Abstract

APARELHO PARA A DETERMINAçãO DE POSIçãO DE PISTãO LIVRE E APARELHO PARA O CONTROLE DE POSIçãO DE PISTãO LIVRE. A presente invenção refere-se a um aparelho para a determinação de posição de um pistão livre usado, por exemplo, como um compressor hidráulico, sem nenhuma ligação mecânica com o eixo de manivela e um aparelho para o controle de movimento alternativo do pistão livre que são apresentados. Um aparelho para a determinação de posição de posição de pistão livre compreende um sensor magnético disposto em uma caixa contendo um pistão livre, e um imã disposto sobre o pistão livre. O sensor de imã gera um trem de pulso quando o imã é posicionado dentro de uma distância predeterminada do sensor magnético. O tempo do pistão é computado com base na duração do pulso, e o deslocamento da posição de pistão média da posição média designada é computado com base no intervalo do pulso.
