Title: Douglas M Gage: Innovator in Hydraulic Control Mechanisms
Introduction
Douglas M Gage is a notable inventor based in Dubuque, IA (US), recognized for his contributions to hydraulic control mechanisms. With a total of 11 patents to his name, Gage has made significant advancements in the field of hydraulic systems, particularly for work vehicles.
Latest Patents
One of Gage's latest inventions is a hydraulic control mechanism for a hydraulic actuator. This invention is designed for work vehicles equipped with work implements operated by hydraulic actuators. The mechanism utilizes a pilot control system that sends a pilot control signal to the end caps of a main hydraulic control valve. It features two pressure sensing valves that manage the flow of hydraulic fluid from both a fixed displacement pump and a variable displacement pump. The first pressure sensing valve directs fluid from the variable displacement pump to the hydraulic actuator, while the second decouples one of the end caps of the main hydraulic control valve from the pilot sensing line, effectively shifting the valve to neutral and blocking fluid flow from the fixed displacement pump.
Another significant patent is the automatic pressure relief system for a hydraulic motor. This system includes a check valve assembly with first and second check valves and an unseating spool positioned between a control valve and a rotary motor. The unseating spool is designed to maintain contact with the valve elements of the check valves, allowing for efficient hydraulic pressure management.
