Retentor de mola
A loja MWM vende um retentor de mola idêntico ao da imagem fornecida no catalogo da Eaton. Me parece então que se trata de um retentor que segura a mola da bomba de óleo e que quando está gasto deixa a mola escapar.

Rolete com mola, "legs" quanto a mim são "rodas" - seria a minha sugestão, mas com pouca certeza.
