Q:Dr says I have a leaking heart valve but not which valve.?
How the Heart Valves Work At the start of each heartbeat, blood returning from the body and the lungs fills the atria (the heart's two upper chambers). The mitral and tricuspid valves are located at the bottom of these chambers. As the blood builds up in the atria, these valves open to allow blood to flow into the ventricles (the heart's two lower chambers). After a brief delay, as the ventricles begin to contract, the mitral and tricuspid valves shut tightly. This stops blood from flowing backward into the atria. As the ventricles contract, they pump blood through the pulmonary and aortic valves. The pulmonary valve opens to allow blood to flow from the right ventricle into the pulmonary artery. This artery carries blood to the lungs to get oxygen. At the same time, the aortic valve opens to allow blood to flow from the left ventricle into the aorta. The aorta carries oxygen-rich blood to the body. As the contraction ends, the pulmonary and aortic valves shut tightly. This stops blood from flowing backward into the ventricles.
Q:Why was the fuel selector valve in the OFF position when JFK JR,S aircraft was found?
Not to take away from JFK jr's piloting skills but the possibility exists that he failed to check to see if the fuel valve was on in the first place. I do not know how far along in the flight he was, but a typical piston engine plane can get you up and on your way with the fuel that is in the fuel system. Why I know this, my flight instructor while training one of his students died in a forced landing due to engine failure because the fuel valve was not turned on. My flight instructor would allow his students to perform the preflight on there on, of course after many hours of dual training. The plane was a piper four place, it made it to about 400 feet agl before the engine stalled from fuel starvation. The irony of his death was from complications on the operating table from a broken ankle and a blood clot that broke loose. Checking for the on position of the fuel valve is on the check list. During emergency landing procedures, one of the functions is to turn the fuel valve off to reduce the possibily of fire. This doesn't answer the question but is a possibility unless of course he was well into his flight before the accident, in which case he probably moved the fuel valve to the off position following emergency procedures.
Q:Trouble inflating presta valve?
Did you take the adapter off? It is only intended to fill the tire, you take it off and close the valve.
Q:Ticking sound on 700 Grizzly...Valves?
They are correct. Well almost. The Rockers are what can be adjusted. They are too far away from the valve and are starting to hammer on them instead of just moving them. You will not cause immediate damage by riding it but you could wear out the rocker completely and drop a valve into the engine which would be very costly. Best to get it repaired soon. Make sure they install new rockers and springs. The main cause for this is poor oil maintenance or poor grade of oil being used. Always use a GOOD synthetic oil and your motor will last 10 times as long
Q:96 saturn sl1 EGR Valve...?
There is a device called the transducer that connects to the EGR system via vac lines that doe's have a electronic plug on it that could show up under codes as if the EGR valve is faulty but isn't.If the EGR valve has a electronic plug on it then it could be that it's faulty. Hope that helps and best of luck.By the way I ran into that same problem and it was the transducer.Keep in mind that at the big do it yourself auto wreckers you should be able to find several of either of those parts.
Q:Euphonium problem, valves?
There are several possibilities. You may have buildup on either the valve or the casing. Cleaning it thoroughly should normally remove it, but every once in a Blue Moon it pays to take it in and have it professionally cleaned. They can inspect it at the same time and tell you if you have a bend or a ding in the casing. Sometimes they are really hard to spot, especially if they are hidden in one of the crevices of the detail work. A really good repair person can stick a scope down there and tell you if you have some kind of blockage in just a few minutes. The only way to really clean inside the casing yourself is to get a good bottle brush that fits inside with just a little bit of resistance. You should really get someone to show you how to do it the first time because you don't want to go scraping up the insides. There is one other possibility that is kind of rare. Sometimes you get some gunk up under the valve button and it sticks when you push it down. You should normally be able to see this just by looking underneath however. Best of luck and I hope you find your sticking point and are able to set it free.
Q:Engine valve leaking?
Valve cover? Generally a pretty minor job. Exhaust or intake valve? Generally a pretty extensive project.
Q:I am getting a valve job...?
The valve job may not solve the engine problems /condition.Consult your service centre and ensure you take their advice!
Q:i wanted to know what is the actual difference between check valve (non return valve) and globe valve?
A check valve stops water from going back through the water line . A globe valve is a type of valve that uses a ball shaped device with a series of holes which regulate water flow , normally found in household water supplies. The other type of valve is a gate valve, which is used where a larger flow is regulated, like in most commercial applications.
Q:How to adjust lawn mower valves?
when a valve is closed there should be a gap under the valve stem and push rod that's the adjustment, when a Valve is open the push rod is against the valve end so you cant adjust it while its open i would set them at 10,thousands to allow for heat expansion
