Hi, is anyone familiar with the name of this bike pump or style?

I think I've only had two or three bike pumps in my years riding. This has been one of the best ones I have owned. It doesn't have any branding on it, and all I remember is buying it from a certain Ike shop like idk maybe 4 years or more.

But it's been acting up really bad lately. When I pump, I could feel the inside springs or something jumping. And that's basically just releasing air out the side of the valve when I pump. It's lasted me a really long time, so it's one of the best purchases I ever made. Unfortunately, it's at the same time my tires are finished as well. Hopefully someone knows the name, so maybe I can find it online
