摘要： A two pole stationary coil rotary magnet motor (1) which provides for increased work and reduced rotary inertia. The motor consists of two main assemblies, a rotor assembly (2) contained within a rotor casing (3) and a stator and housing assembly (4) surrounding the rotor casing. One end of the casing is closed, whereas the other end is open to eliminate the need for a dynamic shaft seal. Fluid enters the casing at the open end (12) thereof to provide a lubricating fluid for the rotor bearings (7, 8) and a heat conductive path. The rotor casing isolates the critical movement of the rotor (6) from the contaminated atmosphere of the stator environment and allows replacement of the stator assembly (4) without disturbing the rotor assembly. A permanent magnet rotor (6) may be formed using one or more rare earth magnets (45) which may be suitably bonded to the rotor shaft. A protective cover (49) surrounds the rotor magnets to eliminate potential rotor magnet breakage contamination. The relationship between the rotor magnet angle and stator winding (40, 41) may be such as to produce a relatively large output work potential. Also, the lamination slot configuration and stator winding may be graded to optimize the torque versus rotation profile to more closely match the cosine function of various rotary to linear output gearing to provide a substantially constant force output.

摘要： A free piston engine pump converts combustion energy into hydraulic power in an efficient, controlled and relatively uncomplicated manner, for example, for vehicle propulsion, auxiliary system power, etc. The free piston engine pump is substantially naturally mass balanced having opposed engine pistons 5, driving respective in-line hydraulic pumps 3. An adjustable accumulator 49 with a deformable fluid-tight chamber 50 containing a compressible fluid stores and delivers energy for compression, and an arrangement of control valves 67-69 and check valves 62, 63, 65, 66 enables selective operation of the free piston engine pump in primary (high flow) and secondary (high pressure) modes. Plural free piston engine pumps la, 1b, may be interfaced for parallel operation sharing common elements 53', 64' and functions. Cycle rate, intermittent operation and start-up also may be controlled. Electronic monitoring and control 150 of one or more operational parameters of a free piston engine pump also are disclosed.

摘要： A 2-pole limited angle torque motor (1) including a rotor assembly (2) having one or more permanent magnets (5) which are magnetized in the diametrical direction and a stator assembly (3) having a pair of stator magentic pole blades (22, 23) surrounded by a high density layer wound stator coil (20), with stator pole flanges (28, 29) at opposite ends of the stator magnetic pole blades which create a cross flux through the stator and rotor assemblies that produces a limited angle turning torque in the motor. The permanent rotor magnets (5) along with stator magnetic poles (22) and magnetic housing (17) produce a magnetic reluctance torque that can be controlled to obtain a desired magnetic centering or de-centering spring rate for the rotor (2) at a particular torque or power level. A magnetically saturating flux path may also be made to occur in the motor at the end of the rotational design stroke of the motor to provide a magnetic stop for the rotor shaft (15).

摘要： A control actuation system (70) for an aircraft including an electro-mechanically controlled, hydraulically powered actuator (72) for driving a main control valve (26) of a dual hydraulic servo-actuator control system (10). The actuator includes a tandem piston (74) connected to the main control valve (26) which is controllably positioned by a staged valve (125) of relatively short stroke whereby a force motor (218) of minimum size and energy requirements may be used to directly drive the valve. The staged valve (125) includes a linearly movable valve plunger (184) for simultaneously controlling the differential application of fluid pressure from respective hydraulic system on opposed pressure surfaces (94, 96 and 98, 100) of respective piston sections (90, 92) to cause movement of the piston (74) in response to relatively short axial movement of the valve plunger as long as at least one hydraulic system remains operative. Also, the staged valve (125) includes a fault control valve sleeve (130) concentric with the valve plunger (184) which, upon shut-down or failure of both hydraulic systems, moves linearly to render the valve plunger inoperative and release fluid pressure from opposed, corresponding pressure surfaces (94, 96 and 98, 100) of the tandem piston to respective returns therefor through respective centering rate control orifices (118,120, 250, 252) in the fault control valve sleeve (130) as the piston in moved to a neutral position by a centering spring device (254) acting on the main control valve.

摘要： A two-pole limited angle torque motor (1) including a rotor assembly (2) having one or more permanent rotor magnets (5) and a stator assembly (6) including a stator coil (9) and a pair of circumferentially spaced stator pole structures (10, 11). Each pole structure (10, 11) includes a generally axially extending stator pole blade (14) about which the stator coil (9) circumferentially extends. A radially outwardly extending flange (15) is at one end of one of the stator pole structures (10) and at the opposite end of the other stator pole structure (11). The stator pole blades (14) have a greater radial thickness (20) adjacent the flanges thereof than at the opposite end of the blade to reduce the magnetic flux density of the stator pole structures in the region of the blades adjacent the flanges thereof. Also, the axial outer end faces (21) of the flanges (15) desirably protrude axially outwardly adjacent the radial inner ends thereof to make use of the fringing fields of the rotor magnet at the ends of the rotor assembly to increase the reluctance torque of the motor. At the ends of the stator assembly (9) opposite the stator pole flanges (15) on opposite sides of the rotor assembly (2) are additional stator pole pieces (24). The blades (14) of the stator pole structures (10, 11) terminate short of the other ends of the rotor magnet (5) to provide room for the additional stator pole pieces (24) at such other ends for a given rotor length whereby the motor has a substantially higher reluctance torque without significantly reducing the torque due to interaction of magnetic fields. Surrounding the stator assembly in an outer magnetic housing (16) comprising two semi-cylindrical parts (30, 31) with air gaps (17, 18) between opposite sides thereof, said housing parts being rotatable relative to each other to change the size of one gap relative to the other or otherwise machinable to change both gaps equally for adjusting the reluctance torque of the motor.
