Abstract
The invention relates to the technical field of refrigeration compressors, in particular to a variable displacement rotary compressor. In the variable displacement rotary compressor, a cylinder component is provided with a reflux inlet communicated to the chamber of an air cylinder; the reflux inlet is communicated to an air sucking-in area by a reflux passage arranged on the cylinder component; when the air cylinder works, under the action of the reflux inlet and the reflux passage which are arranged on the cylinder component, a compression chamber is communicated with the air sucking-in areaby the reflux passage when the compressor conducts initial compression; when an eccentric roller is disengaged from a reflux termination angle Theta, effective air compression can be conducted; therefore under the condition that the dimensions of the cylinder component and existing processes are not changed, only the arrangement of the reflux inlet and the reflux passage at proper positions can change the effective air compression amount of the compressor and the type of the needed compressor without changing a present cast mould or a frock clamp. In addition, the variable displacement rotarycompressor has short production period and reduces the production cost.

Rotary compressor is in when work, and under the constant situation of other situation, the effective pressurized gas scale of construction in the compression chamber has been determined the power consumption of compressor electric motor, and effectively the discharge gas flow of the pressurized gas scale of construction and compressor is closely related; For reaching rational coupling, when needing the different model compressor of different displacements, present common practice is: the upper and lower flange that produces the cylinder of different model again and match; Make the cylinder and the upper and lower flange of new model and need offer casting mould again, make all frock clampings again, the cycle is long, cost is high.
Summary of the invention
Of the present invention is to cause the problem that the cycle is long, processing cost is high at need after present rotary compressor model change die sinking again and frock clamping, and a kind of variable displacement rotary compressor that overcomes the above problems is provided.
For reaching above purpose, adopt following technological scheme:
A kind of variable displacement rotary compressor, the housing assembly of described rotary compressor includes upper flange, lower flange and cylinder, and upper flange, lower flange are arranged on the cylinder two ends and enclose the sealing cylinder chamber; Described housing assembly is provided with the refluxing opening that is communicated in the cylinder chamber, and refluxing opening is communicated to the gas suction area by the return flow line that is arranged on the housing assembly.
Intakeport that wherein said gas suction area is a compressor and permanent air aspiration cavity.
Wherein said refluxing opening is arranged on upper flange.
Wherein said refluxing opening is arranged on the cylinder.
Wherein said refluxing opening is arranged on the lower flange.
Eccentric roller was backflow end angle θ with the angle of slide plate on sense of rotation when the eccentric roller rotation of wherein said rotary compressor made compression chamber just break away from refluxing opening, and the span of θ is 90 °≤θ≤200 °.
Wherein said backflow end angle θ is 130 °.
Beneficial effect of the present invention is: a kind of variable displacement rotary compressor of the present invention, described housing assembly upper flange or lower flange or cylinder are provided with the refluxing opening that is communicated in the cylinder chamber, and refluxing opening is communicated to the gas suction area by the return flow line that is arranged on the housing assembly; Cylinder is when work, be arranged under the effect of the refluxing opening of housing assembly and return flow line, compressor compression chamber when initial compression is connected by the return flow line with the gas suction area, just carries out effective pressurized gas when eccentric roller breaks away from backflow end angle θ; Therefore, need not change under the situation of cylinder assembly size and ready-made processing technology, only need offer refluxing opening and return flow line in position, can change the available gas decrement of compressor, change over desired compression machine model, need not to change ready-made casting mould and frock clamping, the manufacturing cycle shortens, reduces fabricating cost.
