Abstract
A motion-powered liquid sprayer that can increase the number of rotations of the pump relative to each rotation of the wheel or axle is provided. The sprayer can include a gearing assembly that employs gears to increase the number of pump revolutions as a function of the wheel or axle rotation. The sprayer can also include a gear pump that employs an over-capacity or enhanced gullet together with blow-by spacing to control consistent liquid flow relative to variable motional velocities.
Claims20
A motion-activated sprayer apparatus, comprising:
- a vessel that holds a volume of liquid;
- at least two passageways in fluid communication with the vessel;
- a pump in fluid communication with one of the at least two passageways of the vessel, wherein the pump is driven as a function of rotation of at least one wheel of the motion-activated sprayer apparatus;
- and
- a switching means in communication with the pump, wherein the switching means directs fluid from the vessel to either a distribution mechanism or back into the vessel via the other of the at least two passageways based at least in part upon an operator selection of a bypass or spray mode.
A fluid pump, comprising:
- a first housing portion;
- a second housing portion that fixedly mates to the first housing portion to create a cavity therein, wherein the second housing portion includes at least one inlet and at least one outlet passageway;
- a first spur gear disposed within the cavity;
- and
- a second spur gear disposed within the cavity, wherein the second spur gear connectively engages with the first spur gear to form an over-sized gullet, and wherein the over-sized gullet is partially filled or emptied via blow-by enabled by a cavity depth in excess to a depth of each of the first or second spur gear, and wherein the connective engagement transmits fluid from the inlet to the at least one outlet passageway.
A sprayer apparatus, comprising:
- means for retaining fluid;
- means for pressurizing a volume of the fluid;
- at least one of:
- means for selectively directing the volume of the fluid to a spray means;
- or
- means for selectively re-directing the volume of the fluid into the retained fluid, wherein the redirection agitates the retained fluid.
