摘要： A servovalve has a sleeve (104) having both a first metering aperture (122-1) and a second metering aperture (122-2) in fluid communication with a single port cavity (114-1) defined by the servovalve. A spool (106) oriented within the sleeve has a first land (130-1) and a second land (130-2) and defines a channel ( 132-1) oriented between the first land and the second land. When the spool orients in a null position within the sleeve, the first land overlaps the first metering aperture and the second land overlaps the second metering aperture. As a low viscosity fluid within the servovalve assembly leaks across the first land and enters the channel, the overlap of the first and second lands with the first and second metering apertures minimizes flow of the fluid from the channel into the port cavity associated with the metering apertures. The configuration of the sleeve assembly, therefore, maintains a relatively large pressure gain within the servovalve assembly.

摘要： Oscillation and other disturbance damping is provided for a system having a load driven by an electric motor. Damping is achieved using feedback in an active mode, where power is supplied in a normal operation mode of the electromagnetic actuator. A gear train or other mechanical advantage device is connected between the electromagnetic actuator output and a load, to form an electromagnetic actuator. Feedback is provided by measured force or torque transmitted between the actuator and load mass. In active damping, a high pass filter is used to receive feedback signals and filter out low frequency feedback. The motor coils of the motor are shorted, such as by using a switch. The induced motor current acts to inhibit load oscillations. A number of resistors are in the short circuit to tailor the damping characteristics of the motor.

摘要： A direct drive servo-valve (10) wherein rotational motion of a drive motor rotor (28) is converted into linear motion of a spool valve (16). The drive motor (26) includes a shaft (50) which has affixed to the end thereof a ball (54) which engages the spool valve. The ball is affixed to the shaft by providing a bore (52) internally of the shaft which is disposed eccentrically to the longitudinal axis of the shaft. The ball has a portion thereof (64, 66) ground off so as to provide an integral protrusion (60) which is received within the bore in the end of the shaft. The ball is permanently affixed to the shaft by brazing the protrusion into the bore and a planar surface (62) which surrounds the base of the protrusion to the end of the shaft against which it mates.

摘要： A hydromechanical differentiating system (10) for actuator dynamic stiffness enhancement and dynamic load damping. A free floating spool valve (12) receives a pressure signal and moves in opposite directions away from a null position. When the valve moves in response to an increase in the pressure signal (p1), it compresses fluid in a chamber (30) connected at the opposite end of the cylinder in which the spool moves and simultaneously connects a source of fluid (22) under pressure to the chamber causing the valve to return to its null position. Conversely, if the pressure signal decreases, the spool valve allows the fluid in the chamber to expand moving the valve away from the chamber and simultanously connecting system return to the chamber to decrease the fluid pressure in the chamber and cause the valve to return to its null position.

摘要： A solenoid valve for use in controlling the flow of pneumatic fluid under pressure between a pair of flow ports defined by a housing. The flow of fluid is controlled by a spool disposed within a bore and is movable between first and second positions. When in one of said first and second positions, the spool blocks communication between the ports and when in the other of said positions it allows communication between the flow ports. The spool is reciprocated by a motor means which includes a core of magnetic material connected to the spool so that when the motor is energized, the spool is placed in one of its first and second positions and when the motor is de-energized, a spring moves the spool to the other of its positions.

摘要： A position sensing assembly (22) includes a bearing element (62) and a helically shaped rotational member (64) used to drive a portion of a sensor assembly (60), such as a Digital Rotary Magnetic Encoder. Interaction between the bearing element and a helically shaped rotational member minimizes the presence of backlash in the position sensing assembly. Accordingly, as an actuator assembly (20) drives both a control element, such as a flight control surface (24), and the position sensing assembly, the sensor assembly generates an output signal that accurately reflects the position of the control element.

摘要： A slot cover (36) actuation assembly controls access through a slot (26) on a projectile. The slot cover (36) actuation assembly includes a slot cover (36), a fastener (38) (e.g., a screw), and an actuator (40) (e.g., a squib device). The fastener (38) is arranged to position the slot cover (36) at an installation position on the projectile. The slot cover (36) covers the slot (26) on the projectile when the slot cover (36) resides at the installation position. The actuator (40) is arranged to release the slot cover (36) from the installation position on the projectile. The slot cover (36) uncovers the slot (26) on the projectile when the actuator (40) releases the slot cover (36) from the installation position on the projectile, thus allowing a control surface member (34) (e.g., a fin) to deploy.

摘要： A fin control assembly includes a housing, an arm configured to couple to a fin and to steer the fin relative to the housing, and a locking member disposed within the housing. The locking member is configured to (i) lock the arm in a substantially fixed state to inhibit movement of the arm relative to the housing when the locking member is in an engaged position, and (ii) unlock the arm from the substantially fixed state to allow the arm to steer the fin relative to the housing when the locking member moves from the engaged position to a disengaged position. The locking member has a cylindrical body portion and a cylindrical end portion, which is eccentric with the cylindrical body portion, to enable the locking member to lock the arm in the substantially fixed state while the arm holds the fin in a neutral location.

摘要： A pneumatic collet assembly (20) has a housing (40), a piston (42), a collet (44), and ball bearings (48) . The piston (42) is disposed within the housing (40). A bore (92) within the piston (42) receives the collet (44). The collet (44) has a base (116) and fingers (120). The fingers (120) of the collet (44) define a center channel or bore (126) configured to receive a torsion bar (30). The central channel (126) extends along a longitudinal axis (38). The ball bearings (48) are disposed between the piston (42) and the fingers (120) of the collet (44). The piston (42) is configured to move between a first position along the longitudinal axis (38) and a second position along the longitudinal axis (38) in response to pressure changes within the housing (40). The piston (42) increases force against the ball bearings (48) to urge the fingers (120) of the collet (44) against the torsion bar (30) to clamp the torsion bar (30) .
