of the interlocking plate 3. The other end of the interlocking plate 3 is pivotally fitted on the rotary shaft 9 of a crank shaft 10. On the other hand, the supporting shaft 8 is pivotally fitted on the supporting shaft displacement mechanism G including a displacement plate 4 capable of being adjusted in its operation by a displacement screw 12, around a displacement shaft 11. |
