(54) Multi-layer coolant reservoir


(57) In various aspects of the invention a multi-layer pressurizable coolant reservoir includes an inner shell member shaped and configured to define at least one liquid storage chamber. An outer shell member is layered onto the inner shell member. The outer shell member is particularly adapted to provide structural stability and resist pressure deformation of the inner shell. The outer shell is isolated from the coolant by the inner layer. The material of the inner shell is selected for compatibility with the coolant.
