Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment the invention will be further described.
Embodiment 1
See Fig. 2-Fig. 7, the liquid storage structure of this rotary compressor, it is provided with motor 2 and compressor in the housing 1 of compressor
Structure 3, motor 2 is connected with the bent axle 4 in compression mechanism 3, this compression mechanism 3 includes cylinder 5, the piston 8 that is accommodated in cylinder 5,
Piston 8 is driven to make the bent axle 4 of eccentric rotary and support base bearing 6 and supplementary bearing 7, base bearing 6 He of bent axle 4 by eccentric shaft
Supplementary bearing 7 is arranged on cylinder 5, and the end face of piston 8 and base bearing 6, supplementary bearing 7 are positioned at the end face of cylinder 5 respectively in gap
Contact and relatively slide, cylinder 5 being provided with vane slot 5.3 and for installing the suction tube installing hole 5.1 of suction tube 9.
Being provided with liquid storage cylinder 10 on cylinder 5, one end of liquid storage cylinder 10 communicates with suction tube 9, the other end of liquid storage cylinder 10 with
The cylinder air inlet 5.2 of compression mechanism communicates；Suction tube installing hole 5.1 and cylinder air inlet 5.2 are positioned at the same of vane slot 5.3
Side.The airflow direction of suction tube installing hole 5.1 and cylinder air inlet 5.2 is the most on the same line.Cylinder air inlet 5.2 minimum
Position is higher than the bottom surface of liquid storage cylinder 10.Liquid storage cylinder 10 is by the end face of flange widened on the deep gouge arranged on cylinder 5 and base bearing 6
Jointly seal formation.
The coolant of the gas-liquid mixing that rotary compressor sucks, is shown in the arrow M in Fig. 4, is flowed on cylinder 5 by suction tube 9
The liquid storage cylinder 10 arranged, owing to the airflow direction of suction tube installing hole 5.1 and cylinder air inlet 5.2 is not arranged on the same straight line be,
Liquid refrigerants can flow to liquid storage cylinder by the arrow 0 along Fig. 4 based on inertia, gaseous coolant then can arrow N along Fig. 4 directly or
In the roundabout compression chamber being inhaled into cylinder 5, it is possible to the coolant avoiding gas-liquid to mix is directly entered in the compression chamber of cylinder 5, causes
Hydraulic compression.Simultaneously as the extreme lower position of cylinder air inlet 5.2 is higher than the bottom surface of liquid storage cylinder 10, see the height H institute in Fig. 6
Showing, thus defining a space with a constant volume in liquid storage cylinder 10 bottom, liquid refrigerants can be deposited on liquid storage cylinder 10
