Pneumatic Rack and Pinion Actuators Emerson US

Rack and pinion actuators are mechanical devices used to automatically open and close valves or dampers, usually for industrial applications. “Rack and pinion” is a generic term for a pair of gears which convert linear motion into rotational motion. A linear gear bar called “the rack” engages teeth on a circular gear called "the pinion".

Recirculating-ball Steering How Car Steering Works

May 31, 2001 Recirculating-ball steering is used on many trucks and SUVs today. The linkage that turns the wheels is slightly different than on a rack-and-pinion system. The recirculating-ball steering gear contains a worm gear. You can image the gear in two parts. The first part is a block of metal with a threaded hole in it.

Rack and Pinion Steering an overview ScienceDirect Topics

Rack and pinion steering systems are not suitable for steering the wheels on rigid front axles, as the axles move in a longitudinal direction during wheel travel as a result of the sliding-block guide. The resulting undesirable relative movement between wheels and steering gear cause unintended steering movements. Therefore only steering gears with a rotational movement are used.

Ball Valve an overview ScienceDirect Topics

The ball valve is an inexpensive alternative to other valves. Ball valves use a metal ball with a hole bored through the center, sandwiched between two seats to control flow. Used in many hydrocarbon process applications, ball valves are capable of throttling gases and vapors and are especially useful for low-flow situations. These valves are quick opening and provide a very tight closure on
