Description
Technical field
The present invention relates to automobile air conditioner compressor, is a kind of detachable automobile air condition compressor.
Background technique
Automobile air conditioner compressor is the heart of automobile air conditioning system, plays a part compression and refrigerant conveying steam.Notice of authorization CN201448222U like Chinese patent document publication; May 5 2010 notice of authorization day; The model utility name is called " sealing configuration between the automobile air conditioner compressor cylinder body "; This model utility key points in design is to be provided with rubber gasket between the end face of protecgulum, front-bank rotor housing, rear-bank rotor housing and bonnet relative engagement, and the end surface shape of rubber gasket respectively is connected end surface shape with cylinder body and is complementary.Form convex tendon along rubber gasket end face excircle.Rubber gasket is a three-decker, and the mesosphere is a steel plate, and two ends are rubber layer.Through this kind structure, improved sealing, reduced interior leakage, improved the performance of compressor.Thereby this patent has been set forth a kind of compressor overall tightness that improves and has been reduced the method for leaking in the compressor, though can reduce interior leakage to a certain extent, is difficult to thoroughly solve the problem of leaking in producing.
Existing automobile air conditioner compressor mostly adopts the split-type structural of front-bank rotor housing and rear-bank rotor housing; And the hyperbaric chamber of front end housing is to communicate through inner chamber of cylinder block with the hyperbaric chamber of back cylinder cover; And inner chamber of cylinder block also is divided into front-bank rotor housing inner chamber and rear-bank rotor housing inner chamber; This just makes the sealing station of front-bank rotor housing inner chamber and rear-bank rotor housing inner chamber seepage occur, and the high pressure-temperature gas of seepage gets into air-inlet cavity, causes the low-temp low-pressure gas of air-inlet cavity to produce expansion; Gas volume in the inlet casing is reduced, and the refrigerating capacity of air condition compressor reduces.High-pressure channel and the low pressure chamber in the front and rear cylinder in traditional front and rear cylinder are isolated; High-pressure channel is connected by the front and rear cylinder plane; Do not take the effective seal measure, high temperature, pressurized gas easy to leak cause that the gas density in the low pressure chamber reduces to low pressure chamber; The gas volume that gets in the cylinder is reduced, directly influence the volumetric efficiency and the refrigeration of compressor.Front-bank rotor housing inner chamber and rear-bank rotor housing inner chamber are tightly connected fully, and this is difficult the realization, and quite high to the technical requirements of Sealing.From existing technology, also do not find to have the scheme that addresses this problem.
Summary of the invention
For overcoming above-mentioned deficiency; The objective of the invention is provides a kind of detachable automobile air condition compressor to related domain; Make it solve the high temperature and high pressure gas infiltration air-inlet cavity of existing like product because of inner chamber of cylinder block; Cause the low-temp low-pressure gas of air-inlet cavity to expand the technical problem that the air condition compressor refrigerating capacity reduces.Its objective is and realize through following technological scheme.
A kind of detachable automobile air condition compressor; This compressor comprises front end housing, exhaust valve plate, air-intake valve plate, cylinder body, back cylinder cover, transmission shaft, swash plate, and cylinder body comprises front-bank rotor housing, rear-bank rotor housing, is connected the front exhaust valve plate between front end housing and the front-bank rotor housing; Be connected the final vacuum valve plate between back cylinder cover and the rear-bank rotor housing; Hyperbaric chamber before front end housing and the sealing of front exhaust valve plate constitute, back cylinder cover and the sealing of final vacuum valve plate constitute the back hyperbaric chamber, and front-bank rotor housing is provided with suction port; Back cylinder cover is provided with relief opening, and relief opening connects the back hyperbaric chamber.Its main points are to be connected by high-voltage tube between said preceding hyperbaric chamber and the back hyperbaric chamber, and high-voltage tube passes inner chamber of cylinder block, and an end and preceding hyperbaric chamber are connected, and the other end is connected with the back hyperbaric chamber.The inner chamber of cylinder block that is replaced original automobile air conditioner compressor by high-voltage tube independently is as the gas exchange passage between preceding hyperbaric chamber and the back hyperbaric chamber; Not only solve former inner chamber of cylinder block and adopted the leakage problems that is sealed and matched and is produced; And high-voltage tube can to prevent that the inner chamber of cylinder block temperature from raising too fast, the low-temp low-pressure gas that effectively reduces in the air-inlet cavity receives the inner chamber of cylinder block Influence of Temperature.
The concrete high-voltage tube plan of establishment has:
Scheme one: said front-bank rotor housing, rear-bank rotor housing are provided with the through hole that connects high-voltage tube, after high-voltage tube passes through hole, and the high-voltage tube one end front exhaust valve plate that is tightly connected, the other end final vacuum valve plate that is tightly connected.Adopt independently high-voltage tube structure, be convenient to repair and replacement.
Scheme two: one of them exhaust valve plate integrated high voltage pipe of said front exhaust valve plate, final vacuum valve plate, front-bank rotor housing, rear-bank rotor housing are provided with the through hole that connects high-voltage tube, and high-voltage tube passes through hole and another exhaust valve plate is tightly connected.Adopt high-voltage tube and exhaust valve plate integrated, can improve the sealing between high-voltage tube and the exhaust valve plate.
Scheme three: one of them integrated high voltage pipe of said front-bank rotor housing, rear-bank rotor housing, another is provided with the through hole that connects high-voltage tube, and high-voltage tube one end and front exhaust valve plate are tightly connected, and the other end and final vacuum valve plate are tightly connected.Adopt high-voltage tube and front-bank rotor housing or rear-bank rotor housing integrated, can improve the structure stability of high-voltage tube.
Said high-voltage tube is provided with at least one.
The present invention adopts independently high-voltage tube, has solved original automobile air conditioner compressor inner chamber of cylinder block easy to leak, and the inner chamber of cylinder block temperature raises and to influence the technical problem of air-inlet cavity gas volume, has improved the admission space and the refrigerating capacity of automobile air conditioner compressor.Be suitable as the architecture advances of existing like product, apply.
