Low pressure hydraulics using engine oil pressure
Low pressure hydraulics using engine oil pressure
(OP)
I have an idea that I'm trying to see if it is practical to implement cheaply with off the shelf components or semi-custom components (i.e. custom cylinder stroke). Don't want to get into too much detail on the application, but the fluid power will come from engine oil with a minimum operating pressure of 20-25 psi and max around 100 psi. Oil temps can be as high as 250F. It will be stroking a hydraulic cylinder. The cylinder stroke will be very short stroke say 1/2"-1" max. Flow rates will be low, maybe 5 gpm max. Cylinder will have to be controlled my a manual valve, spring centered, 4 way, 3 position, with P blocked and A&B tied to tank. I can't seem to find anything designed for low pressure, inexpensive hydraulic systems. I can't afford the cost or weight of typical 3000 psi hydraulic components. Are there any low pressure hydraulic component manufacturers? Are there any pneumatic cylinders and/or controls that can be used with oil instead?

If you're going to bring potentially hot oil through the firewall, with 'cheap' plumbing, on someone else's vehicle, you will need a product liability lawyer eventually, so get one lined up soon.
Have you looked at the hydraulics for convertible tops?
