초록 ▼

A two-stage solenoid valve uses a pair of stacked coaxial armatures separated by a predetermined gap which is maintained by a first spring therebetween. A coaxial connecting rod extends between a first armature and the second armature and is attached to the first armature. A head on the unattached end of the rod bears against a bottom surface of a recess in the second armature to limit the expansion of the first spring. A second spring is arranged to contact the head of the rod and to extend therefrom to a fixed plug in the end of a cylindrical housing surrounding the first and second armatures. The first armature is provided with a fluid sealing surface on a first end for sealing an adjacent fluid port in the valve in response to the spring force exerted by the second spring. A first and a second solenoid coil assembly are coaxially stacked to surround the cylindrical sleeve housing adjacent to respective ones of the first and second armatures. The coils are connected in series with a center tap connection therebetween to allow either parallel or single coil energization. Selective energization of the first and second electromagnetic solenoid coil assemblies is used to control the positioning of the first and second armatures to provide a first and a second spacing of the sealing surface from the orifice during an open state of the valve to provide a first and a second flow rate, respectively, through the valve.

1. A two-stage solenoid valve comprising orifice means for providing a fluid path, sealing means for sealing said orifice means, armature means for urging said sealing means toward said orifice means, said armature means including a first and a second armature, a fixed stop means and a first resilient means for establishing a gap between said stop means and said first and said second armatures, said first and second armatures being coaxial and solenoid drive means for selectively establishing in response to first and second energizing signals corresponding first and second positions of said armature mean to provide a first and a second spacing, respectively, of said sealing means with respect to said orifice means to effect a corresponding first and a second flow rate through the valve, said drive means including first actuating means for eliminating said gap to establish said first position of said sealing means in response to said first energizing signal, wherein said armature means includes a connecting rod extending between said first and second armatures, means attaching one end of said rod to said second armature and means allowing said first armature to slide on said rod, said rod having a head on a second end thereof bearing against a first end of said first resilient means with a second end of said first resilient means contacting said fixed stop means, wherein said armature means includes a second resilient means for establishing a gap between said first and said second armatures and said drive means includes second actuating means for eliminating said gap between said armatures in response to said second energizing signals to establish in combination with said first actuating means said second position of said sealing means. 2. A valve as set forth in claim 1 wherein said rod is coaxial with said first and second armatures. 3. A valve as set forth in claim 1 wherein said first and second resilient means include respective coil springs. 4. A valve as set forth in claim 1 wherein said sealing means includes a fluid sealing ring attached to said armature means. 5. A valve as set forth in claim 1 wherein said first actuating means includes a first solenoid coil assembly and second actuating means includes a second solenoid coil assembly, said first armature being responsive to an energization of said first solenoid assembly and second armature being responsive to an energization of said second solenoid coil assembly. 6. A valve as set forth in claim 1 wherein said sealing means includes a resilient surface located on an outside surface of said second armature facing said orifice means. 7. A valve as set forth in claim 4 wherein said first resilient means is arranged to urge said resilient surface against said orifice means during a non-energized state of said drive means. 8. A valve as set forth in claim 1 wherein said armature means includes a housing means for maintaining the coaxial relationship of said first and second armatures and for coaxially aligning said first and second solenoid coils.
