Latest Patents

Harry C. Evans holds a patent for a hydraulic door operator. This invention provides a simplified mechanism for two-speed operation and controls the release of a brake that normally holds the door against movement. The design includes a bypass valve between a fluid reservoir feeding the pump and the close control line running between the pump and the hydraulic motor. This allows for fluid flow to be directed from the close control line, enabling the door to close at a slower rate than it opens, all while utilizing a single-speed motor. A brake control valve is also incorporated to release the brake when the control lines are pressurized.
