Latest Patents

One of his latest patents is for a rotary actuator, which presents an improved fluid supplying and exhausting arrangement for fluid-powered rotary motion actuating devices of the dual piston rack-and-pinion type. This invention features a first conduit arrangement that includes a central opening through an axial end wall of the actuator housing. A fluid transfer tube is fitted in this opening and extends axially through the adjacent piston into the intermediate fluid chamber between the two pistons. This design allows for effective delivery and exhausting of fluid from the intermediate chamber, with the adjacent piston being slidable on the transfer tube in sealing contact. Additionally, a second conduit arrangement includes another axial opening in the end wall into the adjacent outward chamber of the housing, along with another transfer tube that extends axially through one piston and opens at the opposite ends into the two outward fluid chambers of the device. This innovative fluid supply and exhausting system eliminates the need for internal porting and passageways in the annular walls of the housing, allowing for a more cost-effective and simpler fabrication process using standard materials.

Another significant patent by Killian is the apparatus for coupling a valve and rotary actuator. This invention provides a close positive coupling of an actuator to a ball valve through a bracket plate assembly that fixes the valve and actuator bodies together. The design ensures that reactive loads generated by valve actuation forces are applied to the valve body rather than the valve stem. This results in essentially only torsional actuation forces being applied to the valve stem, enhancing the overall efficiency and reliability of the system.
