Abstract
An airless fluid dispensing apparatus, a stem-less spray valve, and a pressure relief valve are disclosed. The stem-less spray valve comprises a generally cylindrical valve body; a fluid conduit, operable to allow a flow of the fluid from a pump, at least partially through the valve body, to a spray orifice; a movable plug disposed at least partially within the valve body; a seat, shaped to conform to a shape of the movable plug; a spring disposed within the valve body. The spring biases the movable plug against the seat to prevent the fluid from flowing through the fluid conduit to the spray orifice when a fluid pressure is below a spray pressure threshold. When the fluid pressure reaches or exceeds the spray pressure threshold, the spring compresses, at least partially retracting the movable plug away from the seat, and allowing the fluid to flow through the fluid conduit to the spray orifice.
