Description
[technical field]
This utility model relates to Compressor Technology, particularly relates to single syncline compressor disc.
[background technology]
Existing various types of compressor, is divided into reciprocating and rotary, wherein reciprocating compressor quilt generally
Be divided into crank-type, rotating sloping disk type and Wobble plate type compressor, and rotary compressor be divided into blade rotate and
Scroll compressor.Some compressor is because it can change volume and be referred to as variable displacement compressor.
In the compressor being typically used as vehicle air conditioner, mostly use swash-plate-type compressor, dish type
Wobbler is arranged in drive shaft with an inclination angle, receives with the engagement/disengagement selectively through electric clutch
Engine power or directly receive power to rotate from motor by drive shaft, and multiple piston is arranged on rotation
Turn the surrounding of swash plate and be inserted with slide block between which, with described being rotatably assorted and formed in the cylinder body
Make linear reciprocal movement in multiple cylinder-bore, thus cold-producing medium is sucked from vaporizer, compresses and towards condensation
Device discharges.
At present, swash-plate-type compressor is divided into that single direction rotation is inclined disc type and bidirectional swash cam type, unidirectional rotation
Turning oblique tray type compressor is driven piston to be compressed in side by wobbler, and bidirectional swash cam type compressor
Driven piston to be compressed in both sides by wobbler simultaneously.
The piston-type automobile air-conditioning compressor of existing fixed displacement generally includes bi-directional swash plate type and unidirectional shaking tray
Formula two kinds, during bi-directional swash plate type compressor work, power is passed to by belt and clutch by automobile engine

Aerofluxus, the plunger shaft air-breathing on the right;When piston moves right, the medium in the plunger shaft on the right compressed,
Aerofluxus, the plunger shaft air-breathing on the left side;The work process of compressor is realized by the effect of respective suction and discharge assembly.
Unidirectional Wobble plate type compressor is the belt by automobile engine and power is passed on main shaft by clutch, logical
Crossing main shaft drives the shaking tray being fixed on main shaft to rotate, and planet plate waves under the promotion of shaking tray, with planet plate phase
The connecting rod connected is connected piston with planet plate, along with waving of planet plate, drives piston at the piston of cylinder body
Chamber is made straight reciprocating motion, be provided with on the right of cylinder body one group by front diaphragm seal, suction valve chip, valve plate,
The suction and discharge assembly of exhaust valve plate, rear diaphragm seal composition.When piston plunger shaft air-breathing in time moving to left, when piston to
During right motion, the medium in plunger shaft is compressed, and realizes the worked of compressor by the effect of suction and discharge assembly
Journey.
Bidirectional piston type compressor is widely used so that its volume is little, but is bidirectional piston due to it, has at double
Number of cylinders, therefore capacity is relatively big, and upper and lower cylinder body requirement on machining accuracy is the highest, has two set suctions
Pneumatic module, therefore compressor is relatively costly.
