Coolant filler neck assembly for pressurized cooling systems
The patent US12000323B2 describes a coolant filler neck assembly designed for use in pressurized cooling systems. The assembly features a cylinder housing that defines a non-pressurized coolant overflow reservoir. Key components include an upper cap member that houses an overflow inlet port and a filler pipe, both of which facilitate fluid communication with the pressurized cooling system. The assembly incorporates two fluid overflow tube members: the first directs overflow liquid coolant into the non-pressurized reservoir, while the second allows for the discharge of excess coolant to the ambient environment. The design also includes various seal members to ensure hermetic sealing at critical interfaces, enhancing the assembly's reliability and performance.
In addition to the primary features, the patent outlines multiple claims that detail the configuration of fluid conduits within the overflow reservoir. These conduits include pressurized and non-pressurized pathways that manage the flow of coolant effectively. The assembly is structured to ensure that overflow liquid coolant is efficiently directed from the pressurized system to the reservoir and subsequently to the environment, minimizing the risk of leaks and maintaining system integrity. The claims further specify the arrangement and communication between the conduits, emphasizing the assembly's comprehensive design aimed at optimizing coolant management in pressurized systems.
