| description | A two-stage, variable force, solenoid control valve (10) for regulating fluid pressure can include a valve body (12) having a pilot fluid passage (14), including a metering land (16), in fluid communication with a flow amplifying fluid passage (18) through a valve control port (20) formed in the valve body (12). A solenoid operated pilot valve member (22), disposed in the pilot fluid passage (14), can have a metering orifice (24) operable in combination with the metering land (16) for selectively connecting the valve control port (20) with a pressurized fluid supply port (26) and a return exhaust port (28) in response to activation of a solenoid (34). A flow amplifying spool valve member (30), in fluid communication with the valve control port (20) of the pilot valve member (22) at one end (30a), can selectively connect a load control port (32) with the pressurized fluid supply port (26) and the return exhaust port (28) in response to pilot valve member (22) operation.
Une électrovanne à force variable à deux étages (10) permettant de réguler une pression de fluide peut comprendre un corps de vanne (12) comprenant un passage de fluide pilote (14) comprenant une région de dosage (16) en communication fluidique avec un passage de fluide d'amplification d'écoulement (18) à travers un orifice de commande de vanne (20) formé dans le corps de vanne (12). Un élément de vanne pilote commandé par solénoïde (22) disposé dans le passage de fluide pilote (14) peut comprendre un orifice de dosage (24) permettant, en combinaison avec la région de dosage (16), de raccorder sélectivement l'orifice de commande de vanne (20) à un orifice d'alimentation en fluide sous pression (26) et à un orifice d'échappement de retour (28) en réponse à l'activation d'un solénoïde (34). Un élément de vanne à tiroir d'amplification d'écoulement (30), en communication fluidique avec l'orifice de commande de vanne (20) de l'élément de vanne pilote (22) au niveau d'une extrémité (30a), permet de raccorder sélectivement un orifice de commande de charge (32) à l'orifice d'alimentation en fluide sous pression (26) et à l'orifice d'échappement de retour (28) en réponse à l'opération de l'élément de vanne pilote (22). |
