Not alone thinked about it a while back,currently studing fliud power and in the fluid power industry (...) Lego pneumatic cannot be used for hydraulic's period! Nor will there be such a thing put out by lego there in the toy industry not heavy (...) (20 years ago, 8-Apr-04, to lugnet.technic)

(...) Not necessarily. Assuming both cylinders are the same size, a full pump cylinder stroke will only result in a full working cylinder stroke if the working cylinder doesn't have significantly more resistance than the pump cylinder. If the (...) (20 years ago, 7-Apr-04, to lugnet.technic)

(...) One key thing about hydraulics has always been "avoid leaks". To switch the fluid, just invent something I've wished for for years - the reverser switch. This switch has four ports, used in opposing pairs. Clockwise in a circle they would be (...) (20 years ago, 7-Apr-04, to lugnet.technic)

(...) Yes, eventually that will happen. The tricky part is actually buying the stamp. :) I'm a little worried that the ink will drip out of the ink pad since it's inverted but I'll just have to cross that bridge when I get to it.

(...) Well one solution to that problem is to position all the switches above a "hydraulic fluid catchment area", however I still think it would be prone to spillage ;) ROSCO (20 years ago, 6-Apr-04, to lugnet.technic)

(...) The simplest reason is that when the switch is flipped to one side, the other port is released to the atmosphere. This means that your hydraulic fluid would spill all over the floor. Figure out how to eliminate the free release (hint, only (...) (20 years ago, 6-Apr-04, to lugnet.technic)
