Pressure control valve

摘要: An improved pressure control valve which provides equal damping force in both directions of movement the spool and also negative feedback to partially negate fast transients leading instability. The includes a body having an inlet chamber enlarged adjacent chamber. A is received within chambers, first portion second radially outwardly extending disposed As shifted open position fluid will be expelled from through orifice, as returns towards its closed orifices cross-sectional areas proportionate volume being so that obtained either direction spool. provided with orifice passageway permits communication whereby transient peaks may transmitted provide for feedback.
