Abstract:

A mobile wireless communications device may include a housing having an opening therein and an inwardly extending housing ring adjacent the opening, and a switch carried by the housing and being aligned with the opening. The mobile wireless communications device may further include a backing member within the housing adjacent the opening, and an elastomeric switch membrane comprising a body covering the switch, and a flange coupled to the body and compressed between the backing member and the housing ring to define a seal therewith. The flange may include a flange base, and a pair of flange rings extending inwardly from the flange base and defining a valley therebetween aligned with the housing ring. In another embodiment, the flange may include a flange base and a first flange ring on a first surface thereof, and a pair of second flange rings on a second surface of the flange base and defining a valley therebetween aligned with the first flange ring.

Abstract:

An refrigerant accumulator () comprises a first chamber (), a second chamber (), a pre-evaporator line (), a post-evaporator-inlet line (), and a post-evaporator-outlet line (). The chambers () are in a pressure-isolated arrangement and a heat-transfer relationship. The pre-evaporator line () passes through and communicates with the first chamber (). In a steady state, the pressure of fluid in the first chamber () is greater than the pressure of fluid in the second chamber (), but their temperatures are the same, and the pressure of fluid within the first chamber is balanced with the pressure of fluid within the pre-evaporator line. In a starved or flooded state, temperature differentials between the chamber () and chamber (), and pressure imbalances between the chamber () and the pre-evaporator line (), adjust the charge of refrigerant fluid to return the system to a steady state.
