摘要： A rotor for use in a rotary position sensor includes an opening designed to receive a shaft having a flat. The rotor has a wedge within the opening designed to engage the shaft firmly but minimize insertion forces. Several troughs running parallel to the shaft and adjacent to the wedge aid in retention by adding a controlled amount of resilience to the rotor. On a shaft receiving end of the rotor there is an additional taper to help with coaxial alignment of the rotor opening and the shaft. On the shaft exiting end there is a half-moon like configuration designed to provide a force opposing surface during shaft insertion while not adversely impacting either the full insertion of the shaft or potential drag between the rotor and the sensor housing. The rotor is designed to offer unique advantage in insertion force to install the rotor on the shaft, while retention force and potential drag against the position sensor housing are minimized.
摘要翻译： 用于旋转位置传感器的转子包括设计成容纳具有平坦的轴的开口。 转子在开口内具有楔形件，其被设计成牢固地接合轴，但最小化插入力。 通过向转子添加受控量的回弹力，平行于轴并且靠近楔子延伸的几个槽有助于保持。 在转子的轴接收端上有一个额外的锥形，以帮助转子开口和轴的同轴对准。 在轴离开端，存在半月形构造，其设计成在轴插入期间提供相对表面的力，而不会不利地影响轴的完全插入或转子和传感器壳体之间的潜在阻力。 转子被设计成在插入力方面提供独特的优点，以将转子安装在轴上，同时保持力和对位置传感器壳体的潜在阻力最小化。

摘要： A remote control lever module comprises an inner shaft coaxially located inside an outer shaft. The inner and outer shafts are rotatably mounted on a support and can rotate with respect to one another. A return mechanism is engageable with the inner and outer shafts enabling forward rotation of the inner shaft to cause forward rotation of the outer shaft. The return mechanism further enables extended forward rotation of the inner shaft with respect to the outer shaft, and urges backward rotation of the inner shaft to a rearmost position. The return mechanism limits backward rotation of the inner and outer shafts beyond a nonactuating position. A force spring urges the outer shaft to the nonactuating position. Sensors produce electrical signals proportional to the angular position of the inner and outer shafts. A friction pad can be disposed between the inner shaft and support to frictionally resist rotation of the inner shaft with respect to the support.

摘要： A speed control apparatus for an internal combustion engine including a poppet valve seat and a poppet valve pintle assembly disposed coaxially for variably regulating the flow of air into the engine across the valve seat. The pintle is axially positioned by a stepper motor actuator responsive to an engine speed sensor and electronic controller. The controller varies the axial position of the pintle in accordance with a programmed algorithm to provide any desired engine speed, and especially a fixed engine speed, under a range of engine loads. The invention eliminates the need for a governor, rotary mechanical throttle, and cable or mechanical linkages, and is especially useful for small engine applications such as in powering a portable electric generator, yard equipment, or outboard motor.

摘要： An improved planetary traction drive mechanism for use in actuating a throttle valve assembly is provided. An electric drive motor supports a cup-shaped member defining the outer ring of the mechanism. The drive shaft of the motor extends into the cup-shaped member to define a sun roller and forming an annular space between the sun roller and the outer ring. An output plate is rotatably supported on the drive shaft, and one or more deformable planetary friction rollers are disposed in radial compression between the outer ring and the sun roller are mounted on the plate. An output shaft extends from the plate and may or may not be coaxially aligned with the sun roller. The output shaft may be connected via a link to a lever arm on the throttle shaft of the throttle valve, which may be used on an internal combustion engine.

摘要： A remote control lever module comprising a shaft rotatably mounted on a support. A friction pad has a pair or surfaces each of which frictionally resists rotation of the shaft with respect to the support and permits relative rotation between the shafts and the support. A bearing assembly is loosely fit about the shaft to assure that the shaft may rotate in the support.

摘要： A rotary throttle valve having a first cylindrical bore for flow of air between an inlet and an outlet and a second cylindrical bore orthogonal to the first bore and being substantially the same diameter as the first bore. A flow modulator rotatably disposed in the second bore has first and second cylindrical portions disposed respectively on opposite sides of the first bore and separated by a central plate such that when the modulator is rotated to place the plate transverse to the first bore, the edges of the plate are fully engaged with the wall of the second bore and the valve is closed. As the modulator is rotated from the closed position to open the valve, the edges of the plate become progressively less engaged with the wall of the second bore, the edge of the open area following the juncture lines of the first and second bores.
