ABSTRACT Camless internal combustion engines offer major improvements over traditional engines in terms of efficiency‚ maximum torque and power‚ pollutant emissions. Electromechanical valve actuators are very promising in this context‚ but still present significant control problems. Low valve seating velocity‚ small transition time for valve opening and closing‚ unavailability of position sensor are the main objectives to be considered in the design of the valve control system. Actuator physical

So for a beam to have a fixed connection to a column‚ along with clip angles‚ there may be a plate on the top and bottom flanges of the beam that gets welded to the column. With all that welding‚ the beam can no longer rotate. If a

Flanged couplings This is also a split-type coupling‚ but unlike the rigged coupling‚ the flanged coupling is split vertically. The two flanges are mounted on the shafts and then bolted together. The two halves can be bored to different diameters‚ or the flanged coupling can be purchased in a tapered bushing construction‚ allowing much more diversity. Rigid flanged couplings are available
