Q:Valve Replacement Surgery?! ?
Valve replacements actually have very low morality rates like 1-2%. There are always risk's with surgery though, such as blood clots or irregular heart rate. The recovery in the hospital is generally 5-7 days, and then it can take anywhere from 8 weeks to a year to feel recovered.
Q:In a car, whats a valve/cylinder?
There are intake valves and exhaust valves. On the intake side, the intake valve opens which lets the fuel/air mixture into the combusion chamber. At some point (measured in degrees of crank rotation) the intake valve closes, the air/fuel mixture is compressed and ignited by the spark plug. Then the spent mixture exits the cylinder when the exhaust valve opens. Valve configuration varies somewhat, but regardless of how many valves there are there will always be at least one intake and one exhaust valve. Some cylinder heads have 2 intake and 2 exhaust valves which is what is described as the 4-valve per cylinder setup. Regarding Car Cylinders, the answerer says Cylinders in a car engine are pretty much like rowers in a boat. But they are not. Rowers always row in synch with each other. Cylinders are made to be out-of-sync for smoother operation. The more cylinders you have, the smoother the engine runs. Compare a 1-cylinder minibike with a 4-cylinder motorcycle (both air-cooled), or a 4-cylinder to an eight... big difference in smoothness.
Q:***10 points**** Which set of valves closes when the ventricles contract and relax?
Atrioventricular valves close when it relaxes and the lunar valves close when it contracts
Q:bicuspid aortic valve information?
definite you will possibly have constantly had this, it fairly is a few thing you have been born with. a typical aortic valve is tricuspid, it fairly is it has 3 ultimate flaps, yet a bicuspid valve basically has 2 flaps. now and back those bicuspid valves supply no problems, yet in some people they could bring about heart murmur later in existence ( usually on your 30s or 40s ) via fact they permit a sprint blood to leak back the incorrect way while they are closed. If this gets intense sufficient, you are able to need surgical operation to in high-quality condition a man made valve. it fairly is exceedingly usual those days and not some thing to rigidity approximately.
Q:pro's and con's of mechanical valve vs tissue valve...?
I okorder.com/... okorder.com and I will answer from my personal experience. The only difference in her surgery and mine is that they are replacing her aortic valve and I had my mitral valve replaced. Oh, I forgot to add about costs, depends upon State you live in. Here in NC my surgery in 2003 was about $60,000 to $70,000 (but I did have insurance and I only ended up having to pay $2,500. I was in the hospital for 9 days also.
Q:Water leaking from stop valve?
It's not the packing nut seal since that only seals the stem which is attached to the handle. There is an inner washer attached to that stem which shuts off the water, this is probably worn and needs replacement. Do not attempt to change this valve, leave it to a professional because it's not an easy thing to do, unless you're good at soldering. Shut off the main water supply that services the whole house. Also note: If you don't have wood behind the sheet rock from your existing vanity, you'll be in trouble, because the Pedestal must be bolted to the wall to be secure otherwise it's a safety hazard.
Q:1981 xs650 yamaha valves?
Remove both spark plugs. Remove all 4 valve inspection covers. Remove the Generator cover (L crankcase cover, round, 2 screws). It doesn't matter which side you start on. Turn the crankshaft in the direction the engine runs. Depending on which cylinder you're working on, watch that intake valve. When the rocker arm pushes it down, then comes back up, the piston is then moving up on the compression stroke. Continue turning until the piston is at top dead center. You can line up the T mark on the flywheel with the pointer, or look into the spark plug hole to see when the piston is at the top. Adjust the valve clearance for the intake exhaust valves on that cylinder. Repeat for the 2nd cylinder.
Q:difference between swing type check valve and non return valve?
Non-return valve is another name for check valve. A swing check valve is just one type of check valve that uses a hinged gate to allow flow in only one direction. It operates sort of like a one-way fence gate, that you can open by pushing from one side, but you cannot open by pushing on the other side. Other types of check valves: Diaphragm, Ball, Lift, Duckbill. (:-o)
Q:Question about variable valve timing?
Valve timing is a compromise. You can optimize valve timing for a certain RPM, but it will be wrong for every other rpm. Advancing a cam helps bottom end, and retarding a cam helps top end. Actually changing duration and lift is more difficult, but can be done, and IS being done. The benefit is to widen the torque curve, helping both power and economy
Q:Function of reed valves?
there are quite a few types,reeds/reed valve/disc valve..all 2 strokes have some sort of reed system...idea is that fuel is sucked past the reeds,these then close letting the fuel travel where it needs to go,opening when its time to suck fuel in....and so on
