Abstract: A variable pitch propulsor system with a propeller pitchlock system which utilizes a follower style pitchlock ballscrew screw which tracks the actuator axial stroke. The pitchlock system transfers the propeller yoke loads, from the ballscrew ballnut to the pitchlock nut allowing the propeller to pitchlock; utilizes the same screw thread lead angle for normal ballscrew back driving operation as well as pitch locking capabilities; provides a single ballscrew which is capable of both being back driven by the ballnut and structurally adequate for reacting the blade loads resulting from any flight condition; and minimizes the requirement of additional rotation and torque transferring interfaces between the ballscrew and pitchlock nut.

A seal element is mounted behind the pressure head and is radially extendable to engage a pipe inner wall. The second module has a mandrel defining a pressure head which, in use, is exposed to the fluid pressure between the first and second modules. Two axially spaced seal elements are mounted on the mandrel behind the pressure head and are radially extendable to engage the pipe inner wall.

Abstract: A valve body has an elongated bore in communication with an inlet port and an outlet port. A valve element is movable within the bore between deactuated and actuated positions. A valve sensor generates a sensor signal indicative of an instantaneous parameter of the valve that changes between the deactuated and actuated positions. A logic unit receives the sensor signal and a pilot command signal that actuates the valve. A predetermined change in the pilot command signal causes the logic unit to determine a cycle parameter responsive to a time period between two predetermined events. At least the beginning or end of the time period corresponds to a predetermined value of the sensor signal. The individual determinations of the cycle parameter are accumulated to obtain an expected cycle parameter. The logic unit generates an indication signal when the cycle parameter exhibits a predetermined variance from the expected cycle parameter.
