Abstract
A pressure relief valve is provided that includes a valve housing, a poppet valve and a damper. The valve housing includes a valve seat and a bore. The poppet valve includes a head and a stem. The head is configured to engage the valve seat when the poppet valve is in a closed position. The head is configured to disengage the valve seat when the poppet valve is in an open position. The stem projects axially out from the head and through the bore. The damper includes a damper chamber axially between the valve housing and the head.

A pressure relief valve, comprising:
- a valve housing including a valve seat and a bore;
- a poppet valve including a head and a stem, the head engaging the valve seat when the poppet valve is in a closed position, the head disengaged from the valve seat when the poppet valve is in an open position, and the stem projecting axially out from the head and through the bore;
- and
- a damper comprising a damper chamber axially between the valve housing and the head;
- wherein the poppet valve further includes a sleeve spaced radially outward from the stem, and the sleeve projects axially out from the head;
- and
- wherein the valve housing further includes a valve mount disposed radially between the sleeve and the stem, and the bore projects axially through the valve mount.
