The variable valve is characterized by further comprising a valve needle and an ejector rod, wherein the ejector rod penetrates through the iron core, one end of the ejector rod is abutted to the ejector rod sat, the other end of the ejector rod is abutted to the valve needle, the other end of the valve needle is abutted to a corrugated tube mounted in the valve seat, a boss is arranged on the valve needle, a first spring is mounted at a position, close to the boss, on the valve needle, a second spring is arranged between the guiding sleeve and the ejector seat, and an air vent is arranged at the tail of the valve needle. The variable valve has the advantages of low manufacturing precision, low process cost, simplicity in assembly and smoothness in exhaust.
Description
Technical field
The utility model relates to a kind of automobile air conditioner compressor and uses accessory, relates in particular to the variable valve that a kind of car air conditioner positive displacement compressor is used.
Background technique
In the existing technology, need link together through link between any two between original tip-lever support, needle and the push rod of variable valve, assembling is complicated; Coaxality requires high in the time of assembling; Accuracy of manufacturing requires height, technology cost height, and former exhaust port is arranged on the link between thimble and push rod and the needle, and exhaust effect receives the influence of the degree of accuracy of its assembling; If assembling is not accurate, can cause its exhaust to have some setbacks.
Summary of the invention
The purpose of the utility model is to provide a kind of accuracy of manufacturing low, and assembling is simple, and exhaust is the variable valve smoothly.
In order to achieve the above object, first kind of technological scheme of the utility model is: a kind of variable valve comprises housing, coil base, iron core and valve seat; Hookup wire ring support in the said housing is set with guide sleeve in the coil base, have tip-lever support and iron core in the guide sleeve; Its innovative point is: also comprise needle and push rod, said push rod passes an iron core and an end and tip-lever support and offsets, and the other end and the needle of push rod offset; The other end of needle offsets with the bellows that is contained in the valve seat, and said needle is provided with boss, and near the boss place first spring is housed on the needle; Have second spring between said guide sleeve and the tip-lever support, said needle afterbody has vent.
Has seal ring between said housing and the guide sleeve.
Said valve seat outer wall is set with filter screen.
Has tight fixed ring between said housing and the iron core.
In order to achieve the above object, the another kind of technological scheme of the utility model is: a kind of variable valve comprises housing, coil base, iron core and valve seat; Hookup wire ring support in the said housing is set with guide sleeve in the coil base, have tip-lever support and iron core in the guide sleeve; Its innovative point is: also comprise needle and push rod, said push rod passes an iron core and an end and tip-lever support and offsets, and push rod and needle are structure as a whole; The other end of needle offsets with the bellows that is contained in the valve seat, and said needle is provided with boss, and near the boss place first spring is housed on the needle; Have second spring between said guide sleeve and the tip-lever support, said needle afterbody has vent.
Has seal ring between said housing and the guide sleeve.
Has tight fixed ring between said housing and the iron core.
After adopting above-mentioned first kind of structure,, do not need link to connect owing to be that branch is arranged between tip-lever support, needle and the push rod; Relatively all be to work separately, can not disturb each other, only adopt first spring three to be cooperatively interacted and be in the same place with second spring; Need not consider the coaxality problem in the time of assembling, satisfy under the situation of original designing requirement that the structure accuracy of manufacturing of the utility model is low; The technology cost is low, and assembling is simple, and exhaust only need be established vent at the needle afterbody now; Saved the discharge portion of link, so exhaust structure is simple and exhaust is smooth and easy; Same, adopt another kind of technological scheme, exhaust only need be established vent at the needle afterbody, so exhaust structure is simple and exhaust is smooth and easy, and it is low that push rod and needle are made of one accuracy of manufacturing.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the another kind of structural representation of the utility model.
Embodiment
The embodiment who provides below in conjunction with accompanying drawing does further detailed explanation to the utility model.
As shown in Figure 1, a kind of variable valve of the utility model comprises housing 1, coil base 2, iron core 4 and valve seat 6; Hookup wire ring support 2 in the said housing 1 is set with guide sleeve 3 in the coil base 2, have tip-lever support 5 and iron core 4 in the guide sleeve 3; Also comprise needle 7 and push rod 9, said push rod 9 passes an iron core 4 and an end and tip-lever support 5 and offsets, and the other end of push rod 9 and needle 7 offset; The other end of needle 7 offsets with the bellows 8 that is contained in the valve seat 6, and said needle 7 is provided with boss 7-2, and near boss 7-2 place first spring 10 is housed on the needle 7; Have second spring 11 between said guide sleeve 3 and the tip-lever support 5, said needle 7 afterbodys have vent 7-1.
Has seal ring 12 between said housing 1 and the guide sleeve 3.
Said valve seat 6 outer walls are set with filter screen 13.In order to prevent that external dust from getting into.
Has tight fixed ring 14 between said housing 1 and the iron core 4.
As shown in Figure 2, certainly, can also adopt another kind of structure, only be that with the distinctive points of said structure push rod 9 is structure as a whole with needle 7.
The utility model does not need link to connect owing to be that branch is arranged between tip-lever support 5, needle 7 and the push rod 9, relatively all is to work separately; Can not disturb each other, only adopt first spring 10 three to be cooperatively interacted and be in the same place, need not consider the coaxality problem in the time of assembling with second spring 11; Satisfying under the situation of original designing requirement, the structure accuracy of manufacturing of the utility model is low, and the technology cost is low; Assembling is simple; And exhaust only need be established vent at the needle afterbody now, saved the discharge portion of link, so exhaust structure is simple and exhaust is smooth and easy.
