Telescopic connecting rod for a variable compression ratio engine

A telescopic control connecting rod for a variable compression ratio engine, comprising:

• a small end with a longitudinal axis, having, at one end, an eye configured to establish a pivot link with a return member of the engine and having, at the other end, piston;
• a big end serving as cylinder body in which the piston defines a first hydraulic chamber and a second hydraulic chamber, the respective filling and emptying of which modify length of the control connecting rod, and a third side chamber located between the first hydraulic chamber and the second hydraulic chamber;
• the big end further comprising two coaxial side bearings, with a transverse axis normal to the longitudinal axis, configured to establish a pivot link with a fixed part of the engine;
• and
• a lubrication circuit comprising at least a first duct provided in the big end, establishing fluidic communication between an inner space of each coaxial side bearing and the third side chamber, whatever the length of the control connecting rod, and comprising at least one second duct provided in the small end, in fluidic communication with the third side chamber and opening into the eye.
