Latest Patents

Welchel holds a patent for a "Pressure and temperature compensating hydraulic valve." This invention is crucial for controlling the operation of hydraulic elevators. As the elevator cab approaches a floor level, it must decelerate properly to ensure a smooth stop. The compensating valve he developed is interposed in the hydraulic line, replacing the traditional deceleration valve. It adjusts the transition time based on the load, ensuring that even with heavy loads, the elevator operates smoothly and safely. The valve also incorporates bi-metallic thermally responsive discs that modify its operation based on the temperature of the hydraulic fluid, further enhancing its functionality.
