Q:What prevents the valves in the heart from being pushed backwards?
the heart valves maintain the unidirectional flow of blood in the heart by opening and closing depending on the difference in pressure on each side. (wiki) So I would assume that the pressure of blood flow is what prevents the valve from pushing backwards. ALSO Atrioventricular valves These are small valves that prevent backflow from the ventricles into the atrium during systole. They are anchored to the wall of the ventricle by chordae tendineae, which prevent the valve from inverting. The chordae tendineae are attached to papillary muscles that cause tension to better hold the valve. Together, the papillary muscles and the chordae tendineae are known as the subvalvular apparatus. The function of the subvalvular apparatus is to keep the valves from prolapsing into the atria when they close. The subvalvular apparatus have no effect on the opening and closure of the valves, however. This is caused entirely by the pressure gradient across the valve.
Q:How does a thermal bypass valve work?

Q:why would oil be leaking from the blow off valve?
It is turbo rebuild time sorry The internal shaft seal has gone bad and if you don't act fast the impeller and shaft might not be able to be saved. Also if you don't heed that warning the impellers can strike the turbo housing and pieces can be blown into the engine.
Q:French Horn Valve Compression?
If you like how it plays you might just wish to leave it alone. Anything you do is going to change the way it plays, perhaps to something you don't like. Check compression by pulling the valve slide part way out, wait a second or two and then push the key, as the air fills up the partial vacuum cause by pulling the slide you should hear a nice thunk. If there is no noise when you push the valve the air is leaking around the valve and that's bad compression. Another way to check is just slowly withdraw the valve slide. It should get harder as you pull due to the vacuum, if it comes all the way out it should pop.
Q:Where can i find a three-way air pressure valve?
You might have to register on the site to order online. It is free. You can call them and order the catalog. It is free also. Hope this helps Email me if you want me to look it up in my catalog. Don't break any windows. Wingman
Q:what is the pupose of valves in the industry/?
Valves are used to stop/start or control the flow of liquids or gases in pipes. There are many many kinds of valves, so if you want info on a specific type, just list that.
Q:Mitral valve prolapse have impression on lifetime?
Mitral valve prolapse (MVP) is the most common heart defect in population. The prevalence of MVP is about 0.6–2.5%. The occurrence increases with age, and the highest is in young woman. MVP is diagnosed by transthoracic echocardiography when displacement of mitral valve leaflet(s) above the annulus into the left atrium during a systole is present (Fig. 1). The clinical symptoms of the disease are connected with instability of the autonomic nervous system. Fig. 1 Two-dimensional echocardiographic long axis parasternal view of mitral valve prolapse. MV mitral valve, LV left ventricle, LA left atrium, RV right ventricle, Ao aorta Such a large population of patients becomes a problem of social significance, and it is extremely important to determine the influence of MVP as a chronic disease on patients. That is why our trial to evaluate the health-related quality of life (HRQOL) in children with MVP was undertaken. There are many publications concerning MVP in adult patients, but no study on their quality of life has been found. The literature concerning HRQOL of children with heart defects is not very extensive; the authors analyzed the problem of patients with serious conditions, such as hypoplastic left heart syndrome, transposition of the great arteries, pulmonary atresia, tetralogy of Fallot and non-complex heart defects, like ventricular or atrial septal defect [1–3]. The aim of our study was to evaluate the quality of life of children with MVP and the impact of clinical symptoms on HRQOL. You will detailed information on the link given in sources, as it is long topic.
Q:removeing the driver side valve cover?
valves don't knock and you can't get to them through the inlet manifold if it's the lifter you may be able to get it by taking the valve cover off but even then you sometimes can't and have to remove the camshaft
Q:Leaky Toilet shutoff valve....?
I'M plumber : sound like just need to replace the gasket in both ends of the hoses,some times this get worn or not tide enough
Q:Why do some baritones have 3 valves and others have 4?
The forth valve on the baritone is the same as the trigger on a trombone - it lowers the pitch 2 1/2 tones to extend the range downward, to assist in improving intonation, and to solve so tricky fingering problems. You can learn baritone quite easy, if you relate what you know on the trombone to it. Here is a quick lesson on valve playing. Trombone position Baritone valves 1 Open 2 2 3 1 4 1 2 5 2 3 6 1 3 7 1, 2 3 Trigger 4 On high F#, you must play 2 3 On High G, you must play 1 2 Good Luck! It is a great and wonderful instrument to learn, and will help you trombone playing, too!
