ABSTRACT:
A valve for a piston-type compressor includes a valve seating with throughflow channels, a closure piece for controlling these channels, a spacer and a spring means urging the closure piece against the valve seating and supported on an arrester which at the same time forms the limit stop for the closure piece. In order to anchor the valve parts on the valve seating before the installation of the valve, at least one sleeve serving as a transport securing means and as an assembly aid is provided, which is secured at one end on the valve seating or on the arrester, and the individual valve parts are pushed in the correct installation position onto the sleeve. The other end of the sleeve is widened. A tension screw passes through the sleeve in an axial direction. The sleeve can be rolled into an undercut annular groove of the valve seating and at the outer surface of the arrester end flush with the latter.
