ABSTRACT:
A test in place poppet valve and fitting assembly having a minimal air volume internal configuration is provided for attaching a portable hydraulic test system to a snubber internal hydraulic line. The valve fitting includes structure for connection to the test system. After the valve fitting has been attached to the poppet valve, but before the poppet valve has been opened, a passageway and the interior of the poppet valve are evacuated and filled with hydraulic fluid. A remotely actuated, spring biased probe extends from the fitting through the passageway to engage a poppet for selectively opening the poppet valve. When actuated to an open position, a prong on the probe is inserted into a cavity, and the poppet is supported on the probe. Using the poppet valve and valve fitting, the test system may be attached to a snubber internal hydraulic line 12 without introducing an appreciable amount of air.
