Ordering by number: this is H3439427, which also shows up as 3310190079, the Chicago Pneumatic spring. Springs in a hammer fatigue with cycle count rather than age, so a control that has gone lazy or fails to return is usually this part rather than the component it drives.
It shows up in the parts breakdown for the CP 0122SVR 0125SVR Pick Hammer and FL0022VR FL0022SVR Clay Digger, and on 1 other machine. Worth matching the reference number on the diagram against your own machine before you order the same part number can sit in more than one position.
The parts diagram hub indexes every breakdown we publish, and the Chicago Pneumatic lineup has the tools these parts go into. Stocked in Denver orders placed by 4 PM ET ship the same day when the part is on the shelf.
