ABSTRACT:
A delivery valve, especially for a rotary piston compressor, which valve is adapted to be inserted into an opening provided in the compressor housing and extending substantially parallel to the axis of the compressor housing. The compressor housing has a bore in which is fitted a sleeve which has tangentially directed valve slots and forms a valve seat. The sleeve surrounds a member which over its entire length has an approximately horseshoe shape. That portion of the horseshoe shaped part which is located opposite the open side thereof faces toward the valve slots and has a greater bending radius than the sleeve. The free ends of the horseshoe shaped part which define the open side of the horseshoe shaped part are bent back toward the outside of this part while the lateral flanks of the horseshoe part bear against the sleeve. The flanks of the horseshoe shaped part have tangentially directed lateral perforations in which are guided parallel strip-shaped cutouts or tongues of a resilient sheet metal the marginal portions of which are clamped into the bent back portions of the horseshoe shaped part, the arrangement being such that the cutouts bear against the sleeve in front of the valve slots when the valve is closed.
