  • Collar assembly for pump thrust rod used to activate microswitch valve on chemical injection pump
    Patent number: 7481268
    Abstract: A collar assembly for inclusion with, or for a retrofit of, a chemical injection pump and method for manufacturing same. The collar assembly secures to a thrust rod of the chemical injection pump and may include a circular member having a central opening and a second opening offset from the central opening. The second opening receives a central portion of a continuous U-shaped member, wherein fingerlike extensions at opposite ends of the U-shaped member flank a toggle element of a switching mechanism. The fingerlike extensions actuate the toggle element so as to stroke the chemical injection pump. The collar assembly includes a reduced number of parts and a simplified manufacturing process.
