Help with air con compressor
If anyone has an air con compressor of their donor car that they want to get rid of, I need one. I'm looking for a small car one with a V belt
pulley, lighter the better. No I havent got a posh kit car ive got one of these
 
Description
I need it to drive the air operated bonnet opening and closing (all locost honest). Ive tried tyre compressors and there useless also tried fridge
compressors but it means extra kit to get 240V. Fleabay and scrappers seem to want an arm and a leg for these items, so has anyone got something
locost that fits the bill. Short vid of bonnet opening here

Can't help with the compressor I'm afraid, I'm just being curious 
Could something like a linear actuator
Linky , but in a 12v version be used instead of air power?

do you not have an accumulator to lift it
i would of thought a small compressor like the off-road brigade for air lock diffs
would charge a small accumulator easily enough to lift that bonnet.
your rams dont seem large and i guess the bonnet is light .
i,ve seen old fire extinguishers used as accumulators/reservoirs with a small regulator in-line and a solenoid valve that
would be a fairly simple fit up

rangerover/discovery suspension compressor? and as above a small reservoir so a little calor gas bottle. Use a LPG electric valve to seal to cap the
reservoir so the pump just tops this up.

Hi guys thanks for the input, i have a small accumulator about 6 litres already fitted, and the system runs at about 125 psi. The bonnet is quite
heavy on par with a large tin top I would have thought. I have searched the web etc and several off road sites have used small air con compressors and
have got really good results from this, but needs must and i need to go the locost route.

I think I have one from a Supra. You may have to change the pulley (not sure) but you're welcome to it if you can collect.

Flibble Nice thought and it would certainly be powerful enough, the problem is the bonnet needs to be lifted slightly at the back then slid forward
before the bonnet actually tilts. Very convoluted I know and it took me a long time to work out the timing and actuation of the various rams 5 in
total plus 4 micro switches (there more for safety ie you cant operate the bonnet if it is locked closed) So it would need a complete rebuild (not
locost) but it would negate the need for a compressor, I can see where your coming from, anyway nice thought and thanks for your input.

what about hydraulic? a roof set up from a peugeot can be had pretty cheap off ebay i think, and would be less 'springy' when it opens up
i think.

The springyness is due to me not having set up the dampening at the end of the rams travel yet, also problem as above with the opening action.
Thanks

Following on from our U2U's, here are a couple of pics of the unit I have. (It may be a power steering unit?)
