Abstract
The invention discloses an inclined compressor piston cylinder. The inclined compressor piston cylinder comprises a cylinder body and an outer contour body; the outer contour body and the cylinder body are integrally molded through casting; the cylinder body is cylindrical; a through hole is in the center position; multiple independent piston cylinders with two communicated ends are uniformly arranged around the through hole; the piston cylinders include piston travel spaces in middle and compression spaces at two ends; the diameters of the piston travel spaces are 1.1-1.5 times of the diameters of the compression spaces; the outer contour body is used for mounting and fixedly connecting with other parts of a compressor; and the outer contour body and the cylinder body are aslant arranged. The inclined compressor piston cylinder is simple in structure and easy to assemble, uses a gap type groove channel for enabling a valve piece to join with the groove channel only by a tongue-shaped elastic piece with smaller area, realizes one-way circulation, and can retain the root part of the elastic piece with larger area to achieve higher elastic strength.
Description
Technical field
The invention belongs to automobile air conditioner compressor technical field, particularly relate to the stability techniques under automobile air conditioner compressor bad working environments and improve.
Background technology
Along with the development of automobile manufacture industry, the research of automobile air conditioning technology is more and more faster.Automobile air conditioner compressor is core component therein, and automobile air conditioner compressor generally uses swash plate round piston to be compressed, and swash plate high speed rotating is up to 3000 turns/min, and therefore wearability requires the highest.Swash plate in compressor of air conditioner generally uses split type at present, motor is i.e. had to drive the part rotated to use cast iron or rustless steel to make in the middle part of swash plate, the ring shoulder (because high speed rotating and miscellaneous part rub) of swash plate excircle then uses copper alloy, and prepares chromium-molybdenum alloy layer at copper alloy surface thus improve its wearability.Adopting swash plate cost in this way the highest, the only cost of ring shoulder is accomplished by dozens of yuan, and owing to using split-type structural, therefore intensity is limited the most easily occurs that abrasion deviation causes the life-span short.
Piston cylinder is as the vitals of compressor, its reliability is most important to the stability of compressor, current piston cylinder assembling is relatively difficult, and air-breathing and aerofluxus are promoted by piston rod and realize, if the air-breathing of open type and aerofluxus, easily make the damage of valve plate part relatively big, and valve plate through hole needs to mate with piston cylinder, cause clear size of opening excessive, and then valve block intensity is declined.
Summary of the invention
Goal of the invention: for the problem and shortage of above-mentioned existing existence, it is an object of the invention to provide a kind of inclinaple press machine piston cylinder, simple in construction, it is easily assembled, and by the recess channels of gap type, make valve block only need the tongue shape shell fragment of less area and recess channels to take patch, it is achieved one-way flow, so can retain greater area of shell fragment root thus there is higher elastic strength.
Technical scheme: for achieving the above object, the present invention is by the following technical solutions: a kind of inclinaple press machine piston cylinder, including cylinder body and outline body, described outline body and cylinder body are integrated casting, described cylinder body is cylindrical shape, center is the through hole run through, it is evenly arranged with the piston cylinder that multiple independent two is through around this through hole, described piston cylinder includes piston stroke space and the compression stroke at two ends of centre, and the diameter in described piston stroke space is 1.1～1.5 times of compression stroke diameter；Described outline body is for installing affixed with compressor miscellaneous part, and described outline body and cylinder body are for being obliquely installed.
As preferably, the compression stroke at described piston cylinder two ends includes cylindrical space and the recess space arranged on cylindrical space inwall.
Accompanying drawing explanation
Fig. 1 is the structural representation of inclinaple press machine piston cylinder of the present invention.
Wherein, cylinder body 1, outline body 2, piston cylinder 3, recess space 4.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment, it is further elucidated with the present invention, it should be understood that these embodiments are merely to illustrate the present invention rather than limit the scope of the present invention, after having read the present invention, those skilled in the art all fall within the application claims limited range to the amendment of the various equivalent form of values of the present invention.
As shown in Figure 1, a kind of inclinaple press machine piston cylinder, including cylinder body and outline body, described outline body and cylinder body are integrated casting, described cylinder body is cylindrical shape, and center is the through hole run through, and is evenly arranged with, around this through hole, the piston cylinder that multiple independent two is through, described piston cylinder includes piston stroke space and the compression stroke at two ends of centre, and the diameter in described piston stroke space is 1.1～1.5 times of compression stroke diameter；Described outline body is for installing affixed with compressor miscellaneous part, and described outline body and cylinder body are for being obliquely installed.
As preferably, the compression stroke at described piston cylinder two ends includes cylindrical space and the recess space arranged on cylindrical space inwall.
By arranging with profile angled manner, can be directly arranged on the whole by what profile body tilted when mounted.It addition, on the one hand being relatively large in diameter of piston stroke space avoid overcompression, on the other hand compression ratio can be improved；The valve block that the setting of recess space is simultaneously only needs less contact surface, more multizone can improve the elastic strength of valve block.
