Abstract
A blade valve for a compressor comprises two discs which are arranged one above the other with the interposition of a seal. The discs are provided with ducts for the controlled medium and form both the valve seat and the catcher. In the seal, whose thickness determines the valve stroke, elongate recesses are provided for the blades which control the passage ducts. At the ends of the recesses, stepped stops are provided in the seal for the ends of the strip-like blades which are loosely inserted into the recesses. The stepped stops may be formed by profiled strips which are inserted at the ends of the recesses and which extend transversely to the longitudinal direction of the blades.
