Patent ID: 7024918

Claim:
Apparatus for dynamically pressure testing an article comprising: a first cylinder containing a first fluid; a first piston in contact with the first fluid and movable within said first cylinder; a shaker table mounting said first cylinder and said first piston for vibrating the first cylinder and first piston and generating pressure pulses in said first fluid; a second fluid cylinder in communication with said first fluid, said second cylinder and a second piston movably carried by said second cylinder being mounted independently of said shaker table, said second piston in contact with the first fluid on one side thereof enabling the generated pressure pulses to vibrate said second piston; and a second fluid in said second cylinder in contact with said second piston on an opposite side thereof from said one side for receiving pressure pulses generated by the vibratory movement of said second piston and transmitting the second pressure pulses to an article undergoing dynamic pressure testing in contact with the second fluid.
