Individual co-current circuit valve for piston compressors

摘要

The invention relates to an individual co-current circuit valve for piston compressors with an annular set of valve seats and plates arranged in said circuit valve. Known valves of this kind have the disadvantage that a special device is required for clamping the valve seat and the set of plates and that the aerodynamic conditions are unfavourable. The underlying object of the invention is to eliminate the disadvantages of the known designs and to provide an individual co-current circuit valve with improved aerodynamic properties and a more favourable construction. The object is achieved by the fact that the valve is designed with an inner annular groove on the outer flange of an insertion opening, in which groove there rests a split spring ring, and tightening bolts are provided on the flange, the connecting ribs of the cover lying in a conical plane and a spring sleeve and a centring disc being arranged concentrically in the annular set. A bolt is mounted on the disc so as to project freely. The spring sleeve forms a thin-walled cylinder which has an oblique cut. The centring disc is designed as a circular plate with a central stepped hole, its outer surface including a stud and an outer ring. <IMAGE>
