PATENTED 专利 The pneumatic actuator has a patented solution for the cam and the double adjustment stop bolts chamber. Such area is separated from the pistons chamber, and it is not subject to pressure containing, contrary to our competitors’ products. This solution reduces the eventual leaking points and it enables better performances and long-term reliability of our actuators. 气动执行机构拥有凸轮和双调整止动螺栓室的专利解决方案。与我们竞争对手的产品相反，该区域与活塞室分开，不受压力限制。这种解决方案减少了最终的泄漏点，使我们的执行机构具有更好的性能和长期可靠性。
