Latest Patents
Walsh's latest patents include a pneumatic door operator featuring a pneumatic actuator and lock. This power door operator is designed for transit vehicles and utilizes a rodless pneumatic cylinder as the primary mover for opening and closing doors located in the sidewall of these vehicles. The door movement is characterized by a controlled, predetermined door edge force, achieved through the mechanical coupling of an external piston of the rodless cylinder and the vehicle doors via an endless toothed belt.
Additionally, the magnetic coupling between the internal and external pistons of the cylinder provides a controlled force with a maximum or breakaway value applied to the operated door. A novel reaction lock, which is operated by the admission of pressurized air to the cylinder, allows for latching or unlatching the operated door in its closed position, either prior to or subsequent to door closing or opening. Control of door motion at the ends of its travel is facilitated by a unique differential area internal piston within the pneumatic cylinder. The available internal piston force is modified for predetermined piston positions as it approaches either end of the cylinder through the use of a sliding rod contained by the pressure-sensitive internal position. This movement of the sliding rod adjusts the effective piston area, thereby modifying the available force to control door motion.
