Pneumatic actuator for moving objects using pressurized gas
The patent US12066039B2 describes a pneumatic actuator designed to impart velocity to a resting object through a unique arrangement of ram members. The actuator consists of a fixed member with a base plate, an inner cylinder, and an outer cylinder, all concentrically aligned. The ram features multiple elongated members that are telescopically arranged, with the innermost ram member positioned within the inner cylinder. When pressurized gas is introduced through an inlet hole in the base plate, it initially acts on the innermost ram member, allowing it to move independently and drive the object. The other ram members are configured to engage only after the innermost member has been displaced, ensuring a sequential movement that enhances the actuator's efficiency.
Additionally, the actuator includes features that prevent the outer ram members from exerting force on the innermost member in the opposite direction during operation. It may also incorporate a shock-absorbing system to regulate the speed of the outermost ram member, ensuring it does not exceed the speed of the next inner member. The design allows for interlocking engagement between ram members, which can be activated after a predefined movement distance. This interlocking mechanism, along with the ability to drive ram members while interlocked, provides a stepwise compensation system that adjusts based on the average gas pressure during operation. The overall system, which includes one or more actuators, a gas reservoir, and corresponding activation valves, is engineered to facilitate controlled and efficient movement of resting objects using pressurized gas.
