A rack and pinion gear train actuator for a pintle valve. A motor shaft has a pinion gear that engages a large reduction gear having an integral hub gear. The hub gear is a planet gear for a ring gear segment that pivots on a shaft and includes a pinion gear segment that engages a linear rack. The rack is attached to a valve pintle shaft, causing the valve to be opened and closed in response to rotation of the motor shaft. The pintle shaft, return spring, rack, and gears are all assemblable by slip fit. The actuator has a high actuation force, a fast response time, and compact design by virtue of a rack and internal gearing. The stroke of the rack may be changed for use with pintle valves having differing strokes by varying the angle through which the motor operates.
An actuator for displacing a shaft, comprising:
A gear train for converting rotational motion of a first shaft into linear motion of a second shaft, comprising:
A pintle valve having a pintle shaft and having a gear transmission for actuating the pintle shaft to open and close the valve, comprising:
An internal combustion engine comprising an exhaust gas recirculation valve, wherein said valve is a pintle valve having a pintle shaft and a gear transmission actuator, and wherein said actuator includes
An actuator for displacing a shaft, comprising:
