Title: Innovations by Patrick J Cunningham
Introduction
Patrick J Cunningham is an accomplished inventor based in Redondo Beach, California. He has made significant contributions to the field of flow control technology, holding a total of 2 patents. His innovative designs focus on enhancing the efficiency and safety of fluid management systems.
Latest Patents
Cunningham's latest patents include a Leak Arresting Valve and a Mechanical Leak Arresting Valve. The Leak Arresting Valve features a unique design where a housing defines a flow chamber with an inlet and an outlet. Within this chamber, a poppet assembly consisting of an inner and outer poppet is employed. A first spring biases the outer poppet to seal the inlet below a predetermined fluid flow rate. When the flow rate exceeds this threshold, the fluid pressure compresses the spring, allowing fluid to flow into the chamber. The inner poppet, which is biased by a second spring, extends to seal the outlet when necessary, effectively arresting the flow in case of a leak.
The Mechanical Leak Arresting Valve operates similarly, limiting fluid flow to a range between a predetermined minimum and maximum flow rate. This valve employs a locking mechanism triggered by a pressure differential caused by a downstream leak, blocking fluid flow until the upstream fluid source is stopped. Once the pressure is reduced, the valve automatically resets without further manipulation.
