Patent ID: 7575029

Claim:
A tool assembly in combination with a hydraulic fluid system including a housing defining a threaded bore with a valve seat receiving an end surface of a tubular bleeder valve member threaded into said bore and with said bleeder valve member having a head portion and movable axially between a closed position and an open position relative to said seat in response to rotation of said bleeder valve member, said tool assembly comprising a tubular body supporting a rotatable annular tubular nut member having an opening slidably engaging said head portion of said bleeder valve member and effective to rotate said bleeder valve member between said closed position and said open position without axial movement of said nut member, a resilient sealing member between said nut member and said housing of fluid system, a tubular member extending axially within said tubular body and releasably connected and sealed to said head portion of said bleeder valve member, a latch mechanism operable to move said tubular member axially within said tubular body for connecting said tubular member to said bleeder valve member and to clamp said nut member to said housing of said fluid system with said sealing member forming a fluid-tight seal between said nut member and said housing of said fluid system, a passage extending through said tubular member to said bleeder valve member and adapted to be connected to an evacuating source, a vacuum tester and a pressurized fluid supply source, and said bleeder valve member being movable axially between said open position and said closed position in response to rotation of said nut member while said sealing member maintains said fluid-tight seal between said nut member and said housing of said fluid system.
