Description
Technical field
The present invention relates to vehicle compressor external control valve gear more particularly to a kind of compressor with variable displacement external controls
Valve belongs to automobile air conditioner compressor technical field.
Background technique
In order to save limited energy consumption and improve the comfort requirement of air conditioning for automobiles, the rotation using outside control is oblique
Disk variable compressor is just gradually becoming the first choice of car manufacturer, is that automobile and motor vehicle air conditioning are realized energy-saving and emission-reduction, changed
The primary hand that kind temperature adjusts, reduces air conditioner noises, reduces engine operation load, reducing the functions such as engine fuel consumption
Section.And the technology for realizing that compressor becomes discharge capacity has Pneumatic valve (internally piloted valve) and external control valve (external control valve) two inside compressor
Kind, the application technology of outer control valve therein leads over internally piloted valve and gradually forms mainstream, such as Patent No.
Compressor with variable displacement control valve disclosed in the utility model patent of CN20152081404.5, outer control valve mainly by
The major parts such as valve body, valve rod, pressure element (bellows), reset spring, electromagnet (coil, sound iron core) composition, pressure-sensitive
For element for experiencing air-breathing cavity pressure, the valve seat of valve rod and valve body forms valve port, the both ends of valve rod respectively with dynamic iron core component and
Bellows is in contact, and valve rod is equipped with reset spring, and after coil is powered, dynamic iron core component is just generated to be moved to valve port closing direction
Dynamic thrust, as air-breathing cavity pressure Ps high, bellows, which is pressurized, to be shunk, then in bellows and dynamic iron core component collective effect
Under force valve port to be closed, when air-breathing cavity pressure Ps is low, bellows by internal spring force act on and expand, valve port opening, swash plate
Cavity pressure Pc is increased, and compression travel is made to become smaller, and discharge capacity reduces；Valve port flow is bigger, and pressure rises faster, and compressor slanting plate is to small
The response speed of angle direction adjustment is faster.It can be seen that external control valve is exactly according to the above input current value and air-breathing cavity pressure
Principle come realize compressor air-discharging amount variation and temperature adjust purpose.
In the use process of air conditioning for automobiles, air-conditioning duct internal system can be accumulated gradually from external worlds such as air, road surfaces
The impurity of environment, partial impurities can be entered in compressor chamber body by the control channel of external control valve.These impurity can be with pressure
The reciprocating motion of moving component, enters in the gap of moving component in contracting machine cavity body, wherein lesser impurity may aggravate
The abrasion of moving component (such as piston) causes leakage to increase, refrigeration effect decline；Biggish impurity may result in moving component
There is the unsmooth or even moving component of movement and kills, to influence the normal operation of automotive air-conditioning system in clamping stagnation.
Summary of the invention
It is an object of the invention to overcome existing vehicle compressor external control valve structural impurities poor filtration effect, easy failure lack
It falls into, proposes a kind of compressor with variable displacement control valve, impurity is stopped to enter compressor cavity by the control channel of external control valve
Probability delays to lead to the abrasion between moving component because of impurity, and reduce causes compressor to be killed because impurity enters in compressor chamber body
Risk, to extend the service life of compressor.
Technical solution of the invention: compressor with variable displacement external control valve, structure include coil block, dynamic iron core
Component, fixed core, guide sleeve, shell, valve rod, A filter, valve body and B filter；Wherein coil block is installed on the top of shell
Portion, dynamic iron core component and fixed core are installed on inside guide sleeve, and guide sleeve is installed in enclosure interior cavity, and valve body is installed by valve rod
In the bottom of shell；The on both sides of the middle Pd entrance of valve body is equipped with A filter, and the outlet the bottom Pc outside of valve body is equipped with B and filters
Device.
Preferably, the bottom of the shell is equipped with a circle groove, is equipped with No. 1 O-ring in groove；Outside the valve body
Portion is equipped with No. 2 O-rings and No. 3 O-rings from top to bottom；The outside of the valve rod is cased with reset spring；The valve body it is interior
Portion is equipped with bellows, the bottom end connection of bellows and valve rod.
Preferably, a circle step structure, the hole of the filter are provided with above the exit Pc of the valve body
Mouth is equipped with a circle buckle, and filter is linked together by the step of buckle and valve body.
Advantages of the present invention:
1) by the way that A filter is arranged as coarse filtration in external control valve Pd entrance, the biggish impurity of blockage size enters external control valve, can
It avoids causing entrance flow resistance excessive because the filtering accuracy of filter is excessively high, underfed, to guarantee the normal work of compressor；
2) by the way that B filter is arranged as essence filtering in the exit Pc of external control valve, the part of external control valve filter will can be flowed through
Impurity obstruction is intracavitary in the Pc of external control valve, effectively reduces abrasion aggravation, clamping stagnation or the risk killed between compressor moving component,
Extend the service life of compressor.
