i need to buy a pump that fits as many valves as possible.

AFAIK, there are three types: Woods (very rare), Presta (high pressure), and
Schraeder ('car type', low pressure).

Are you opening a bike shop? If not, why not buy tubes of one type only.
Having said that, some track pumps have a reversible head that fits Presta
and Schraeder type valves.
 
It's very unlikely you will come across a Woods valve, unless as Simon says
you are going into the bike business. If you are, you can get various track
pumps with "Smart" heads that fit all three.

You can get hand pumps that fit both Presta and Schreader, either by
swivelling the head or reversing the little insert.

Come on, tell us, why the need to fit so many types?

...As do some hand pumps. If you're using a pump with a connecting hose,
you'll need two adapters (one for Presta / Woods, one for Schraeder); if
you're using a direct-fit pump then you'll probably find that none are much
good on Woods valves, because they're too short for the pump to get much
grip. But, as I say, it should be possible to get such a pump that will work
on Schraeder & Presta by means of its reversible head (and which will get
you out of trouble with Woods).

Schraeder are cylindrical (i.e. of uniform section across their entire
length) and, as t'other Simon wrote, are identical to car valves. Presta are
thinner, and have two different diameter threads. They have a small nut
which unscrews to allow the valev to open.

Any decent bike shop should have these.

confusion on my part thats all. i found an old bike and i am restoring
it for love (and a little money) . from the other post i can see it
has schrader valves which is handy because ive just bought a cheapo
schrader pump on ebay. however i have also bought a spare tube which i
think may be presta. plus i am getting myself a bike and i may as well
be prepared for both standards.

Only two in common use; Schraeder and Presta. Most pumps can work with both.

Three, in ascending order of popularity:

Woods (originally British - now so rare that you can afford to ignore
it)
Presta (originally French - primarily used on road bikes and very
upmarket mountain bikes)
Shraeder (Originally USAian - everything else, including car tyres)

You need one pump on each bike, to whit a Blackburn Airstick AS-1[1],
fits Shraeder and Presta valves (but you have to unscrew the head and
turn the adaptor round to change valve types, which is a hassle at the
road side), and one track pump at home. Can't particularly recommend a
track pump because mine is slightly not very good, but I hear the
Topeak Joe Blow may be the one to go for.

My advice would be to standardise on one type of valve on all your
bikes. Mine are all Presta so I don't have to mess about with changing
adaptors.

If you ever want to buy a another new pump, most good modern ones fit both
presta and shrader valves, the two most popular types.

You might want to choose the Velox cloth type rim tape instead of the
soft plastic alternative. Once you get past certain pressures the
plastic type can cause punctures, cloth tape won't give you this
problem.

If you are still in any doubt, click here:

and scroll down to the entry for Presta where it has pictures of all
three types.

I have one of those. The only thing that worries me is the handle feels a
bit flimsy. Otherwise it is good value for money..

I just got one of these from Wiggle, and it's excellent. I
don't know how I managed without one. Got my 700x28s up to
100psi very quickly and easily.

It's got a double pump head arrangement, so no faffing about
if you've got Schreader and Presta to deal with, and it also has
adaptors for footballs and rubber rings etc!
