Abstract:
A cooling system orifice adapter for coupling to an orifice and applying pressure from a source of pressurized gas, comprising:a hollow shaft having a distal end and a proximal end, and enlarged head portion at the shaft distal end, a threaded length along the shaft, and a central axial bore extending from the distal end to the proximal end, a universal fitting having a central axis, a distal end, and a proximal end, an exterior surface comprising a plurality of steps, said steps having substantially axially extending surfaces and substantially radially extending surfaces, said plurality of steps having outermost diameters which increase from the distal end to the proximal end of the universal fitting, at least one of said substantially axially extending surfaces being disposed from the outermost diameter at a negative angle relative to a line parallel to the axis, and an axial bore adapted to receive the hollow shaft, the threaded length along the shaft being at least partially accessible from the proximal end of the universal fitting, a plate having a bore extending therethrough adapted to receive the hollow shaft, a knob having a threaded internal bore adapted to receive at least a portion of the threaded length of the hollow shaft, the hollow shaft being disposed extending through the fitting axial bore and the plate bore, the enlarged head being disposed adjacent the distal end of the universal fitting and the plate being disposed adjacent the proximal end of the universal fitting, the threaded length of the shaft being received within the knob such that rotation of the knob causes the enlarged head and the plate to exert an axial compression force on the universal fitting between the plate and the enlarged head portion to force the exterior surface of the universal fitting outward to couple the adapter to said orifice, and a pressure adapter for coupling the shaft to a source of pressurized gas, the pressure adapter being adapted to sealingly engage the proximal end of the hollow shaft, the pressure adapter further including a pressure passage adapted to be in communication with the central axial bore of the hollow shaft such that pressurized gas may be applied from the source of pressurized gas through the pressure passage and the central axial bore.
