What is this part called ?

[Penny Whistle]

Apologies that it's not car-related, but I'm sure that PH can answer this simple question. I want to call it a tappet, but that usually sits on the camshaft lobe (?), whereas this sits on the valve stem, underneath the rocker arm. Is it a bucket tappet ? It's 7.5mm thick, 14mm o/d with a 8mm dia recess to fit over the valve. For context, it's from a Kubota 3-cylinder diesel engine (D1402 model) in a small 3-tonne digger. Bonus points if anyone can find me a source to replace the three which I stupidly lost on a gravel yard when removing the head.

Looks like these are breaking one so might be worth a call to see if they've still got them:

ETA Appears they are called 'valve caps'

Valve caps is indeed what they are called.
