A rotational speed governor for an air motor comprises a housing, a valve, a shaft, a cross-bar, a plate and a pair of weights. The housing has an air inlet and an air outlet. The valve is disposed between the air inlet and the air outlet. The shaft extends along an axis within the housing. The cross-bar is connected to the shaft. The plate intersects the shaft between the valve and the crossbar. The weights are rotatably connected to the crossbar at pivot points. Each weight comprises an arcuately profiled edge extending beyond the crossbar to engage the plate. The arcuately profiled edges are shaped to increase a moment arm on the plate as the weights pivot away from the shaft.

A control method for a two-component spray system having first and second pumps for separate fluid components includes registering a target spray pressure, registering a material-specific pressure factor margin, sensing an output pressure of the second pump, and identifying a failure condition in the event that the sensed output pressure remains further than the pressure factor margin from the target spray pressure for at least a threshold time.

A metering pump includes a motor having a motor shaft extending through a drive housing, a carriage assembly disposed around the motor shaft and within the drive housing, a plunger return block mounted to the carriage assembly, a piston disposed along an axis, and a carriage bearing disposed on the motor shaft and within the carriage assembly, slidably coupled to the carriage assembly, and configured to provide a second contact point for maintaining the alignment of the carriage assembly with the axis of the piston. The piston further includes a stroke adjuster mounted to the carriage assembly to provide a first contact point for maintaining the alignment of the carriage assembly with the piston, a drive shaft connected to the stroke adjuster, and a plunger connected to the drive shaft. The metering pump also includes a cam coupled to the motor shaft to rotate with the motor shaft and a bearing disposed around the cam to rotate therewith and to contact the stroke adjuster and the plunger return block.

A pneumatic timing valve includes a spool and seal system having a first seal cartridge and a spool. The first seal cartridge has an annular body with radial ports. The spool is positioned within the first seal cartridge and movable between a first and second position. The spool has a central bore and radial ports that intersect the central bore. The radial ports of the spool complement the radial ports of the seal cartridge. The seal cartridge radial ports, the spool radial ports, and the central bore of the spool define fluid flow passages.

A control method for a two-component spray system having first and second pumps for separate fluid components includes registering a target spray pressure, registering a target primary-to-secondary spray component flow ratio, sensing an output pressure of the first pump, controlling the first pump to a first speed set via a proportional-integral-derivative loop using the sensed output pressure and the target spray pressure, and controlling the second pump to a second speed equal to the first speed multiplied by the target primary-to-secondary spray component flow ratio.

A method of actuating a double-action pump assembly with a reciprocating plunger includes signaling the reciprocating plunger to stop for a changeover period; while the pump is stopping, signaling the first inlet and outlet valves to close; while the first inlet and outlet valves are closing, signaling the second inlet and outlet valves to open, such that the second inlet and outlet valves begin to mechanically open at least a dwell period after the first inlet and outlet valves have entirely closed; and signaling the reciprocating plunger to begin moving while the second inlet and outlet valves are closing.
