Abstract
Abstract A solenoid flow control valve including an intake fluid conduit having an inlet and an outlet; a valve stopper mounted to the intake fluid conduit; a solenoid coil mounted about the intake fluid conduit; a hollow solenoid plunger slidably mounted between the solenoid coil and the intake fluid conduit so that fluid flow will forcibly slide the plunger downstream and energization of the coil will electromagnetically force the plunger to slide upstream; and the plunger having valve seat means for increasing fluid flow through the conduit when the coil is deenergized and decreasing fluid flow when the coil is energized. The control valve may include a frame assembly having a top opening and an exhaust fluid inlet located therebelow; the intake fluid conduit having a flange which slidably mounts the conduit in the frame assembly and the flange having an exhaust fluid passageway above the exhaust fluid inlet; the top end of the intake fluid conduit having a cap for sealably plugging the top opening of the frame assembly when the intake fluid conduit is slid to a downstream position; and means for biasing the intake fluid conduit to the upstream position.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
100 words
A solenoid flow control valve comprising: an intake fluid conduit having an inlet and an outlet: a valve stopper mounted to the intake fluid conduit; a solenoid coil mounted about the intake fluid conduit; a hollow solenoid plunger slidably mounted between the solenoid coil and the intake fluid conduit so that fluid flow will forcibly slide the plunger downstream and energization of the coil will electromagnetically force the plunger to slide upstream; and the plunger having valve seat means for increasing fluid flow through the conduit when the coil is deenergized and decreasing fluid flow when the coil is energized.
Claim 2
Dependent Claim
100 words
A solenoid flow control valve comprising: an intake fluid conduit having an inlet and an outlet: a valve stopper mounted to the intake fluid conduit; a solenoid coil mounted about the intake fluid conduit; a hollow solenoid plunger slidably mounted between the solenoid coil and the intake fluid conduit so that fluid flow will forcibly slide the plunger downstream and energization of the coil will electromagnetically force the plunger to slide upstream; and the plunger having valve seat means for increasing fluid flow through the conduit when the coil is deenergized and decreasing fluid flow when the coil is energized.
Claim 3
Dependent Claim
102 words
A solenoid flow control valve as claimed in claim 1 including: means mounting the valve stopper to the intake fluid conduit at a location downstream from said vAlve stopper; the valve seat means being located at the extreme downstream end of the plunger and forming a nozzle for discharging the fluid from the intake fluid conduit; and said valve seat means being located on a downstream side of the valve stopper so that fluid flow is increased when the valve seat means travels in a downstream direction and fluid flow is decreased when the valve seat means travels in an upstream direction.
Claim 4
Dependent Claim
204 words
A solenoid flow control valve comprising: an intake fluid conduit having an inlet and an outlet; a valve stopper; means mounting the valve stopper to the intake fluid conduit at a location downstream therefrom; a solenoid coil mounted about the intake fluid conduit; a hollow solenoid plunger slidably mounted between the solenoid coil and the intake fluid conduit so that fluid flow will forcibly slide the plunger downstream and energization of the coil will electromagnetically force the plunger to slide upstream; the plunger having valve seat means for increasing fluid flow through the conduit when the coil is deenergized and decreasing fluid flow when the coil is energized; the valve seat means being located at the downstream end of the plunger and forming a nozzle for discharging the fluid from the intake fluid conduit; a sleeve mounted about the solenoid coil having an upstream inwardly projecting flange which is fixedly connected to the intake fluid conduit and forms an upstream stop for the plunger; said sleeve having at its downstream end inwardly projecting means for slidably engaging the plunger; and said inwardly projecting means and said plunger each having a shoulder which are engageable with one another to stop downstream movement of the plunger.
Claim 5
Dependent Claim
204 words
A solenoid flow control valve comprising: an intake fluid conduit having an inlet and an outlet; a valve stopper; means mounting the valve stopper to the intake fluid conduit at a location downstream therefrom; a solenoid coil mounted about the intake fluid conduit; a hollow solenoid plunger slidably mounted between the solenoid coil and the intake fluid conduit so that fluid flow will forcibly slide the plunger downstream and energization of the coil will electromagnetically force the plunger to slide upstream; the plunger having valve seat means for increasing fluid flow through the conduit when the coil is deenergized and decreasing fluid flow when the coil is energized; the valve seat means being located at the downstream end of the plunger and forming a nozzle for discharging the fluid from the intake fluid conduit; a sleeve mounted about the solenoid coil having an upstream inwardly projecting flange which is fixedly connected to the intake fluid conduit and forms an upstream stop for the plunger; said sleeve having at its downstream end inwardly projecting means for slidably engaging the plunger; and said inwardly projecting means and said plunger each having a shoulder which are engageable with one another to stop downstream movement of the plunger.
