Definitions
- the invention relates to an electric refrigerant compressor, in particular for household refrigerators and freezers, with an outer housing, an inner body contained in the named outer housing, a pressure chamber integrated in such an inner body, and a lid with which the opening of this pressure chamber can be closed is, the lid and the pressure chamber by means are provided with which the lid in its closed position can be held and in particular a special design the closure of the pressure chamber one especially for the Use in conjunction with household refrigerators and / or freezers provided hermetic refrigeration compressor.
- the second disadvantage has more to do with functionality, since the presence of said shoulder D and the screw within the pressure chamber to a significant reduction of the volume of the pressure chamber and thus to a reduction the sound-absorbing effectiveness.
- FIG. 1 shows a schematic sectional view of the Pressure chamber of a refrigerant compressor according to the current one State of the art
- Figure 2 is a schematic sectional view of the Pressure chamber of a refrigerant compressor according to this invention
- 3 shows an enlarged view of a detail from FIG.
- the opening 12 of the pressure chamber in turn has a corresponding one annular flat outer edge, the mutual Dimensions and shapes are selected so that the Lid can be placed on the opening so that the ring-shaped Flat outer edges cannot be removed due to material changes get connected.
- this solution also allows the Avoid using a gasket because of the nature of this connection between the lid and the opening of the pressure chamber tight closure even at the high pressures in the Pressure chamber can prevail, secures.
- the lower Contact angle a must be between 70 ° and 90 °.
- Rib for the purpose of a optimized merging of the mentioned edges such Rib must have a height h between 0.2 and 1.2 mm.
