Abstract
An airless paint or material spray system having a pressure sensor and regulator for controlling the pressure of paint flowing from a paint pump to an airless spray gun. The pressure sensor and regulator includes three contiguous flexing diaphragms in a material chamber in the outlet flow line of the pump with the outermost diaphragm in direct contact with material being constructed of a thin plastic impervious to attack by common painting or coating materials. The two other diaphragms are rubber coated fabric diaphragms that axially position a precision steel rod movably mounted in a low clearance bore in a regulator housing. The axial movement of the precision rod is converted to rotational movement by an adjustably spring biased, pivotally mounted member in the housing having a universal connection with the precision rod. A normally closed snap action switch in the housing is actuated after a predetermined axial travel of the precision rod by an amplifier bar connected to the pivotally mounted member. This snap action switch is adapted to energize a dumping valve in the outlet of the pump at approximately 60 cycles per minute to maintain a desired pump outlet pressure.
