1. A compressor valve assembly comprising:
- a reed (100) having a base portion (104) and a tip (102); and
a compressor valve plate (80) comprising;
a mounting surface portion for mounting the base portion (104) of the reed (100);
a port (90);
a seat (150) surrounding the port;
a trepan (154) being an annular relief area fully surrounding the seat; and
a flat distal relief area (180) and a flat proximal relief area (182) each having a depth relative to the mounting surface portion less deep than the trepan, the proximal relief area extending proximally of the trepan and the distal relief area extending distally of the trepan with the proximal relief area (182) being between the seat and the mounting surface portion, said base portion (104) being mounted to the mounting surface portion, said tip (142) extending over the distal relief area, the distal relief area extending distally beyond an end of the tip.

Abstract
A compressor valve plate (80) for a reed valve (94) has a mounting surface portion for mounting a base portion (104) of a reed (100). The compressor has a port (90). A seat (150) surrounds the port. A trepan (154) surrounds the seat. A relieved area (180, 182) less deep than the trepan extends proximally (182) of and distally (180) of the trepan. A reciprocating piston compressor comprises a valve assembly having such a compressor valve plate and a reed.
