For several occasions we have been featuring here diverse proposed designs for Electric Valves  and Auto-Valves/Pumps [2, 3, 4, 5] as developed by different builders.
Today I'd like to highlight another recent design for an Auto-Pump by Jernej Krmelj (Zblj), which I found very compact and useful.
Please notice the render on the left does not use the actual pneumatic switch but a brick base representation of it, as it is likely not available at LDD.
It seems to me, probably the most lean design for an Auto-Pump that I've seen so far. What do you think of this concept?
Please avoid sending requests to post specific models on this TBs section.
We understand some of you would enjoy to see your creations featured here, but please understand that because only one video gets highlighted per week, it is impossible to accommodate all the great MOCs continuously build by the Technic builders out there. They simply won't fit all and that's also not the purpose of this blog (see the header statement).
Many of your MOCs are scanned anyway and listed for later publication when they do not fit immediately. However some remain in the backlog queue just for too long and eventually loose the relevance or the publication opportunity window. As a rule of thumb, we also avoid publishing MOCs that have been featured by their authors or other fans at some other great web places dedicated to the Technic community out there. It doesn't mean that occasionally some won't get published here anyway.
Thanks for your understanding!
