Patent ID: 7987923

Claim:
A valve testing assembly comprising: an articulated arm assembly adapted for coupling to a mobile base; a valve testing assembly comprising a valve tester having a rotating assembly and a rotating shaft having a first end operationally couplable to the rotating assembly for rotating the rotating shaft, the valve testing assembly coupled to the arm assembly to pivot around a substantially horizontal axis such that the rotating assembly is positionable in a substantially horizontal orientation at a selectable position in a three dimensional space adjacent the mobile base, the rotating assembly including a torque adjustment mechanism effective for adjusting torque so that a valve to which the rotating assembly is coupled will not be damaged; the arm assembly including a first arm adapted for coupling to the mobile base; the arm assembly including a second arm pivotally coupled to the first arm portion; a first resilient biasing assembly coupled between the first arm and the second arm which resiliently biases the first and second arm relative to each other; and a second resilient biasing assembly coupled between the rotating assembly and the second arm which resiliently biases the rotating assembly relative to the second arm.
