Disc valve for piston compressors

摘要

The invention relates to a disc valve for piston compressors with at least one flexible disc, which screws on the root against a seating or catcher plate and is secured in the correct position in relation to the associated seating aperture by at least two axially parallel dowel pins, which are anchored in the seating or catcher plate and passed through fitting holes of the disc. For adherence to the tolerances in efficient mass production it is proposed that the pins (9) be stamped out of the seating plate (1) or the catcher plate (4) and domed, as can best be seen from Fig.3. <IMAGE>
