His work primarily focuses on enhancing the functionality and efficiency of hydraulic drive systems.

Latest Patents

Lacher's latest patents include a "Hydraulic Circuit for Travel Motor" and "Automated Shifting of Hydraulic Drive Systems." The hydraulic circuit patent discloses embodiments that include travel motor hydraulic circuits designed to control the provision of hydraulic fluid to a travel motor. This invention features a counterbalance valve that blocks hydraulic fluid flow in a neutral position, preventing unintended movement of power machines. Additionally, it incorporates an anti-cavitation valve that directs hydraulic fluid back to the travel motor to avoid cavitation.

The second patent, "Automated Shifting of Hydraulic Drive Systems," describes a drive system for propelling a power machine over a support surface. This system includes a hydraulic pressure source and a drive assembly with a hydraulic motor in fluid communication with the pressure source. The motor can switch between first and second displacement arrangements, controlled by a shift valve that receives pressurized fluid and provides a shift signal to the hydraulic motor. An electronic controller further enhances this system by controlling the displacement of the hydraulic motor based on load conditions.
