Patent

CA 2501230

A dispensing device and method, especially adapted for use in sealing high pressure fluid leaks, is disclosed. Such use requires high pressure dispensing of sealant. Such sealants are formed by an exothermic reaction of at least two liquid substances that generates high pressures within the dispensing device. Such pressures could potentially harm the feeding system of the device due to pressure backflow. This problem is solved by providing a check valve in the mixing and reaction chamber of the device to protect the feeding system. A static mixer is disposed within the chamber to enhance mixing and reaction of the substances.
