  • Patent number: 10704539
    Abstract: 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.

  • Publication number: 20160319812
    Abstract: 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.
