ABSTRACT:
A fluid controlled counterbalance and power-assist system for use in a diagnostic x-ray imaging system includes a first member and a second member movably mounted to said first member. A slave actuator including a reciprocal piston is selectively coupled between the first and second members. Fluid coupling ports are located on each end of the cylinder for coupling working fluid to either side of the piston. First and second master actuators each including a cylinder are located remote from the imaging system. Each master actuator has fluid coupling ports selectively located on each end of its cylinder for coupling working fluid to one side of the cylinder and control fluid to the other side. Working fluid connection lines connect one end of the slave actuator to one end of the first master actuator and connect the opposite end of the slave actuator to the second master actuator for providing working fluid flow between said actuators. The coupling port on the opposite side of the first and second master actuators are individually connected to a source of fluid pressure. A control means comprising a handle operatively connected to a power assist actuator produces first and second pressure signals proportional to force exerted on said handle. First and second pressure regulator means are adapted to respectively receive the first and second pressure signals from the control means thereby controlling the pressure to the master actuators as a function of the force exerted on said control means handle. The first and second pressure regulator means are additional adapted to receive a first and second pressure feedback signal from said working fluid lines.
