Abstract:
An apparatus including a stationary section having a first central fluid passage and operably connected to a drilling fluid inlet and a conduit, a rotating and reciprocating section having a second central fluid passage and operably connected to a tubular, wherein the rotating and reciprocating section reciprocates along a longitudinal axis and rotates in conjunction with the tubular and the conduit, and a third section having a third central fluid passage in fluid communication between the first and second central fluid passages, where the third section is operably disposed between the first and rotating and reciprocating sections to permit the rotating and reciprocating section to slide axially even during rotation and to permit only rotational motion at an end adjacent the stationary section.
