Abstract:
1. A system to charge an accumulator apparatus, comprising: a piston disposed within a housing to define a first chamber adjacent a first side of the piston and a second chamber adjacent a second side of the piston; a fill probe having a body and a passageway between a first end of the fill probe and a second end of the fill probe, the fill probe to be removably coupled to the piston to fluidly couple the passageway of the fill probe and the second chamber of the housing when the accumulator apparatus is in a charging condition; a valve fluidly coupled to the piston to enable fluid flow to the second chamber of the housing via the piston when the fill probe is coupled to the piston; and a safety collar removably coupled to a fluid port adjacent the first chamber, the safety collar having an aperture through which the fill probe extends when the safety collar is coupled to the fluid port.
