Technical field
The utility model is related to the structure that air conditioner compressed machine aided blade stretches out, and in particular to rotary-vane type air conditioning compressor helps leaf
The end plate structure that piece stretches out.
Background technology
Automobile air conditioner compressor is automotive air-conditioning system the inside for compressing and conveying the component of refrigerant gas.Vane
Formula compressor of air conditioner is the compressor of air conditioner that a kind of employing vane mechanism conveys power as gas.
In the automobile rotary blade type compressor being usually used at present, stretching out for blade mainly leans on what is produced after rotor rotation
The collective effect of centrifugal force and blade groove bottom high-pressure oil is realizing.At the compressor start initial stage, high pressure oil pressure is not yet effectively built
Vertical, blade can only stretch out under the influence of centrifugal force.During stretching out, the resistance to sliding of blade groove and the inertia force of blade etc.
Blade can be hindered, blade is stretched out slowly, and flutter is produced in blade notch, cacophonia causes the hydraulic oil of compressor
Pressure does not slowly build up, it is impossible to meet the use requirement of client.In extreme circumstances, the time that blade stretches out even can reach
By more than 30 seconds.During this period of time, the operating pressure of rotary blade type compressor is unstable, and the blade for partly stretching out produces flutter and makes an uproar
Sound.The blade for how making rotary blade type compressor quickly stretches out, and rotary blade type compressor quick and stable is normally run, and is always stranded
Disturb a difficult problem for compressor of air conditioner industry.
Utility model content
The purpose of this utility model is to be directed to the deficiencies in the prior art, there is provided a kind of automobile rotary-vane type air conditioning compressor helps leaf
The end plate structure that piece stretches out, at the compressor start initial stage, in exhaust while rotation using vane mechanism in cylinder working chambers
End forms certain oil pressure, and the blade that can help rotary blade type compressor quickly stretches out, and then rotary blade type compressor is quickly normally transported
OK.
To solve above-mentioned technical problem, the utility model employs following technical scheme：
Automobile rotary-vane type air conditioning compressor helps the end plate structure that blade stretches out, including rotary blade type compressor, Spiralism type pressure
Cylinder body is provided with contracting machine, the inner chamber of cylinder body is that class is oval, and rotor is provided with oval chamber, and rotor is rotary to be supported in cylinder
The forward and backward end plate that body two ends are arranged, the periphery of rotor is provided with multiple telescopic blades, and the plurality of blade slides match somebody with somebody respectively
Close in set blade groove on rotor, the bottom oilhole of the blade groove is connected with the logical oil groove arranged on forward and backward end plate,
The logical oil groove of the end plate is bowtie shaped slot, is arranged on the middle part of end plate, check valve is additionally provided with the middle part of end plate, unidirectionally
One end of valve connects with bowtie shaped slot, and the other end is connected with cylinder body high pressure gas hole.
Preferably, the bowtie shaped slot has two inclined oil hole of air, and the check valve includes a less spring installation cavity and
Individual larger steel ball installation cavity, is provided with spring in spring installation cavity, the steel abutted against with spring is provided with steel ball installation cavity
Ball, spring installation cavity and steel ball installation cavity transition position are provided with the taper surface being engaged with steel ball, and steel ball installation cavity is away from spring
One end connects with cylinder body high pressure gas hole, and spring installation cavity is connected away from one end of steel ball with bowtie shaped slot.
Preferably, at the compressor start initial stage, blade in when just stretching out state, install by the inclined oil hole of air and check valve
Chamber is just at root of blade.
The beneficial effect that the utility model reaches：
By arranging bowtie shaped slot and check valve on end plate, when the compressor start initial stage, blade is in will just stretch out shape
During state, steel ball and the taper surface of check valve depart from, and now the gas in exhaust passage flows to bowtie shaped slot and just acts on by valve opening
Certain oil pressure is formed in exhaust end in very short time while vane mechanism rotates in root of blade, cylinder working chambers, the oil
Steel ball in check valve is pressed to and formed on taper surface sealing by pressure, it is to avoid pressure release, adds the oil pressure for being simultaneously from inclined oil hole of air so that
Blade can quickly stretch out at the compressor start initial stage, ensure that compressor quick smoothly runs then.

Explanation.
As shown in Figures 1 to 4, automobile rotary-vane type air conditioning compressor helps the end plate structure that blade stretches out, including Spiralism type
Compressor, is provided with cylinder body 1 in rotary blade type compressor, the inner chamber of cylinder body is that class is oval, and rotor 2, rotor 2 are provided with oval chamber
It is concentric with the inner chamber of cylinder body 1, the rotary front end-plate 3 and end plate 4 for being supported in the setting of cylinder body two ends of rotor 2, rotor 2
Periphery is provided with multiple telescopic blades 6, and the rotation rear blade 6 of rotor 2 stretches out under the action of the centrifugal force, the external part of blade 6
Be close to cylinder body 1, multiple blades 6 are slidably fitted in respectively in blade groove 5 set on rotor, the bottom oilhole of blade groove 5 with
Front end-plate 3 is connected with the logical oil groove arranged on end plate 4, and the logical oil groove of end plate 4 is bowtie shaped slot 7, in being arranged on end plate 4
Portion, at the middle part of end plate 4 check valve 8 is additionally provided with, and the quantity of check valve 8 is one, and one end and the bowtie shaped slot 7 of check valve 8 connect
