摘要： The improved servovalve broadly (20) includes: a body (21) having an axis of elongation (y-y), a portion of the body defining a cylinder (43) having an axis (x-x) substantially perpendicular to the body axis; a valve member (44) movably mounted in the cylinder, and adapted to be moved off-null in either direction along the cylinder axis to selectively meter the flows of fluid between a plurality of ports defined between the spool and cylinder; a rotor (58) mounted on the body for rotation about the body axis; a motor (69) acting between the body and rotor, and selectively operable to cause the rotor to rotate in a desired angular direction relative to the body; and a quill-like transfer member (64) acting between the rotor and valve spool.

摘要： A servovalve comprising a motor, a motor bias mechanism, a first stage valve having a first position, a second stage valve movable with movement of the first valve, a reference member in fluid communication with the second valve, a transfer link acting between the first valve and the reference member, an eccentric drive acting between the motor and transfer link, wherein movement of the motor causes the transfer link to move the first valve, movement of the first valve causes the second valve member to move, movement of the second valve applies on the reference member a pressure differential from a load, the pressure differential on the reference member causes movement of the reference member, and movement of the reference member causes the transfer link to move the first valve back to the first position.

摘要： Provided is a servovalve system for regulating fluid flowing within a fluid circuit. The servovalve system comprises a housing, a spool slidably disposed within the housing, a stepper motor operatively connected to the spool, and a controller and a position sensor electronically connected to the stepper motor. The controller generates driver signals representative of a desired amount of stepper motor rotation in order to cause the stepper motor to effectuate spool motion relative to the housing. The position sensor senses an actual amount of stepper motor rotation and generates a quantity of position signals representative thereof. The controller determines a signal ratio of the quantity of the position signals to the quantity of the driver signals and generates a diagnostic signal when the signal ratio reaches a threshold value representative of a predetermined level of mechanical resistance of spool motion relative to the housing.

摘要： A direct-drive, backlash-free servovalve in which the tip of an electric motor continually engages opposite sides of a receiving groove in the valve spool. The tip has a trapezoidal cross-section and tapers downwardly toward its extreme end. Rotation of the tip causes a translation of the valve spool, and can only progress until a side of the tip jams against one of the groove's sidewalls.
