Embodiment Construction

[0010] The detailed description of one or more embodiments of the disclosed apparatus and methods is presented herein by way of example and not limitation with reference to the accompanying drawings.

[0011] figure 1 A cooling system 1 according to an embodiment of the invention is shown. The cooling system 1 includes a coolant source 10 , a refrigeration unit 12 and a coolant second destination 14 . Examples of coolant source 10 include storage containers for storing fluid coolant such as freon or carbon dioxide. The fluid coolant is delivered to the refrigeration unit 12 and the coolant second destination 14 via pipes, tubes or lines. Examples of refrigeration unit 12 include a refrigerator having a heat exchanger, a compressor, and an expansion valve to cool food or other perishable materials stored therein, or a system for cooling mechanical or electronic components. In one embodiment, refrigeration unit 12 is part of an aircraft galley and is used to store food for pa...

Abstract

An overpressure relief valve assembly includes an outer housing having an inlet at a first end opening to an inlet cavity and an outlet at an opposite second end opening to an outlet cavity, and a valve located in the outer housing, the valve including a valve housing that is fixed with respect to the outer housing and an actuator movable within the valve housing to alternatingly cut off and allow communication between the inlet cavity and the outlet cavity.

Description

technical field [0001] Exemplary embodiments relate to the field of fluid transfer systems, and more particularly, to overpressure relief valves for preventing overpressure in lines of fluid transfer systems. Background technique [0002] Valves are used to open and close the flow of fluid in the lines of a liquid delivery system. In some systems, such as a coolant system configured to supply coolant to an aircraft galley, one valve may control the flow of fluid to a first destination and a second valve may control the flow of fluid along a pipe that bypasses the first destination. the flow of the road. In some systems, if all valves designed to provide fluid to a destination are closed or blocked, pressure buildup in the system can create problems such as leaks or pump turbulence. Contents of the invention [0003] An overpressure relief valve assembly is disclosed comprising: an outer housing having an inlet at a first end open toward an inlet cavity and an outlet at a...
