Embodiment Construction

[0018] FIG. 1 shows a refrigerant compressor 1 with a motor 2 driving a compressor 3 . The motor 2 has a stator 4 and a rotor 5 . The rotor 5 is connected to a shaft 6 , which drives a piston 8 in a cylinder 9 via a crankshaft 7 . The cylinder 9 is closed by a cylinder head 10, in which are placed valves in a manner known per se, which respectively control the operation of filling the compression chamber in the cylinder 9 with refrigerant gas, or transferring the refrigerant gas from the compressed Operations that discharge from the chamber.

[0019] The aforementioned components are enclosed in a housing 11 which seals the motor 2 and the compressor 3 . An electronic connection device 12 is provided on the outside of the housing, and if necessary, it has a controller, which controls the operation of the motor 2 according to a predetermined value, such as the cooling requirement of the refrigerator, which is not described in detail here. show. The device 12 is connected to...

Abstract

The invention concerns a refrigerant compressor with a motor, a compressor driven by the motor, and a muffling device having at least one muffler with a housing. It is endeavoured to reduce the thermal influence of suction gas in the refrigerant compressor. For this purpose, it is ensured that the housing has at least one outer wall, which is made of a foamed plastic.

Description

technical field [0001] The invention relates to a refrigerant compressor with a motor, a compressor driven by the motor, and a sound attenuation device having at least one sound attenuator with a housing. Background technique [0002] Such a refrigerant compressor is known, for example, from patent DE 195 16 811 C2. Here, the motor and compressor are located in a housing together with a suction muffler. That is, what is involved is a hermetic refrigerant compressor which has proven its worth over the past few years. [0003] With this type of compressor, refrigerant gas from the evaporator is drawn in, compressed in a compressor designed to increase the temperature of the refrigerant gas, and passed through a discharge nozzle which in many cases communicates with a shock muffler emission. In this connection, the cooler the refrigerant suction gas is, the more efficient the compressor will be. However, the temperature of the refrigerant suction gas has increased before en...
