Abstract
Abstract An automatic fluid control device designed to be combined with spray apparatus for controlling the flow of insecticide, fertilizer and the like is provided. The fluid control provides a valve responsive to a manual control and an automatic control governed by the speed of the vehicle carrying the spray apparatus. A pair of scanners correlates the vehicle speed with the spray flow by causing the valve plug to meter the flow as it rotates. The manual control displaces the valve plug along its longitudinal axis to provide a cumulative control of the fluid flow.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
227 words
A device for controlling the flow of fluid comprising a fluid conduit adapted to be connected to a source of fluid, a valve body mounted in said fluid conduit, said valve body including a cylindrical bore and passageways in communication with the fluid conduit, a valve regulator means mounted in the valve body for controlling the flow of fluid, said valve regulator means including a cylindrical plug mounted in the cylindrical bore and positioned perpendicularly to the fluid flow, the plug having a passageway capable of being aligned with the passageway in the valve body, a first adjusting means for moving the valve regulator in one direction to vary the flow, said first adjusting means including a manually adjustable control member, means for producing a signal indicating the desired fluid flow, and a second adjusting means for moving the valve regulator in a second direction to vary the flow, said second adjusting means including a control means for positioning the valve regulator means in response to the variable signal, both adjusting means providing cumulative control of the total flow of fluid, whereby the plug of said valve regulator means is movable in a direction perpendicular to the fluid flow by the manually adjustable control member and rotatable around its axis by the control means in response to the variable signal to provide control of the fluid flow.
Claim 2
Independent Claim
227 words
A device for controlling the flow of fluid comprising a fluid conduit adapted to be connected to a source of fluid, a valve body mounted in said fluid conduit, said valve body including a cylindrical bore and passageways in communication with the fluid conduit, a valve regulator means mounted in the valve body for controlling the flow of fluid, said valve regulator means including a cylindrical plug mounted in the cylindrical bore and positioned perpendicularly to the fluid flow, the plug having a passageway capable of being aligned with the passageway in the valve body, a first adjusting means for moving the valve regulator in one direction to vary the flow, said first adjusting means including a manually adjustable control member, means for producing a signal indicating the desired fluid flow, and a second adjusting means for moving the valve regulator in a second direction to vary the flow, said second adjusting means including a control means for positioning the valve regulator means in response to the variable signal, both adjusting means providing cumulative control of the total flow of fluid, whereby the plug of said valve regulator means is movable in a direction perpendicular to the fluid flow by the manually adjustable control member and rotatable around its axis by the control means in response to the variable signal to provide control of the fluid flow.
Claim 3
Dependent Claim
166 words
In combination a liquid spraying apparatus for dispensing chemical insecticides, fungicides, fertilizers and the like mounted on a vehicle and a device for controlling the flow of fluid comprising a fluid conduit, a source of liquid connected to the fluid conduit, a valve body mounted in the fluid conduit, a valve regulator means mounted in the valve body, a first adjusting means for moving the valve regulator in one direction to vary the flow of fluid, a second adjusting means for moving the valve regulator in a second direction to vary the flow, and means for indicating the speed of the vehicle on which the spray apparatus is mounted, said means for indicating the speed of the vehicle including a revolution counter pointer and a pair of scanner means, wherein the scanner means are responsive to the revolution counter pointer and generate a signal for positioning the valve regulator means, whereby the second adjusting means is actuated by the speed signal to regulate the fluid flow.
Claim 4
Dependent Claim
166 words
In combination a liquid spraying apparatus for dispensing chemical insecticides, fungicides, fertilizers and the like mounted on a vehicle and a device for controlling the flow of fluid comprising a fluid conduit, a source of liquid connected to the fluid conduit, a valve body mounted in the fluid conduit, a valve regulator means mounted in the valve body, a first adjusting means for moving the valve regulator in one direction to vary the flow of fluid, a second adjusting means for moving the valve regulator in a second direction to vary the flow, and means for indicating the speed of the vehicle on which the spray apparatus is mounted, said means for indicating the speed of the vehicle including a revolution counter pointer and a pair of scanner means, wherein the scanner means are responsive to the revolution counter pointer and generate a signal for positioning the valve regulator means, whereby the second adjusting means is actuated by the speed signal to regulate the fluid flow.
Claim 5
Dependent Claim
25 words
The combination of claim 2 wherein the pair of scanner means are connected to the valve regulator means and rotate with the valve regulator means.
Claim 6
Dependent Claim
100 words
The combination of claim 2 wherein the valve body includes a cylindrical bore and passageways in fluid communication with the fluid conduit and the valve regulator means includes a cylindrical plug mounted in the cylindrical bore having a fluid passageway capable of being aligned with the valve body passageways to meter the fluid flow, the plug is mounted with its longitudinal axis perpendicular to the fluid flow, whereby the first adjusting means moves the cylindrical plug in the direction of the longitudinal axis and the second adjusting means rotates the cylindrical plug to provide cumulative metering of the fluid flow.
Claim 7
Dependent Claim
40 words
The combination of claim 4 wherein the passageway of the cylindrical plug is dimensioned in relation to the passageways of the valve body to provide a metering of fluid flow that is substantially linear to the speed of the vehicle.
Claim 8
Dependent Claim
14 words
The combination of claim 4 wherein the passageway of the cylindrical plug is elliptical.
Claim 9
Dependent Claim
57 words
The combination of claim 5 wherein the first adjusting means includes a screw threaded member for positioning the cylindrical plug; a spring means for biasing the cylindrical plug and the second adjusting means includes a counter means for determining the vehicle speed, gear means for rotating the cylindrical plug, and a motor for actuating the gear means.
