Title: Rufus L. Hawk: Innovator in Pump Technology and Engine Control
Introduction
Rufus L. Hawk is a notable inventor based in Xenia, OH (US), recognized for his contributions to pump technology and engine control systems. With a total of 2 patents, Hawk has made significant advancements in the field of mechanical engineering.
Latest Patents
Hawk's latest patents include a diaphragm pump and an idle speed control device for internal combustion engines. The diaphragm pump features a diaphragm mounted in a housing that defines both a pump chamber and a gear chamber. A cam follower is reciprocably mounted in the gear chamber and secured to the diaphragm. The rotary cam-gear, which is rotatably mounted in the gear chamber, has an annular cam face that engages the cam follower to reciprocate the diaphragm when driven by an electric motor through a single-stage reduction gear set. Additionally, a compression spring located in the pump chamber expands the pump chamber and maintains the cam follower's engagement with the cam face.
The idle speed control device is designed to be compact and utilizes a miniature DC motor connected by a speed-reducing gear train to drive a threaded shaft. This mechanism adjusts the position of a throttle stop for an engine throttle valve lever, thereby controlling the engine's idle speed. The throttle stop is initially moved by the throttle lever to close a normally open switch within the device, enabling motor operation only during idle. The threaded shaft disengages from the gear train when the throttle stop reaches a maximum throttle valve opening position, while the motor continues to run and re-engages when the motor reverses.
