Latest Patents

One of Hartley's latest patents is an "Apparatus and method for pressure relief in an exhaust brake." This invention features a body with a passageway for exhaust gases, where a valve member can move between an open and closed position. In the open position, exhaust gases can flow freely, while in the closed position, the valve member blocks the passageway. The valve member includes an aperture that allows a limited flow of exhaust gases when open. An actuator mechanism is coupled to the valve member to facilitate its movement. Additionally, a closure member is positioned adjacent to the aperture, which can either permit or inhibit the flow of exhaust gases. The relief actuator mechanism ensures that the closure member maintains its position when exhaust gases are below a predetermined pressure.
