Re: pic: Team 1480 Kicker plumbing

I apologize, I should have added more explanation.

Our kicker operates by initially being latched back. The 60 psi storage "box" is one of the storage tanks. When the kicker is latched back the green arrows indicate the solenoid alignment, which allows the partially retracted cylinder to be precharged to 60 psi. To kick, the latch is released.

During retraction the solenoids are aligned to the red arrows.
Solenoid#2 is connected via brass fittings to the 60 psi storage and the kick cylinder. Solenoid #2 is added to conserve air that would otherwise be lost during retraction, minimizing recharge time for the next kick.
We may drop #2 if it looks like flow will be restricted too much.

Solenoid #3 is added to change kick distance by throttling the discharge rate. The "FAST" throttle valve is really schematic, since that won't be throttled at all. Note that on this valve inlet pressure is coming from the cylinder discharge. This is necessary in order to switch valve positions. (The solenoids don't actually switch the valves, they just open small pilot valves that allow air pressure to switch the valves).

The entire system is can be depressurized with a manual valve.
