how a autococker works

Experience is the best teacher...

On this page I'll include some tips and tricks I've learned about autocockers 

Please feel free to contribute your own tips - I'll post the best ones so everyone can see them.

heres somthing to help you understand how a cocker works.
Assuming your gun is properly timed, and everything is perfect and you have a Stock mechanical autocoker and operating pressure is around 350psi.

Alright Air from the Air Source (Nitro/CO2) goes through the Inline regulator which controls the input pressure which is set to 350psi. After the air goes from the regulator it goes through the vertical ASA and into the body, now from there the AIR goes 2 ways through the valve and through the front pneumatics. Lets go into the Front pneumatics first to get a better understanding of how everything works together. There is another regulator that air has to go through which is called the LPR (Low pressure regulator) what this regulator does is brings the operating pressure down to about 40-70psi depending on the Ram you are using. After the regulator has dropped the pressure from 350psi to say 55psi it goes into the 3way. Now the 3way has 3barbs the middle one is the one connected to the LPR. Inside the 3way is a shaft with either 2 or 3 orings depding on the 3way (ie. most 3ways like Belsales Hollow Point, CT-3way, Freeflow Bullet have 2o-ring shaft, Shocktech Bomb, DYE P.M.P have a shaft with 3o-rings usually these 3oring 3ways have to have the front pneumatics hoses backwards than a normal 2oring 3way.) you have unless you have the GForce Paintball Gemini system which is another story. Anyways these orings prevent leakage and play a crucial part to the function of the ram and cocking system. When the shaft inside the 3way are in a certain position the air from the LPR go into the front barb or back barb ( this depends if your using a Hinge or Slider frame and 3way) assuming I havent lost you yet the shaft directs the air from the LPR to a section of the ram which will either push or pull the ram in the open or close position. ok now that we know what the front pneumatics do we can get more in depth into the firing sequence and assembly. Now as for firing sequence we gotta look at the Trigger frame now. The trigger frame has A trigger either hinged or Slider, a sear, screws and springs. There is a rod called the timing rod and coupler which connect to the shaft in the 3way, this is what controls when the air is redirected to the certain part of the ram to open or close it. Oh yea dont forget the Ram is connected to the Pump Arm which is connected to the Back Block which is connected to the bolt. When you look at the trigger frame you'll notice a hole or slot near the top front portion of the trigger frame this is where the timing rod goes. As your pulling the trigger it will move the timing rod either forward or backwards (Forward if your using a hinge, backwards if your using a slider) what it does is inside the 3way the oring holding the air inside is moved to one of the other barbs which pushes the air to the ram making it move back and cocking the gun, now your gun is in the open bolt position. Let go of the trigger and the shaft goes back to its normal position which redirects the air to the ram which puts everything back to the closed position, if this is done a ball is now loaded and the bolt is closed and the gun is cocked. Just so you know the cocking rod which was pulled back by the Back Block which was pushed back by the ram is connected tiothe hammer assembly. Now your gun is cocked and the cocking rod is pulled back. Now if you do the firing sequence again by pulling the trigger what happens is the sear being pulled down which lets the hammer go hitting the valve stem which opens the valve allowing air to travel up into and down the bolt which is what propels the ball and as you continue to pull back the trigger the shaft again in the 3way activates causing the ram to go back cocking everything allowing a ball to drop and ready to fire again. This is the basic function of a mechanical Autococker same thing happens to a Electro cocker but instead of the 3way shaft and timing rod everything is controlled by the Solenoid. I hope this helps you and not confuse you more of the functions of a autococker. Here are some annimations on how everything works together.

The Autococker has a very sophisticated cocking mechanism. The easiest way to understand it is to think of how a pump marker works. You pump, it loads, you fire, repeat. This is what an Autococker does. You pull back the block to cock it before you gas it up, a paintball drops down from the feed tube into the chamber. Then you gas it up, the trigger is in the forward position. The back block goes forward and is ready to fire. Now as you pull the trigger a couple of things happen. The first is the trigger moves the sear and that lets go of the hammer and the marker fires. As you continue to move the trigger back it causes the 4 way valve to redirect air to the front of the ram. This air causes the ram to push the back block into the same position as when you cocked it by hand before you gassed it up. When you let go of the trigger it causes the 4 way valve to supply air to the back of the ram, thus closing the bolt. The sear has now returned to its starting position holding the hammer and the marker is once again ready to fire. I took this picture from the WORR Games web site, it takes a minute to load but watch it carefully and try to follow everything that is going on in small parts.
