jorgeopesi Posted October 7, 2013 Posted October 7, 2013 Someone have seen something like that?, it works very very well and you can easy put a pump and be an autovalve. http://www.youtube.com/watch?v=PNOyIDnYSKk&feature=youtu.be Quote
Junpei Posted October 7, 2013 Posted October 7, 2013 Yes I have seen one, in fact I just built one with an m-motor. That's a very compact one though, I never thought about using the double split connector. Quote
jantjeuh Posted October 7, 2013 Posted October 7, 2013 (edited) That looks like a good solution! Some autovalves use small 8 tooth gears on top of the valve switch, in combination with a worm gear, to switch the valve lever, but these gears might pop off unless you happen to own tight ones. This solution works in all cases. Thanks for posting this. Edited October 7, 2013 by jantjeuh Quote
jorgeopesi Posted October 7, 2013 Author Posted October 7, 2013 If you don´t need the autovalve you can rotate the triangule liftarms making more compact the construction. Quote
KirTech LAB Posted October 7, 2013 Posted October 7, 2013 New valves require more power to switching, than white gear can supply - it simply slips. So with new valves this system don't working! Quote
delithug Posted October 7, 2013 Posted October 7, 2013 Do they still make this style of valve? I've taken a bit of a break from LEGO the last couple years but as I recall, these were scarce and expensive on BL as they were out of production. Quote
jantjeuh Posted October 7, 2013 Posted October 7, 2013 TLG stopped producing valves with studs in 2004, but you can still quite easily buy them on BL (though not cheap). Quote
Milan Posted October 7, 2013 Posted October 7, 2013 There are 3 types of white gears, with different resistance, maybe the strongest one can pull the lever of the switch. Quote
MrTekneex Posted October 7, 2013 Posted October 7, 2013 I do not like for two reasons: first, because as has already been said is an old valve, much more soft to be switched than the new ones. Second because I do not like the fact that, by applying an m-motor and a pump, the gear frictioned is always under stress, it would ruin in a short time (IMHO). Quote
Lipko Posted October 7, 2013 Posted October 7, 2013 I wouldn't rely on a continuously sliding friction gear. I don't know how long the gear would work as a friction gear. Quote

jorgeopesi Posted October 7, 2013 Author Posted October 7, 2013 You are right, my first intention was only find a small swith, in fact I am using it with a normal 24th gear. Quote
