Tobias Lippa

Title: Tobias Lippa and Hydraulic Pressure-Release Innovation.

Introduction

Tobias Lippa is an inventor associated with Schwandorf, Germany. His patent work addresses hydraulic pressure management in work machines, with a focus on safely reducing pressure in worktool lines before a tool is disconnected.

Latest Patents

Lippa is associated with 1 patent, titled “Automatic Pressure Release.” The invention describes a controller that performs a worktool disconnect routine in a hydraulic system. The system includes a spool valve, two worktool ports and lines, a high-pressure hydraulic-fluid source, and a lower-pressure tank line.

During the routine, the controller checks that the work machine’s power source is operating and instructs the high-pressure source to stop supplying flow to the spool valve. It then moves the spool valve through two positions: first connecting one worktool line to the low-pressure tank line to reduce its pressure, and then connecting the other line to the tank line to reduce its pressure. This sequence is designed to relieve pressure in both lines during tool disconnection.

Career Highlights

Lippa is associated with Caterpillar Work Tools B.V. and Caterpillar Inc. His patent reflects work on hydraulic controls for machinery and on procedures intended to manage pressure during worktool changes.

Collaborations

James Edward Humphrey and Sebastian Jacob are identified as Lippa’s coworkers. The available information does not specify their roles in the patent or the extent of their collaboration.

Conclusion

Tobias Lippa’s “Automatic Pressure Release” patent focuses on a controlled sequence for reducing hydraulic pressure in both worktool lines, supporting safer and more manageable tool disconnection.
