Q:in a blowback paintball gun, what does the valve do & how does it work?
The majority of blowback paintball guns use a pin valve, which is opened when struck by the hammer. The hammer is held in the back position, with the spring compressed, by a sear. When the trigger is pulled, the hammer is propelled forward by the spring, into the valve. These sorts of markers generally use a “stacked tube” design, in which the valve and hammer is contained in the lower tube, while the bolt, which is connected to the hammer, is in the upper tube. The gas released by the valve is then simultaneously channeled up to the bolt to fire the paintball, and back to push the hammer back into the ****** position (hence the name “blowback”). Poppet valves are usually easy to replace and require little, if any, maintenance. The downside to this design, however, is its high operating pressure, which leads to a larger recoil and arguably less accuracy. The valve is usually designed to accommodate a specific operating pressure. Low pressure valves provide quieter operation and increased gas efficiency when tuned properly. However, excessively low pressure can decrease gas efficiency as dramatically as excessively high pressure. The volume of gas released by the valve directly affects the paintball's velocity. The velocity adjuster alters the pretension on the hammer spring which controls how long the pin valve is held open for, or more correctly how much gas must be released to push it back into the ****** position. EDIT - Sorry but wouldn't even know where to start on designing a valve.
Q:how can multi valve prolapse affect me? (13 year old female)?
Do you mean Mitral valve prolapse? The mitral valve helps blood on the left side of the heart flow in one direction. It closes to keep blood from moving backwards when the heart beats (contracts). Mitral valve prolapse is the term used when the valve does not close properly. It can be caused by many different things. Most people have no symptoms, but some people have chest pain, a rapid pulse, awareness of heartbeats, migraine headaches, fatigue, and dizziness. In a small number of cases, the prolapse can cause blood to leak backwards. This is called mitral regurgitation. Mitral valves that are structurally abnormal can raise the risk for bacterial infection. Some forms of mitral valve prolapse seem to be passed down through families (inherited). Mitral valve prolapse has been associated with other genetic disorders.
Q:What are these valves on top of my compressor?
The valves are probably one way check valves and the line is called the discharge line. The valves could also be un-loader valves that release the head pressure when the compressor shuts off. For parts just google your compressor brand and model for parts dealers.
Q:what about blow-off valves?
Blow off valve or dump valves are used on cars with large turbos. Their function is to keep the turbo spinning during gear changes or on the over-run. Because they are driven by the exhaust gas the turbo has a lag (delay), it takes time so spin up or slow down compared to the engine speed. The bigger the turbo in relation to the engine, the bigger the lag. By dumping the excess pressure it keeps the turbo spinning reducing the lag when you get back on the throttle. It will have no effect on power on small turbos so all these boy racers you see in civics have wasted their time and money. PS The noise it makes, I think is PTCHOO!
Q:What is trumpet valve oil made of?
Valve oils use proprietary formulas so it is unlikely you will be able to find out an exact composition. The basic ingredients of petroleum (as opposed to synthetic) valve oils are light machine oil (kerosene), mineral spirits and fragrance.
Q:Unplugged Idle Air Control Valve?
Go to your local library, ask if they can get you the *factory* GM wiring diagram and service manual for your specific year/vehicle. They have a troubleshooting section that is usually quite good, with easy to follow flow charts. IAC is tied into the ECM in the way it handles air when you aren't using the gas...decelerating, stopping, when you start the vehicle (and different depending on whether the engine is cold/hot), etc. It will be stuck in one position now. When it starts to cause problems, you'll see them manifest in the conditions I describe above. If there truly no issues with the way it runs, then don't worry about it until you start to have problems. It's not going to destroy the motor without it. Not my cup of tea to know there is a problem, and ignore it, but then again, I'm me. You can rest assured though, if it were unnecessary, and saved GM one penny to not give it to you, they would not have installed it in the first place. :)
Q:how to intall a new shut off valve?
its called 'an angle-stop' and if you have copper, its sweated on or compression fit. if its compression, get a crescent wrench and take it off at both pipes and take to store and replace same ones, but better quality. don't forget to shut off the water to the house outside! if its sweated on, you need to have someone that knows how to copper weld to do it for you. if its galvanized pipe, unscrew it like 1st and proceed with another like item or switch to copper with a dialectic fitting between both.
Q:could i have a Bad EGR Valve?
The EGR must be closed at idle and open as you cross quicker. If your EGR have been caught closed, it could don't have any final result on driveability. If your EGR is caught open, probabilities are it in most cases may not idle for lengthy earlier than dieing. I could blank the MAF sensor placed simply after the air filter out. Use BrakeClean spray. You did not say whatever approximately the gas injectors. I could placed an injector cleanser within the tank (it would possibly not support however its inexpensive than exchanging them). You would dispose of the spark plugs and notice if any seem discolored indicating a persistant pass over. This would point out the cylinder or cylinders with disorders similar to plugged injector, dangerous coil, something.
Q:effects of a bypass valve on a car?
bypass valves are for cars with forced induction IEturbocharger,supercharger it allows the air that would normally be expelled into the atmosphere blow off valve and instead putting it back into the intake which helps with less lag in building boost again. If your car is not turboed or supercharged then forget it.
Q:EGR Valve 2nd Question please...?
What is it that you are trying to do? Your question is sort of vague.
