Claims

[Scope of utility model registration request]

A cover facing the discharge port of the cylinder is attached to the outer wall of the cylinder, and a discharge valve for opening and closing the discharge port, which is formed by bending an elastic thin plate into an annular shape, is provided on the cylinder side recess provided in the cylinder and on the cover side provided in the cover. The discharge valve is held by a holder that presses both ends of the discharge valve against the cover side recess, and prevents excessive deformation of the discharge valve. In the compressor discharge valve mounting structure, a valve stopper is provided upright in the cover-side recess, and the valve stopper and the discharge port face each other across the middle part of the discharge valve. A valve stopper relief hole for allowing the valve stopper to escape is provided in the part, the holder is fitted into the valve stopper, and a plurality of holder fixing protrusions are provided in the middle of the holder around the valve stopper relief hole. A plurality of cover-side holder stoppers are provided at predetermined intervals along the holder, and a plurality of cover-side holder stoppers corresponding to each of the holder fixing protrusions are provided in the cover-side recess, and a plurality of cylinder-side holder stoppers corresponding to each of the cover-side holder stoppers are provided. A discharge valve mounting structure for a compressor, which is provided in the cylinder side recess, and wherein the cover side holder stopper and the cylinder side holder stopper sandwich the holder fixing protrusion.
