Interesting. I've been a VW fanboy for a very long time, but never really understood how a G-Lader works. Now, I wonder if this process can be reversed as an engine? Inject fuel and ignite it, I wonder if it works like a rotary engine?
1. This is a rotary air compressor, not an oscillating one. The scroll rotates continuously, it doesn't reciprocate 2. It is not a water pump, this is the system used in some old superchargers and is nowadays used in the best chillers and air conditioners 3. It is not inferior - scroll compressors are the most efficient of all compressors and they also have the highest tolerance to ingesting dirt and other nasty stuff - in fact these things can even suck up liquid refregerant without blowing up.
Its a Pretty cool concept VW invented but the main problem is that it tends to eat itself due to to the vibration caused by the snail looking 'turbines', which is also the reason they have stopped using this concept
@XELA2T Yes, they can compress the same mass of air with the same pressure ratio with less input energy. According to Wikipedia: "The efficiency of scroll compressors is slightly higher than that of a typical reciprocating compressor when the compressor is designed to operate near one selected rating point. However, the efficiency of a scroll compressor that does not have a discharge valve begins to decrease as compared to the reciprocating compressor at higher pressure ratio operation."
@XELA2T Sorry, I don't know what they sound like and I can only assume that their maximum compression ratio per stage is lower than that of a piston compressor. Regarding a fan, if you mean an axial compressor like the one on gas turbine engines, it's difficult to say since axial fan compressors are dynamic displacement compressors and thus the pressure ratio depends on the speed at which the fan is driven.
@LMF5000 Screw Types... I know they do it in a continuous manner. Tho that is achieved coz before the first "parcel" of air is fully delivered to the outlet, the next one opens up, so theres an overlap of this bursts. In effect, they result in a continuous flow.
@LMF5000 Hmm I think the effect is the same but its not Reciprocating... Theres a tiny window where the Scroll itself blocks the outlet and at that point the outflow pauses, So it might not be a Reciprocating design but its output is similarly in bursts or puffs. Tho I could be wrong.
@pimpb0tt I'm not sure... Reciprocating normally means going back and forth in a straight line (like the pistons in a normal engine). This orbits - a lot like the rotor in a Wankel engine minus the rotation about its axis. Would you classify that as reciprocating? Or as curvilinear motion?
@Detoyato You have a point. Though, to my knowledge, every kind* of positive-displacement compressor gives an output in bursts. You'd need a centrifugal compressor or an axial fan to give a constant output, but both are dynamic displacement not positive displacement. *I'm not sure if screw-type gives it in bursts.
@LMF5000 False, it's not a rotating compressor : the internal spiral oscillate on a excentric .Rotate a spiral is impossible...I think you confure with a palette compressor: this is rotative! For the history, the G compressor was invent by a french enginer in 1905, but was at this times, technicaly impossible to built
redundant. the water pump in my elgin 3.6 hp outboard runs on the same oscillating principles and doesn't contain silly, inferior, springy looking things.
This is amazing!

probably would work untill everything gets warm, starts expanding and then starts selfdestructing ike the normal G-Lader does normally :P

So good Animation.Wat is it?
@LMF5000
Actually, it is reciprocating. The scroll is not turning at all, its basically wiggling in place around a defined small orbit.

cool
Zekerzzzzzz hahahaha !! Lol :P
beste combo ooit zou dat zijn!

Que pasa si se rompió la parte inicial del espiral que está fija

thanks for this
gaaf he!! ;) Volkswagen gave shizzle! lol
by that logic a rotary is reciprocating too
omg i freacin pulled a teeth out of my mouth
vr6 met g lader:D
thats the shizznit:P
I think by 0:26 I got sleepy.

echt lijp hoe zo'n ding werkt he
Aridas

hahahahaha
