Actually, Harregarre, "y" is sometimes considered to be a vowel. But apart from the words you mentioned, and probably many others, in English there are no words without vowels.

Krk is the name of the island in Croatia :) http://www.google.lt/aclk?sa=l&ai=B-5i5lpyeSMSCHI2S0QWdsdz8A9vm0jTjyoikBKvKqxewzAsIABABGAEoAjgAUJy-o_L7_____wFgubvtBKAB06qc_gPIAQGAAgGpAiodr27jcLk-yAKPwI8B2QMXwh8zcaJZWw&sig=AGiWqtzxrWFFraodmtodVAGrQymyOQY4bg&q=http://www.adriatica.net/mk/l__4r4ji3l3l3p3kh4r5ji3l__.htm

The "y" is not considered a vowel, so in fact there are many. Cry, by, sky, why, wry, gym, crypt, hymn, lynx, myth, glyph, tryst, nymph, Gypsy, pygmy, myrrh, etc.
