Abstract
The utility model relates to the technical field of auto air conditioning compressors, in particular to an improved aluminum alloy control valve for a piston type auto air conditioning compressor, which is characterized in that the diameter d of an aluminum alloy housing lid of the control valve is 21.5 mm. Compared with the prior art, the improved aluminum alloy control valve is made of aluminum alloy, and the thickness of the aluminum alloy housing lid is increased, so that the weight is reduced, the cost is lowered, and the problem that copper content is over the standard can be avoided further.
Description
[technical field]
The utility model relates to the automobile air conditioner compressor technical field, specifically a kind of aluminum alloy control valve of improved piston-type automobile air-conditioning compressor.
[background technique]
Control valve is the core component of variable compressor.Control valve is induced compression machine high pressure (exhaust cavity), low pressure (low-pressure cavity), cavity pressure simultaneously.Exhaust pressure, pressure of inspiration(Pi), cavity pressure interact to produce on control valve and make a concerted effort, and the aperture of adjusting control valve is controlled exhaust, and is air-breathing, cavity pressure size, thereby control swash plate angle of inclination.
The piston type Control Valve in Variable Displacement Compressor adopts the brass alloys shell usually, and cost is higher, and there is certain limitation in a lot of at present country to copper content.
[summary of the invention]
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of control valve of aluminum alloy casing is provided, and has solved the control valve cost height of brass alloys shells, the problem that copper content exceeds standard easily.
In order to achieve the above object, the utility model has designed a kind of aluminum alloy control valve of improved piston-type automobile air-conditioning compressor, it is characterized in that: the diameter of the aluminum alloy casing lid of control valve is d=21.5mm.
The utility model is compared with prior art, adopts aluminum alloy material, and increases the thickness of aluminum alloy casing lid, and weight saving, cost reduce, and have more avoided the problem of copper content overproof.
[description of drawings]
Fig. 1 is a structural representation of the present utility model.
Referring to Fig. 1,1 is the aluminum alloy casing lid.
[embodiment]
Now in conjunction with the accompanying drawings the utility model is described further.
Be illustrated in figure 1 as structural representation of the present utility model, the diameter of aluminum alloy casing lid 1 of the present utility model is d=21.5mm.Existing piston formula Control Valve in Variable Displacement Compressor adopts the brass alloys shell usually, and cost is higher, and now a lot of country all limits copper content.Shell of the present utility model adopts aluminum alloy material, and weight saving is a lot, and does not have the restriction of copper content overproof, and cost is also lower; But because aluminum alloy material is softer, yielding, so need to increase the thickness of aluminum alloy casing lid, promptly the diameter d of aluminum alloy casing lid is increased to 21.5mm by original 21.1mm.
