Abstract

"CONTROLE DE DESVIO DE POSIçãO DE PISTãO, E, DISPOSITIVO DE PISTãO LIVRE". Um controle de desvio de posição de pistão (110) para um dispositivo de pistão livre (112). O controle inclui uma passagem conectando volumes internos do dispositivo, a passagem (122) sendo substancialmente mais curta do que um comprimento de onda acústica do dispositivo; e uma válvula de retenção (124) na passagem para controlar a comunicação fluida entre os volumes internos, a válvula de retenção tendo uma pressão de abertura não menor do que, aproximadamente, 20% de um diferencial de pressão máximo do dispositivo a um curso máximo. O controle é passivo, não requer controle ativo uma vez em serviço, provê baixa susceptibilidade a dano ou obstrução, e é amigável a ajuste ou reparo, caso necessário. Em adição, o controle é pequeno e barato, e funciona por toda a faixa operacional de um dispositivo de pistão livre que ele suporta. Um dispositivo de pistão livre correlato, incluindo o controle de desvio de posição de pistão, é também provido.
