Appl. No.:

14/470770

Polaris Industries Inc. - Medina MN

International Classification:

F21V 8/00
B62J 6/00

Abstract:

An apparatus and method for assembling a display device to which is coupled a light guide that has smooth surfaces for light-transmission and at least one surface that is for light scattering and internal reflection. The method includes depositing a reflective coating on that surface, and installing the display device with coupled light guide in an interior of a meter housing or casing. A portion of the casing interior is filled with a component, such as epoxy, for sealing the case interior to protect the display device and light guide against water and dust penetration. All surfaces of the light guide are protected from direct contact with the epoxy. This approach greatly simplifies the assembly process and yields a robust display that also prevents light leakage from the light guide.

Abstract:

Disclosed is a pressure compensator for a housing compartment that includes a housing wall that has an opening between an interior zone that is inside of the compartment and an exterior zone that is outside of the compartment. The housing wall also includes an annulus that defines one portion of the opening. A seal engages the annulus and is seated in the opening to seal the opening, the seal including a flexible diaphragm having a normally closed slit therethrough. The seal is configured so that the diaphragm is normally compressed in a first direction that urges the slit closed when the seal is engaged with the annulus. The diaphragm is arranged so that a pressure difference between the interior zone and exterior zone urges the diaphragm to flex in a direction for opening a slit thus creates a pathway between the interior zone and the exterior zone, thereby reducing the pressure difference.
