Try, cry, pry, wry... <- Except that in these instances, Y is the vowel. Unless you're playing Wheel of Fortune, where Ys are always counted as consonants and cost nothing to play.
Spelling-wise? Depends on what you mean by "vowel" and "word" – vowel isn't really a term for letters/spelling, it only really makes sense in a phonemic/phonetic context. So, phonetically? Yes – i.e. words that only have a rhotic in the nucleus like "curd" which is just [kɹ̩d] in many rhotic dialects like most American English, "and" is often pronounced [n̩], "can" can be [kn̩]~[kŋ̍], "full" can be pronounced [fʟ̩] in some dialects (includinɡ mine). You can also include paralinguistic words like "shh" [ʃ̩].
/ɚ/ in American (including Canadian) English as in "nurse", "curd", "certain", is usually labelled a "rhotacized vowel" in a phonemic context but it's more precisely described as an approximant (due to the fact that it has some constriction around the palato-velar area, uvula, glottis, molars, and/or labio-dental area, depending on which variety you speak). And as I said, "full" is pronounced with no vowel in certain varieties.
Those aren’t really English “words” though. There’s some old welsh in there which actually used W as a double U. And then some onomatopoeia, which while defined in some dictionaries, aren’t really words anymore than abbreviations like CIA or FCC are words.
According to the Cambridge English dictionary a word is simply "a single unit of language that has meaning and can be spoken or written", so acronyms and onomatopoeia are words as much as any other apparently. Maybe they would consider an acronym multiple units of language bound together though so not itself a word.
Fun fact: In Dutch 'vowels' is the same word as is used for 'streetstones' (klinkers), so if you ask this question in Dutch, the answer is 'dirtroad'. 😅
