Patent number: 11119516Abstract: Solenoid-operated pressure-regulator modules, aircraft inflatable slide assemblies, and methods for assembling solenoid-operated pressure-regulator modules are described. The solenoid-operated pressure-regulator modules include a primary inflation valve, a secondary inflation valve, a secondary valve actuator, a solenoid, an inflatable slide, and a gas source. The solenoid-operated pressure-regulator modules are configured to selectively enable a fluid connection between a gas source and an inflatable slide to enable inflation of the inflatable slide. The primary inflation valve includes a main cavity, a command cavity, an inlet through which a gas enters the main cavity, an outlet, a poppet that controls a gas flow from the inlet to the outlet, and a valve divider separating the main cavity from the command cavity. The secondary inflation valve is fluidly coupled to the outlet of the primary inflation valve.Type: GrantFiled: February 5, 2020Date of Patent: September 14, 2021Assignee: GOODRICH COPRORATIONInventors: Badarinath Nagaraj, Poly Puthur John

Patent number: 11092252Abstract: A valve assembly is provided and includes a valve housing, an actuator housing coupled to the valve housing and configured when actuated to open a normally-closed valve element in the valve housing whereby pressurized fluid is permitted to flow through the valve housing and a solenoid valve. The solenoid valve includes an armature-valve element balanced to remain in a closed position and an electromagnet. The electromagnet generates magnetic flux that moves the armature-valve element into an open position such that at least a portion of the pressurized fluid flows into the actuator housing to actuate the actuator housing.Type: GrantFiled: February 25, 2020Date of Patent: August 17, 2021Assignee: GOODRICH CORPORATIONInventors: Poly Puthur John, Jeevanandham Masilamani
