His work is characterized by innovative designs that enhance the efficiency and functionality of vacuum systems.
Latest Patents
Among his latest patents is the "Rolling diaphragm vacuum control with check valve." This invention is a vacuum controller designed to maintain a defined vacuum pressure to a remote location. It features a housing that defines a cavity, with means for connecting the cavity to the remote location, a high vacuum, and a control signal pressure. The design includes a cup-shaped plunger with an opening in its side wall, which is adapted to reciprocate within the cavity. A flexible diaphragm seals the interface between the housing and the plunger, functioning as a valving mechanism. When the plunger moves in one direction, the diaphragm closes off the opening in the side wall, and when it moves in the opposite direction, the opening is revealed. Additionally, a check valve is incorporated to prevent inversion of the diaphragms.
Another significant patent is the "Rolling diaphragm vacuum control." Similar to the previous invention, this vacuum controller is designed to maintain a defined vacuum pressure to a remote location. It also includes a housing that defines a cavity and means for connecting to the remote location, high vacuum, and control signal pressure. The cup-shaped plunger and flexible diaphragm work together to regulate the vacuum pressure effectively.
