Title (EN) CONTROL VALVE WITH BYPASS MEANS
(FR) SOUPAPE DE COMMANDE AVEC BY-PASS
Abstract: front page image
(EN)A valve (10) controls fluid flow to a fluid jack (12) by movement of a single valve spool (38) to a first position. A check valve (15) and bypass valve (16) cooperate to pass fluid exhausted from the fluid jack (12) to a tank (13) bypassing the single valve spool (38). Movement of the bypass valve (16) is controlled by developing a controlled pressure drop between the fluid in the fluid jack (12) and the fluid between the check valve (15) and the single valve spool (38) in response to the valve spool (38) being moved to a second position.
(FR)Une soupape (10) commande le debit d"un fluide dans un verin hydraulique (12) par mouvement d"un seul piston de soupape (38) en une premiere position. Une soupape de retenue (15) et une soupape by-pass (16) cooperent pour faire passer le fluide evacue du verin hydraulique (12) dans un reservoir (13) en by-passant le piston de soupape simple (38). Le mouvement de la soupape by-pass (16) est commande par une baisse de pression controlee entre le fluide se trouvant dans le verin hydraulique (12) et le fluide se trouvant entre la soupape de retenue (15) et le piston de soupape simple (38), en reponse au mouvement dudit piston (38) en une seconde position.
