Hollow valve plate

摘要

The hollow valve plate 1 of a piston compressor for liquid-cooled reed valves comprises a single half-shell 3 with cooling channels 4 which are open on the cylinder side, which said half-shell is covered by a reed plate 2 which is preferably welded or glued at least along the cooling channels 4 and has in the area of the suction openings 5 in each case one suction reed 6 which is machined out and is integrally connected on one side. Production and assembly are thereby simplified and the clearance is reduced.

1. A hollow plate valve for a piston compressor, said plate valve comprising:
a half shell which has opposite first and second surfaces and which defines a suction inlet opening therethrough and a cooling channel therein which opens to said first surface, a reed plate positioned adjacent and directly connected to said first surface of said half shell, said reed plate including a one-piece main body and an internal suction reed which is machined from and connected with said main body along only one side edge so as to be movable relative said main body for opening and closing said suction inlet opening of said half shell, and an endless bead between the reed plate and the half shell, said endless bead surrounding and sealing the cooling channel between the reed plate and the half shell.
