Title: The Innovative Contributions of David L Anderson
Introduction
David L Anderson is a notable inventor based in Muskegon, MI (US), recognized for his significant contributions to the field of engineering. With a total of nine patents to his name, Anderson has made a lasting impact through his innovative designs and solutions.
Latest Patents
One of Anderson's latest inventions is a solenoid valve, which is a normally closed, three-way valve. This valve comprises a housing that includes a supply passage, a control passage, and an exhaust passage. The valve assembly is designed to control communication between these passages. It features a valve in the supply passage that opens and closes communication between the supply and control passages. Additionally, there is a second valve in the exhaust passage that manages communication between the control and exhaust passages. The supply passage valve is typically held closed by the pressure of hydraulic fluid in the supply passage. When activated, a solenoid moves the exhaust passage valve to a closed position. A pintle situated between the two valves shifts in one direction when the exhaust passage valve closes, allowing the supply passage valve to open against the hydraulic pressure. Conversely, when the solenoid is deactivated, the pintle shifts in the opposite direction, moving the exhaust passage valve to its open position. A spring in the supply passage assists the fluid pressure in closing the supply passage valve, ensuring it remains closed solely due to the hydraulic pressure.
