Abstract

A fluid inversion liner apparatus controls fluid loss to permit lining of pipe in smaller spaces by requiring less fluid. The apparatus includes a housing, a liner feeding assembly, and a nozzle. A tubular flexible liner is insertable through the liner feeding assembly. The liner has a first end couplable to the nozzle forming a fluid seal at the nozzle. A fluid injection port is provided for introducing fluid such as air or water into the housing. The liner feeding assembly is adjustable for conforming to the liner as the liner passes through the liner feeding assembly. Thus, fluid introduced into the housing through the fluid injection port is prevented from passing out of the housing through the liner feeding assembly. As a result, fluid pressure between the interior of the housing and the liner draws the liner through the liner feeding assembly and out of the nozzle.
