Abstract
A universal tail pipe connector includes a three-way valve disposed on a hollow, cylindrical housing having inlet and outlet ports in spaced registration along the longitudinal axis of the housing, each having an internal diameter at least as large as the largest outside diameter tail pipe to which connection is required, the connector further including an annular, inflatable seal of elastomeric material disposed in an annular collar portion of the housing adjacent the inlet port, the seal being responsive to positive pressure and vacuum pressure signals provided through the three-way valve from external sources of each in dependence on selectable operation by an operator, for retracting inside the annular collar in response to the vacuum pressure signals to permit unobstructed penetration of the tail pipe through the inlet port into the housing, and for inflating in response to the positive pressure signals to provide a surface seal along the contour of the outside diameter of the enclosed tail pipe.
