The servovalve assembly, designed to load aircraft engine compressor inlet guide vanes, comprises a two stage electrohydraulic flow control valve. The first stage consists of a proportional torque motor. The torque motor comprises two permanent magnets, two independent coils, armature flexure sleeve assembly (AFSA), and a flat fluidic amplifier with a flowguide, fixed pressure jet and two receivers. The second stage consists of a pressure driven sliding spool in bushing. Mechanical feedback between stages is provided by linking the AFSA to the spool. An inlet filter provides contamination protection to the first stage. A dual channel LVDT position transducer is mounted within the piston assembly with the probe fastened to the output end, and the body locked to the body assembly. The body and piston assemblies comprise an unequal area piston in a machined body. The piston assembly runs through the body assembly bore closed at the output end by a gland and at the other end by the LVDT and threaded plug. Supply, return and overboard drain ports are located on body assembly opposite the piston end. Threaded mounting holes in bosses at the piston assembly end provide for mounting. Passages in the body assembly are provided for fluid flow and for routing wiring from the transducer and torque motor coils to the electrical connector.

Hydraulic Motor 液压马达维修手册 Hydraulic Motor 液压马达维修手册--CMM-27-50-06， CMM-27-50-08Description.This motor is constant displacement, bent-axis, piston type unit. The direction of rotation iscontrolled by fluid flow through the unit by reversing fluid flow, the direction of motorrotation can be reversed. The motor may be operated in either direction continuously,intermittently or stalled without damage at rated pressures and in a system incorporating proper overload pressure relief. Motor mounting position is unrestricted, except that the case drain line must be connected directly to the hydraulic reservoir in such a manner that the motor housing remains filled with hydraulic fluid. Internal motor parts depend on this fluid in the housing for lubrication.

The fuse can then be reset by either flowing fluid in the reverse direction or by lowering the differential pressure across the fuse assembly to 5 psid. (34.5 kPa). There is also a threshold feature built in that will not allow the fuse to close when the flow rate is less than .02 gpm (.08 lpm).The major control elements of the fuse assembly are the slide and the sleeve. These two components, along with the regulator spring, form the regulator. The metering slot, which allows fluid to flow into the piston cavity, is located in the sleeve and is also controlled by the movement of the slide.
