Claim:
A manifold assembly suitable to be mounted within an outer body of an automated sprayer, the automated sprayer being configured to deliver cleaning fluid from a reservoir to a spray nozzle, the manifold assembly comprising: a housing positionable within the outer body of the automated sprayer and having a cleaning fluid inlet passage, a cleaning fluid outlet passage, a cleaning fluid passageway therebetween, and a motor supported by the housing and being suitable to be operatively linked to a pump; and a pump mounted in the manifold assembly linked to both the cleaning fluid inlet passage and cleaning fluid outlet passage; wherein the housing also has a stand for supporting the motor; wherein the manifold assembly further comprises an air inlet, an air outlet, and an air passageway therebetween; wherein the manifold assembly further comprises a drainage passageway for carrying drainage fluid through the manifold assembly without passing through the cleaning fluid inlet passage or cleaning fluid outlet passage; wherein the housing comprises a first housing part and a second housing part that have been coupled together, with an elastomeric gasket sandwiched between the first housing part and the second housing part, the gasket being positioned so as to: (i) define a perimeter portion of the cleaning fluid passageway; (ii) define a perimeter portion of the air passageway; and (iii) define a perimeter portion of the drainage passageway; while also sealing the fluid passageway from the air passageway and also from the drainage passageway; wherein the elastomeric gasket is seated against the housing at a coupling between the first and second housing parts.
