Description

CROSS-REFERENCE TO RELATED APPLICATION The present application is a continuation of and claims priority of U.S. patent Ser. No. 18/306,577, filed Apr. 25, 2023, which is a continuation of and claims priority of U.S. patent application Ser. No. 17/182,717, filed Feb. 23, 2021, which is based on and claims the benefit of U.S. provisional patent application Ser. No. 63/000,516, filed on Mar. 27, 2020, the contents of which are hereby incorporated by reference in their entirety. BACKGROUND A fluid spraying system may be used by an operator to deliver a fluid from a fluid source to an application area. For example, paint may be sprayed, or otherwise applied, by an applicator, such as a spray gun, to an application area, such as a surface of a wall. In order to deliver the different fluids from the fluid source to the application area, a conveyance system, such as a pump, can be used to convey the fluid from the fluid source, under pressure, through a fluid passageway and out of an outlet of the applicator to be applied to the application area. The pressure generated by the conveyance system can require the fluid spraying system to have certain structural features and material integrity (e.g., pressure ratings) to allow safe and efficient operation of the fluid spraying system. The discussion above is merely provided for general background information and is not intended to be used as an aid in determining the scope of the claimed subject matter. The claimed subject matter is not limited to implementations that solve any or all disadvantages noted in the background. SUMMARY A fluid applicator configured to receive a pressurized fluid includes a pressure vessel configured to receive the pressurized fluid from a fluid delivery line. The pressure vessel includes a valve chamber configured to receive a valve assembly, a filter chamber configured to receive a filter assembly, and a fluid delivery line fitting configured to be coupled to the fluid delivery line. The fluid applicator further including a tip assembly coupled to the pressure vessel and configured to atomize the pressurized fluid.

It should be understood that numerous other modifications and examples can be devised by those skilled in the art which fall within the scope and spirit of the principles of this disclosure. DETAILED DESCRIPTION Spraying systems, such as airless spraying systems, work by pumping fluid at pressure through a fluid delivery line and out of an outlet in a spray tip. The pump (or other conveyance mechanism) can, in some instances, pressurize the fluid at very high pressures, for example, 1500-3500 pounds per square inch (PSI). In some cases, safety and/or industry standards may require that the spraying system have a pressure rating up to or at least three times the operating pressure. For the spraying system to withstand these operating pressures such that the fluid pathway maintains a seal, relatively robust materials (e.g., metal) and/or additional parts can be required. Fo
