Description

ABSTRACT:
A connecting rod assembly has universal joints at the ends of a connecting rod of tubular construction, the universal joints being lubricated by grease contained in the tubular rod and retained in the universal joints by flexible boots disposed about the exterior of the universal joints, the tubular rod containing a pair of pistons between which fluid from exterior of the universal joints can enter the tubular rod and equalize the pressure in the universal joints with the external fluid pressure.
The connecting rod assembly is installed between the rotor of an in-hole fluid motor of the progressive cavity type and the drive shaft of a bearing assembly for a motor driven drill.
