Problems solved by technology

At the same time, a stream of high-pressure refrigerant flows back into the compression chamber 11, so that the actual volume displaced by the piston decreases, resulting in a phenomenon of low refrigeration capacity.
[0021] When this phenomenon of low cooling capacity occurs, the efficiency of the compressor decreases and power consumption increases, and at the same time causes a problem that the cooling capacity of the refrigerator equipped with this compressor is weakened

Embodiment

[0040] The container 101 is equipped with an exhaust pipe 102 and an air suction pipe 103, both of which are connected to a cooling system (not shown); at the bottom thereof, organic oil 104 is stored; inside it is housed an electric component 107, which comprises a stator 105 and a rotor 106, and a compression mechanism 108 rotationally driven by an electric component 107. The container 101 is filled with refrigerant 109 .

[0041] Due to environmental problems in recent years, it is preferable that the refrigerant 109 has nothing to do with chlorofluorocarbons (CFCs), but refrigerants such as R134a and R600a are used.

[0042] Next, the main components of the compression mechanism 108 will be described.

[0043] The cylinder 110 is equipped with a substantially cylindrical compression chamber 111 and a bearing portion 112 . Of the two sides of the valve plate 113 , the side opposite to the contact with the cylinder 110 is equipped with an exhaust valve device 114 to close ...

Abstract

A hermetic compressor that has a pedestal of the valve plate to which a discharge reed equipped with an opening / closing part and discharge reed holding part, a spring reed equipped with a movable part and spring reed holding part, and a stopper equipped with a regulation part and stopper holding part, are fixed in this sequence, and also has a discharge valve device in which the spring reed is shaped in a substantially crank-like form is provided. A space is formed between the movable part of the spring reed and the opening / closing part of the discharge reed, and both are not adsorbed each other, thus preventing a delay in closing of the discharge reed. This makeup suppresses a decrease in freezing capacity of a fridge-freezer device and the like, thus implementing higher efficiency.

Description

technical field [0001] The present invention relates to a hermetic compressor for refrigerators and the like. Background technique [0002] Japanese Patent Laid-Open Application No. 2002-195160 discloses an example of a conventional hermetic compressor (hereinafter referred to as "compressor"). That is, a compressor equipped with a discharge valve device for reducing noise during operation and loss when opening / closing a discharge reed to improve energy efficiency. [0003] Below, refer to Figures 7 to 10 , describe this conventional compressor. Figure 7 is a cutaway view of a conventional compressor; Figure 8 is a top view of a conventional compressor; Figure 9 is a side sectional view of a discharge valve arrangement of a conventional compressor; Figure 10 is an exploded view of the discharge valve assembly of a conventional compressor. [0004] An airtight container (hereinafter referred to as "the container") 1 is equipped with an exhaust pipe 2 and a suction p...
