Abstract

A variable length connecting rod for an engine comprises a floating bush slidably mounted within a body of the connecting rod with chambers on opposing sides of the bush. Hydraulic fluid is transferred between the chambers via at least one channel to move the bush and shorten or lengthen the connecting rod. Embodiments of the connecting rod comprise a lever connected to a variable one way valve which controls the direction of flow of the hydraulic fluid between the chambers. Movement of the hydraulic fluid between the chambers is driven by pressure differentials resulting from the movement of the connecting rod.
