Patent ID: 8235256

Claim:
A pumping system comprising: a source of fluid for selective pressurization; a hydraulic mechanism structurally configured to apply high pressure to said fluid, the hydraulic mechanism comprising a trigger pivotally mounted within a housing, the housing including valves mounted therein that control the movement of fluid and also including a manually operable actuator at a distal end of the housing allowing manual pressure release by one hand of a user while holding the housing in the same one hand, the manually operable actuator selectively releasing pressure on said fluid within a conduit by releasing at least a portion of said fluid out of the conduit and external to the fluid source; the conduit selectively carrying said fluid from said source when said fluid is pressurized, the conduit extending from a proximal end of the housing that is substantially opposite of the distal end of the housing; and a container of a viscous material connected by a connector means to said conduit to receive pressurized fluid from said conduit to selectively force said viscous material from said container, wherein said connector means rotates about said conduit to permit selective bleeding of air from said container, wherein said connector means includes a hollow housing for receiving an end of said conduit through an axial opening therein; a set screw threadedly engaged with the interior of said hollow housing and surrounding said end of said conduit; seal means surrounding said end of said conduit; and ferrule means surrounding said end of said conduit, said set screw adapted to force said ferrule means and said seal means into contact with the interior of said hollow housing to provide a seal around said conduit in said hollow housing, wherein the valves include first and second automatic pressure valves such that a pressure chamber for said liquid is formed between said first and second automatic pressure valves, the first automatic pressure valve operable to allow said fluid to leave said pressure chamber and flow to said container when said pressurized fluid exceeds a first predetermined pressure threshold magnitude, the second automatic pressure valve operable to return pressurized fluid to said source when said pressurized fluid exceeds a second predetermined pressure threshold magnitude, wherein said second predetermined threshold is greater than said first predetermined threshold.
