摘要： An actuator converts linear motion into rotational motion. The actuator includes a power piston having a longitudinal axis. The power piston is configured to move back and forth along the longitudinal axis. A slider bearing is disposed within a cross-bore opening in the power piston. The cross-bore opening has a slider bearing axis orthogonal to the longitudinal axis. The slider bearing is configured to move back and forth within the cross-bore opening. An output shaft has a central axis orthogonal to both the longitudinal and the slider bearing axes. The output shaft includes an eccentric shaft pin inserted through a slot in the power piston and disposed within a cavity of the slider bearing. The eccentric shaft pin is offset from the central axis of the output shaft. The reciprocating movement of the power piston causes the slider bearing to move back and forth rotating the output shaft.

摘要： A rotary actuator (100) is provided. The rotary actuator (100) includes a stator assembly (120) centered along a longitudinal axis of the rotary actuator. The rotary actuator also includes a rotor assembly (122) surrounding the stator assembly (120). The rotor assembly is rotatable about the longitudinal axis relative to the stator assembly. The rotary actuator also includes first and second bearing assemblies (142, 144) mounted at adjacent opposed axial ends of the stator assembly (120) and connected between the stator assembly (120) and rotor assembly (122) to allow for the rotation of the rotor assembly (122) about the longitudinal axis relative to the stator assembly. A hydraulic actuation arrangement is formed between the rotor assembly and the stator assembly. The hydraulic actuation arrangement includes at least one first pressure chamber (180) and at least one second pressure chamber (182). At least one of the at least one first pressure chamber (180) and the at least one second pressure chamber (182) has a variable volume.

摘要： A low energy stepper motor driven fuel metering valve (FMV) that eliminates the need for a position sensor is provided. The stepper motor rotates a cam that replaces the flapper valve used in conventional systems. The cam rotation increases the gap between the cam and nozzle on one side of the cam. The gap difference affects the pressures on the spool piston ends, which forces the piston in the direction that will return the cam-nozzle gap to a distance that results in a pressure balance to return. As a result, the relatively low energy stepper motor controls the relatively high energy hydromechanical system via the cam-nozzle-orifice system. The cam is precision machined and assures stroke/degree gain accuracy. The hydraulic system assures the piston tracks the cam essentially perfectly except for the effects of piston stiction forces.

摘要： A low energy stepper motor driven fuel metering valve (FMV) that eliminates the need for a position sensor is provided. The stepper motor rotates a cam that replaces the flapper valve used in conventional systems. The cam rotation increases the gap between the cam and nozzle on one side of the cam and decreases the gap between the cam and nozzle on the other side. The gap differences affect the pressures on the spool piston ends, which forces the piston in the direction that will re-equalize the cam-nozzle gaps. As a result, the relatively low energy stepper motor controls the relatively high energy hydromechanical system via the dual cam-nozzle-orifice system. The cam is precision machined and assures stroke/degree gain accuracy. The hydraulic system assures the piston tracks the cam essentially perfectly except for the effects of piston stiction forces.
