Patent ID: 7828017

Claim:
A valve tester system comprising: a support; an articulated extension assembly having a mounting portion and an interface portion, the mounting portion being coupled to the support, the mounting and interface portions of the extension assembly being movable toward and away from each other, the extension assembly having at least two elongated extension links connecting the mounting and interface portions, each of the at least two elongated extension links having a longitudinal axis and opposite longitudinal ends, each extension link being pivotally coupled to another one of the extension links towards one of the longitudinal ends of the link, the at least two extension links including an inboard link and at least a second link, the inboard link being located toward the mounting portion of the extension assembly, the inboard link being pivotally coupled to the second link, the pivotal coupling of the links permitting pivoting about a vertical axis; an articulated arm assembly having a first elongated arm and a second elongated arm, the second elongated arm being pivotally coupled to the first elongated arm at a pivot point, the pivot point permitting pivoting about a horizontal axis, the first elongated arm being coupled to the interface portion of the extension assembly, the first elongated arm being pivotable about a substantially vertical axis with respect to the interface portion of the extension assembly; and a valve tester assembly coupled to the second elongated arm of the articulated arm assembly, the valve tester assembly including a motor, a motor control, a rotating connection rotatable by the motor, the connection being configured to connect to a valve to move the valve between open and closed positions, the motor control effective for controlling the rotation of the motor and the valve, and wherein the extension links are each movable with respect to the support and the extension links move in a generally horizontal plane and pivoting relative to each other to move the valve tester assembly toward and away from the support.
