Abstract
A combined compressor pressure sensor and excess pressure relief valve (12) uses a formed disk (22) that snaps down and back up at a pair of predetermined pressures. The disk (22), when it snaps down, opens a plug (34) to in turn allow excess pressure from the compressor (10) to escape. When up, the plug (34) remains sealed, the outside vents (42) remain blocked, and compressor gas flow only through the center of the plug (34) and disk (22) to a sensing chamber (46).
