Test apparatus for hydraulic valve

摘要

This disclosure relates to apparatus for testing a hydraulic assembly. The assembly includes a member having an orifice formed through a wall thereof and a valve member spring urged toward one side of the wall so as to close the orifice. The apparatus includes an enclosure for the assembly and hydraulic pressure means for applying hydraulic pressure to the opposite side of the wall around the orifice. The pressure applying means includes means for gradually changing the hydraulic pressure and indicating the pressure at which the valve member moves to open the orifice. The apparatus further includes means for supporting the assembly on a link so as to simulate actual operating conditions.
