1. A portable spray apparatus for use in dispensing a fluid, comprising:
- a body portion provided on a chassis, the chassis comprising a plurality of wheels adapted for conveying the apparatus;
a clean fluid storage tank positioned at least partially within the body portion and having an internal volume to receive a fluid;
a pump provided at least partially within the body portion, the pump comprising a fluid inlet in fluid communication with the clean fluid storage tank and a pump outlet in fluid communication with an accumulator;
wherein the accumulator comprises an internal pressure supplied by the pump, and wherein the accumulator is associated with a device which maintains the internal pressure of the accumulator between approximately 50 PSI and 150 PSI;
wherein the pump withdraws fluid from the clean fluid storage tank upon activation;
a supply hose extending from the body portion and having a first end in fluid communication with the accumulator to receive the fluid;
a spray gun connected to a second end of the supply hose; and
a spray nozzle mounted to the spray gun, wherein the spray nozzle is sized to create a spray of fluid upon activation of the spray gun.

Abstract
A portable spray apparatus is provided. The apparatus is a self-contained portable unit having storage and dispensing capabilities for a fluid, including a disinfecting fluid. A pump and a pressure accumulator are provided in series and further connected to a spray gun or wand for dispensing a fluid. A detachable coupling allows a user to separate the pressure accumulator from the pump such that a user may spray disinfecting fluid in hard-to-reach areas.

10. A portable spray apparatus, comprising:
-
a clean fluid storage tank having an internal volume to receive a fluid; a pump comprising a fluid inlet in fluid communication with the clean fluid storage tank, and a pump outlet in fluid communication with an accumulator, wherein the accumulator has an internal pressure supplied by the pump, wherein the pump withdraws the fluid from the clean fluid storage tank upon activation; a detachable coupling disposed between the pump outlet and the accumulator, the detachable coupling having an attached state and a detached state, wherein in the attached state the coupling allows fluid communication between the pump outlet and the accumulator, and in the detached state the coupling prevents fluid communication between the pump outlet and the accumulator; a supply hose having a first end in fluid communication with the accumulator to receive the fluid; a spray gun connected to a second end of the supply hose; a spray nozzle mounted to the spray gun, wherein the spray nozzle is sized to create a spray of fluid upon activation of the spray gun; and wherein the accumulator, supply hose, spray gun, and spray nozzle are separable from the pump when the coupling is in the detached state. - View Dependent Claims (11, 12, 13, 14, 17, 18, 19)

20. A portable spray apparatus for use in dispensing a fluid, comprising:
-
a body portion provided on a chassis, the chassis comprising a plurality of wheels adapted for conveying the apparatus; a clean fluid storage tank positioned at least partially within the body portion and having an internal volume to receive a fluid; a pump provided within the body portion, the pump comprising a fluid inlet in fluid communication with the clean fluid storage tank and a pump outlet in fluid communication with an accumulator; wherein an internal pressure of the accumulator is supplied by the pump, and wherein the accumulator is associated with a device which maintains the internal pressure of the accumulator between approximately 85 PSI and 110 PSI; wherein the pump withdraws a fluid from the clean fluid storage tank upon activation, wherein the activation is the internal pressure of the accumulator between approximately 85 PSI; a rechargeable battery provided within the body portion, wherein the rechargeable battery supplies power to the pump, wherein the rechargeable battery has a voltage rating, and the pump has a voltage rating, and wherein the battery voltage rating is approximately 33% of the pump voltage rating; a detachable coupling disposed between the pump outlet and the accumulator, the detachable coupling having an attached state and a detached state, wherein in the attached state the coupling allows fluid communication between the pump outlet and the accumulator, and in the detached state the coupling prevents fluid communication between the pump outlet and the accumulator; a supply hose extending from the body portion and having a first end in fluid communication with the accumulator to receive the fluid; a spray gun connected to a second end of the supply hose; a spray nozzle mounted to the spray gun, wherein the spray nozzle is sized to create a spray of fluid upon activation of the spray gun; and wherein the accumulator, supply hose, spray gun, and spray nozzle are separable from the pump when the coupling is in the detached state.
