Kolvslidsventil

En kolvslidsventil (eller kolvventil) är enkelt uttryckt en kolv med ett antal hål, som ljusteras upp och ner i en cylinder. Cylindern, oftast ett foder monterat i ventilhuset, har hål (genomsläpp) som ligger passade mot ventilhusets anslutningshål. Genom att justera kolven med ventilspindeln, bildas en väg för mediat genom ventilen.
