Alasdair Ryan Posted June 1, 2014 Posted June 1, 2014 (edited) Well you may know me always building or messing around with something... So here is a test model using three servos and two pumps,I know it is crude but the point is to try and make a good responsive circuit using servo motors to control the valves while using another separate motor to supply with air. My pneumatic wheel loader worked very well but the mechanism I used in that took up a lot of space. In my crude test model below the servos are geared down using small and medium bevel gears,however there is still room for improvement. (sorry again for the bad video,one handed phone camera) I am aware there are different ways altogether to control pneumatic valves but I would like to try and use my four spare servo motors for something....

Bricktrain Posted June 1, 2014 Posted June 1, 2014 Personally I would try to offset the two pumps on different crank throws to reduce the pulsing pressure waves, although an air tank will help reduce that. If the servos were proportional they would be a lot better for controlling air valves, When my new spring loaded connectors arrive I will be experimenting with some valves myself. Quote

Don't worry I know all about that... When my new spring loaded connectors arrive I will be experimenting with some valves myself. Well I do have some of those my self but found them more suited for steering or PF switch controlling. Quote
