BTW, Chet,

The sock-type actuator doesn't have any force advantage over a diaphram type. The advantage is its essentially unlimited length of stroke.

Unlike a diaphram type, the throw of which usually cannot be more than an inch or so in practical versions, you could make a sock-type actuator with a two or three foot stroke just as easily as one with a

That can help your avoiding cludging up stroke-amplifying (and force dividing) bell-cranks and other such devices to get the stroke of the cylinder to match the throw of your throttle linkage.

Thank you for the additional info! It's appreciated!

Would you mind if I posted your info on another website,

Needless to say, you'll get full credit for the design and info... (Think you'd want to modify your original drawing to show the reversed rod and vacuum input? If not, I'll post it as it is with the suggested changes.)

I emailed you a corrected version, and put it back in the dropbox as "Sock-style_actuator_1.jpg"
