Spoiler PCU

HI

can anyone please tell me the working principle of Spoiler PCU ( Ground spoiler Power Control Unit). How it is actually extended and retracted.

I want to know how the flows are controlled.

Thanks
Ravi

You might actually get better results on this one from the mechanic community, but google is pretty amazing. I found the link below in no time. There are a few schematics in the file that might begin to address your question at least as regards the 737.

Good Luck!
