Latest Patents
One of Ortlepp's latest patents is a hydraulic system designed for both open and closed-centered systems. This innovative hydraulic system includes a hydraulic pump, a reservoir, a hydraulic function such as a cylinder, and a power beyond valve. The system is engineered to control communication between the pump, the reservoir, and the cylinder effectively. The pump provides pressurized fluid based on the pressure in a load sensing port. To generate a pump controlling load sensing signal, a valve is proposed that can block or open communication between the feed line of the cylinder and the load sensing port of the pump. This valve operates based on control pressures acting on either side of a valve member, ensuring optimal performance.
Another significant patent by Ortlepp involves a control valve that features a valve housing with a valve bore. This valve includes a first valve member that controls fluid communication between a pump, a reservoir, and a hydraulic function. The first valve member is equipped with annular grooves that accommodate pressure-controlled seals. A second valve member, which is movable in the valve bore and connected to an actuator, works in conjunction with the first valve member to form a pre-control valve. This design allows for the effective management of pressurization of the seals, enhancing the overall efficiency of the hydraulic system.
