Abstract: A nozzle assembly includes a nozzle housing (86) defining an inner chamber (91) and a mixer (90) disposed within the inner chamber. The nozzle housing includes a nozzle housing and a nozzle orifice. The nozzle receive is configured to connect to a sprayer housing and to receive a first material, a second material, and air. The nozzle orifice is configured to spray a plural component material formed by a mixture of the first material and the second material. The mixer includes a shaft (92), an extension (94), an air channel, and inlet orifice formed in a first end of the shaft, and an outlet orifice formed between the air channel and a surface of the shaft. The extension defines a mixing channel extending between the shaft and the inner surface of the housing and the air channel is defined by an inner surface of the shaft and extends partially axially through the shaft.

Abstract: A pump system includes a housing, a lubricant system, and control circuitry. The housing includes a pump chamber defined by the housing and a throat seal. The lubricant system includes a lubricant pump, a lubricant gallery defined within the housing of the main pump, and a lubricant circuit fluidly connecting the lubricant pump and the lubricant gallery. The throat seal is disposed adjacent to and between the pump chamber and the lubricant gallery. The control circuitry is configured to cause the lubricant pump to pump a purge volume of lubricant through the lubricant system, cause the lubricant pump to stop pumping for a first time period after the lubricant pump has pumped the purge volume, and cause the lubricant pump to pump the purge volume of lubricant through the lubricant system after the first time period.

Abstract: A pour spout adapter comprises a housing, a collar and a threaded engagement. The housing has a sealed bore for receiving a tube. The collar has an internal bore coupled to the housing at a rotatable connection so as to permit a tube to extend from the sealed bore through the collar. The threaded engagement is disposed on the internal bore to receive a threaded pour spout.
