Title: The Innovative Contributions of Robert David Jacobson
Introduction
Robert David Jacobson is a notable inventor based in Saint Paul, MN (US). He holds a total of 3 patents that showcase his expertise in engineering and design. His work primarily focuses on hydraulic systems and valve mechanisms, contributing significantly to advancements in these fields.
Latest Patents
One of Jacobson's latest patents is the "Cross-over relief valve assembly for use in bi-directional circuit." This invention features a relief valve assembly designed for use with two conduits, one of which communicates high pressure. The assembly includes a housing that defines first and second ports, along with a poppet seat. A poppet member and the housing create a spring chamber, where a spring biases the poppet member toward the seat. The poppet member also defines a shuttle cavity and a shuttle passage that connects to the spring chamber, allowing for efficient pressure management.
Another significant patent is the "Push-pull coupling." This invention is designed for coupling a valve spool to a coaxial cable and includes a lost-motion connection. This connection allows for the disconnection of the coaxial cable from the valve spool in a first mode and a positive connection in a second mode. The transition between these modes is achieved by energizing an electromagnetic actuator, which locks the components together to transmit motion. This push-pull coupling is particularly useful in hydraulic machines, ensuring safety by preventing operation when a driver is not seated.
