pushrod

1. (mechanical engineering) A rigid reciprocating rod that, by its movement, transmits force to actuate a mechanism.Examples: "The cam-within-a-cam concept has existed for decades, but perfecting it for production might just add another decade to the life of the pushrod engine."

2. (mechanical engineering) A rigid reciprocating rod that, by its movement, transmits force to actuate a mechanism.Examples: "An internal-gear hub with a hollow axle may be re-oiled by removing the pushrod or indicator spindle and squirting oil into the end of the axle."; "Push Rod (81.85 mm) for Axle Length 168 mm"

3. (mechanical engineering) A rigid reciprocating rod that, by its movement, transmits force to actuate a mechanism.Examples: "On 17 August 2005, a Saab 2000, at the ramp, with controls locked, was subjected to jet blast of around 126 kt (233 km/h) from a passing B747. This resulted in the bending of the left aileron control pushrod, causing it to fail at the time of takeoff. The crew had to make an emergency landing."
