A device for deployment and actuation of a control surface for a maneuverable object, including an actuation shaft arranged for rotation about a longitudinal axis of the device; an output gear arranged concentric with the actuation shaft and configured to unlock the control surface when rotated about the longitudinal axis; and a pin integral with, or attached to, the actuation shaft and protruding through an opening in the output gear, wherein the output gear is operable to rotate about the longitudinal axis independent of the actuation shaft when the pin is in a circumferentially extending portion of the opening, and the output gear and actuation shaft are operable to rotate together about the longitudinal axis when the pin is in a longitudinally extending portion of the opening.

Control surface deployment and actuation

An actuation mechanism used in, for example, a missile assembly is disclosed, as are methods of its use. The actuation mechanism is locked in a first orientation and is unlocked in a second orientation. Locking and unlocking of the actuation mechanism is achieved by way of a locking mechanism that responds to a certain stimulus. In some embodiments, the actuation mechanism is incorporated into a sub-assembly of a missile to assist in controlling the missile's flight.

Actuation mechanism and associated methods

A pressure-regulating valve particularly useful in a diesel internal combustion engine with a closed crankcase is provided. The valve includes a body coupled to a bonnet with an internal movable piston. The movable piston maintains a substantially constant pressure in the crankcase by adjusting a fluid flow in response to changes in pressure. The movable piston also includes an integral relief valve to prevent overpressure in the event of a crankcase pressure in excess of the designed limits of the pressure-regulating valve.
