Classification: CPC F  B | IPC B  F

Claim 0:
1. A hand portable apparatus comprising:
a pump having an inlet side and an outlet side, wherein the inlet side is configured to fluidly couple to a fluid supply;
a pressure sensor operably coupled to the outlet side and configured to measure a fluid pressure at the outlet side;
a pressure-actuated controller coupled to the pressure sensor, wherein the pressure-actuated controller is configured to:
turn on the pump in response to the fluid pressure at the outlet side below a first preselected pressure set point and turn off the pump in response to the fluid pressure at the outlet side above a second preselected pressure set point;
cycle between the first and second preselected set points unless a fluid flow rate at the outlet side exceeds a first value wherein the fluid pressure at the outlet side then remains below the first preselected fluid pressure set point and wherein the first preselected pressure set point is less than the second preselected pressure set point;

a sponge wherein the sponge comprises perforations; and
a low-flow device coupled to the outlet side and wherein the low-flow device comprises a perforated tube with perforations about the perforated tube onto which the perforations of the sponge are coupled and wherein the sponge is configured to dispense fluid through the perforations of the sponge;
wherein the low-flow device is fluidly coupled to the sponge, the sponge is fluidly coupled to a flow valve, and the flow valve is fluidly coupled to the outlet side, wherein:
the low-flow device is configured to dispense fluid from one or more openings in the low-flow device;
the flow valve is configured to deliver a flow-rate of the fluid adjustable to any value within a preselected range from about 0.01 gallons per minute (gpm) to about 2.5 gpm when the fluid pressure at the outlet side of the pump assembly decreases to the first preselected pressure set point and remains below the second preselected pressure set point; and
wherein the first value is less than about 2.5 gpm.
