Abstract
The utility model discloses a valve plate of an automobile air-conditioning compressor, which comprises a round plate, wherein an air intake and an exhaust hole are arranged in the round plate, when the valve plate is installed, the side of the round plate, which faces a piston of the automobile air-conditioning compressor, is the inner side of the valve plate, the other side of the round plate is the outer side of the valve plate, and a circle of exhaust through grooves in the inner side of the valve plate are arranged in the periphery of the exhaust hole. Two circles of through grooves are respectively arranged in the peripheries of the air intake and the exhaust hole at the two planes of the valve plate, on one hand, the contact area of an air intake valve piece and an exhaust valve piece is reduced, the impurity impact is reduced, and the sealing performance is improved, on the other hand, the through grooves can store fuel, and the sealing performance is improved when a fuel film is formed during the movement of the valve pieces. Consequently, the valve plate of the automobile air-conditioning compressor can enable the valve plate, the air intake valve piece and the exhaust valve piece to have better sealing performances, and can be suitable to batch production.
Description
Technical field
The utility model relates to a kind of inner body of air condition compressor, and the valve plate of a kind of sloping plate type vehicle air condition compressor of more specifically saying so belongs to automobile air conditioner compressor manufacturing technology field.
Background technique
Existing automobile air conditioner compressor adopts the sloping plate type vehicle air condition compressor mostly; It is to lean on valve plate and suction valve chip, exhaust valve plate to isolate the high low pressure chamber that the air-flow high low pressure of sloping plate type vehicle air condition compressor is set up; Suction valve chip and exhaust valve plate are close to respectively on two planes of valve plate, as two one-way valves.In the compressor operating breathing process, open suction valve chip and require exhaust valve plate and valve plate good seal simultaneously, do not have and leak, in the compressor air-discharging process, open exhaust valve plate and require suction valve chip and valve plate good seal simultaneously, do not have and leak.Therefore the valve plate sealing directly influences the quality and the working efficiency of compressor.
At present, the valve plate of sloping plate type vehicle air condition compressor comprises circular plate, on circular plate, is provided with suction port, exhaust port, and its production is directly die stamping moulding on circular plate, behind the burr of removal aperture two planes is ground.
Existing automobile air conditioner compressor has suction valve chip, the exhaust valve plate that cooperates with valve plate; The clack valve area of suction valve chip, exhaust valve plate is bigger than the aperture of valve plate suction port, exhaust port; The clack valve of valve block and valve plate surface of contact are bigger; There are impurity or the bad meeting of planeness influence sealability at suction port, exhaust port periphery, need reduce sealing area and improve sealability.As considering to reduce suction, exhaust valve plate clack valve area scheme,, the valve block orientation problem influences sealing effect partially owing to can causing sealing.
The model utility content
To above-mentioned situation, the problem that the utility model quasi-solution is determined provides a kind of valve plate of automobile air conditioner compressor, and it can make valve plate and suction valve chip, exhaust valve plate have better sealing, and can be fit to produce in batches.
For achieving the above object; The utility model has adopted following technological scheme: a kind of valve plate of automobile air conditioner compressor, and it comprises circular plate, said circular plate is provided with suction port, exhaust port; When setting said valve plate and installing; Said circular plate is that inboard, the opposite side of valve plate is the outside of valve plate towards a side of automobile air conditioner compressor piston, in the outside of valve plate, has a circle exhaust around the said exhaust port and passes through dead slot.
It is concentric with exhaust port that dead slot is passed through in said exhaust.In the inboard of valve plate, has the air-breathing dead slot of a circle around the said suction port.Said air-breathing dead slot is concentric with suction port.
Adopt said structure; The valve plate of the automobile air conditioner compressor of the utility model passes through dead slot because suction, exhaust port on valve plate two planes are provided with a circle on every side, has reduced the surface of contact with suction, exhaust valve plate on the one hand; Reduce the impurity effect degree and improve sealing; On the other hand, passing through dead slot can oil storage, forms oil film during valve plate movement and improves sealing.Therefore, the valve plate of the automobile air conditioner compressor of the utility model can make valve plate and suction valve chip, exhaust valve plate have better sealing, and can be fit to produce in batches.
Description of drawings
Fig. 1 is the structural representation in the valve plate outside of the utility model automobile air conditioner compressor;
Fig. 2 is the inboard structural representation of valve plate of automobile air conditioner compressor;
Fig. 3 is valve plate suction port, exhaust port sectional structure chart.
Among the figure: the 1-circular plate, the 2-exhaust port, the 3-suction port, dead slot is passed through in the 4-exhaust, the air-breathing dead slot of 5-.
Embodiment
Like Fig. 1, shown in Figure 3; The valve plate of the automobile air conditioner compressor of the utility model, it comprises circular plate 1, said circular plate 1 is provided with suction port 3, exhaust port 2; When setting said valve plate and installing; Said circular plate 1 is that inboard, the opposite side of valve plate is the outside of valve plate towards a side of automobile air conditioner compressor piston, it is characterized in that the outside at valve plate, has a circle exhaust around the said exhaust port 2 and passes through dead slot 4.It is concentric with exhaust port 2 that dead slot 4 is passed through in said exhaust.
Referring to Fig. 2, Fig. 3,, has the air-breathing dead slot 5 of a circle around the said suction port 3 in the inboard of valve plate.Said air-breathing dead slot 5 is concentric with suction port 3.
The degree of depth that dead slot 4, air-breathing dead slot 5 are passed through in said exhaust is 0.3 millimeter, and forming method is through the die stamping moulding, in the suction port 3 on punching press circular plate 1, the exhaust port 2, dead slot 4,5 impact briquettings of air-breathing dead slot is passed through in exhaust.
