Problems solved by technology

However, this parting surface leads to other disadvantages
Thus, for example, the production of inclined parting surfaces is associated with greater effort from the point of view of production technology than the production of horizontal parting lines, since other production machines have to be used or existing ones have to be retrofitted and / or reprogram
Furthermore, the arrangement of the components of the refrigerant compressor, in particular the arrangement of the piston pump, is also problematic
Although the connecting piece can be integrated into the cover of the housing compressor by means of an inclined parting line, there is however a risk of the connecting piece colliding with the electric piston pump

Embodiment Construction

[0033] Reference below figure 1 and figure 2 . The present invention provides a hermetically enclosed refrigerant compressor 100 having a housing 10 having a lower part 11 and a cover 12 . The lower part 11 and the cover 12 are each configured in the shape of a bowl. The cover 12 has a through-hole 12a into which the electrical connector 30 is placed in a hermetically sealed manner. The electrical connection 30 can be connected to a control unit not shown in the figures. Inside the housing 10 is arranged a piston pump 40 which is electrically connectable to the control unit via an electrical connection 30 . The connection piece 30 comprises on its outside and inside an electrical plug 31 with a steel socket body, wherein the electrical plug 31 has metal conductor pins 32 held by an electrically insulating material, in particular glass. The electrical connections can be conventional components.

Abstract

The invention relates to a hermetically sealed refrigerant compressor (100), comprising: a housing (10) having a lower part (11) and a cover (12), the cover (12) being connectable to the lower part (11); an electrical connection (30) passing through the housing (10); and a piston pump (40) arranged in the housing (10) and electrically connectable to the control unit via a connection (30). The cover (12) of the housing (10) has a through-opening (12a) in which the electrical connection element (30) is arranged. The housing (10) is configured such that, when the housing (10) is opened, the piston pump (40) can be placed into a cover (12) of the housing (10) and can be connected to the electrical connection (30).

Description

technical field [0001] The present invention generally relates to a hermetically encapsulated refrigerant compressor of the reciprocating piston compressor type, and more particularly to such a compressor for use in refrigerators, such as refrigerators, freezers and small air conditioners for domestic use electrical appliances. [0002] The invention also relates to a method for assembling such a refrigerant compressor. Background technique [0003] In the development of refrigerant compressors, there is a strong trend to keep the size of the compressor, especially its height, as small as possible. The reasons for this trend are manifold. For example, the chamber for the refrigerant compressor can be designed smaller in a refrigerator or freezer, whereby a larger useful volume can be obtained for the same appliance size refrigerator or freezer. Consistent with this trend, the housings of refrigerant compressors have to become increasingly compact, wherein for structural m...
