Hydraulic Actuator Valve

(Hydraulic actuators) A Hydraulic cylinder (also called a linear hydraulic motor) is a mechanical actuator that is used to give a unidirectional force through a unidirectional stroke. It has many applications, notably in engineering vehicles.

A cylindrical mechanism in a brass instrument that, when depressed or turned, admits air into different sections of tubing and so extends the range of available notes

a structure in a hollow organ (like the heart) with a flap to insure one-way flow of fluid through it

A device for controlling the passage of fluid through a pipe or duct, esp. an automatic device allowing movement in one direction only

device in a brass wind instrument for varying the length of the air column to alter the pitch of a tone

control consisting of a mechanical device for controlling the flow of a fluid

A membranous fold in a hollow organ or tubular structure, such as a blood vessel or the digestive tract, that maintains the flow of the contents in one direction by closing in response to any pressure from reverse flow

Boeing 737-300 port main gear, from the front.

This is the very first 737-300, which Boeing bought back from US Air at the end of its economic life. Boeing used it to try different possible causes for the two, suspected, hard-over rudder disasters which caused two 737s to upset suddenly and fly more or less straight into the ground. They even tested the "fat guy hypotheses", which posited that an extra heavy passenger had deflected or broken the floor of the airplane and that had caused the rudder to be driven hard over without a control input. No reasonable conclusion was ever reached from testing, but some improvements in the two input/two hydraulic system actuator for the rudder were made, the valve and actuator being redesigned to reduce a possible failure mechanism, and there had not been a repeat. Thank goodness. 101-0160_IMG

Porsche 956/962 transmission, suspension, spacer, hydraulic clutch actuator, antiroll bar, shift linkage

Anti-roll bar on left, over transmission. Upper arm of anti-roll assembly rotates around its long axis, stiff one way, less stiff after rolling 90 degree. The engine is mostly out of sight to the right. Clutch is in the bell housing just next to the engine, with the hydraulic actuator bolted to the bell housing. The starter motor and solenoid are painted white (nice), low and on the right. That's the gear shift linkage going across from lower right to mid left. One modest Rose joint links the essentially straight tube that the gear shift connects to (right) to a slightly curved tube that extends to the left and drives the shift mechanism on the transmission. 6e9_DSC_0373
