Abstract
The utility model discloses a two-way cam plate type vehicle air conditioner compressor which is with the fixed displacement; the utility model includes a cylinder body whose front part and the rear part are connected; two ends of the cylinder body are connected with a cylinder cover; a valve plate and a valve leaf which are used to control the circulating and flowing direction of the cooling gas are provided between the cylinder body and the cylinder cover; a main shaft, a cam plate, a ball pad, a steel ball and a piston which makes the reciprocating straight line movement are provided inside the cylinder body; the main characteristics of the utility model is that 9 piston holes are provided on the cylinder body; each piston hole corresponds to a piston; 9 pistons form the cylinder chambers of 18 cylinders in two directions; 9 vent holes which are respectively used for air suction and air exhaust are also provided on the valve plate of the corresponding cylinder chamber; the improved structure makes the displacement and the cooling power of the compressor larger, thus satisfying the requirement of the large-sized vehicle air conditioning system; and the invention is with light weight and saves the energy consumption.
Description
Technical field
The utility model relates to a kind of two-way ramp type fixed displacement automobile air conditioner compressor, relates to a kind of two-way ramp type fixed displacement of 18 cylinders automobile air conditioner compressor that can assemble 9 pistons specifically.
Background technique
Automobile air conditioner compressor be installed on various big, main frame in the middle bus air-conditioning system, it mainly acts on is to be used for providing pressurized air for automobile, so that for automotive air-conditioning system provides power, its working procedure is: behind belt wheel input power, the swash plate that drives on main shaft and the main shaft by the magnetic clutch assembly rotates, because the outer rim shape of swash plate is a cylindrical inclined-plane that cuts that becomes the specific angle of cut with main shaft, can make reciprocal beat along with the rotation of main shaft, again through after the conduction that is assemblied in ball pad between two inclined-planes of swash plate and steel ball respectively, just can promote piston does reciprocating linear motion, the motion of piston cause with the piston two ends match before, cylinder chamber's volume in the rear-bank rotor housing changes, the variation of this volume is to change according to the cycle of motion of piston and frequency, the suction valve chip and the exhaust valve plate of control airflow direction are installed near cylinder chamber's endface position between cylinder body and cylinder cap, when compressor is in operation, cylinder chamber's volume-variation and the pressure difference that produces just makes valve block to open automatically or to close, the refrigerant gas in the refrigeration system just can circulate in an orderly manner.Though more than these automobile air conditioner compressors can satisfy the demand of some large and medium-sized passenger vehicles, but when being applied in large-scale refrigerator car, because the general-utility car air condition compressor at most only is equipped with 7 pistons usually, form the cylinder chamber of two-way 14 cylinders, often do not reach higher air displacement, caused the deficiency of refrigeration work consumption, and in order to reach higher air displacement, have only by increasing the volume of cylinder chamber, but when increasing cylinder chamber's volume, must cause the increase of compressor volume, the increase of weight, and consume more energy.
Summary of the invention
Goal of the invention of the present utility model provides in the defective that overcomes prior art all that a kind of volume is little, in light weight, saving energy, discharge capacity and the big two-way ramp type fixed displacement automobile air conditioner compressor of refrigeration work consumption.
Goal of the invention of the present utility model realizes by following technical proposal:
A kind of two-way ramp type fixed displacement automobile air conditioner compressor, before comprising, the interconnected cylinder body in back, the cylinder body two ends connect cylinder cap, be provided with valve plate and valve block between cylinder body and the cylinder cap, be provided with main shaft in the cylinder body, swash plate, the ball pad, steel ball and piston, this piston does reciprocating linear motion in the cylinder piston hole and two-way formation cylinder chamber, the main shaft overhanging end connects the belt wheel of input power, it is characterized in that described cylinder body is provided with 9 piston holes, the corresponding piston of each piston hole, 9 piston two-ways form the cylinder chamber of 18 cylinders, to should also being provided with air-breathing and each 9 vent of exhaust on the valve plate of cylinder chamber.
Compared with prior art, the utility model is to have additional 9 piston holes on the automobile air conditioner compressor cylinder body under the prerequisite that does not increase the compressor volume, the corresponding piston of each piston hole, 9 piston two-ways form the structure of the ramp type fixed displacement automobile air conditioner compressor of 18 cylinders, the compressor of this structure has bigger discharge capacity and refrigeration work consumption, its in light weight, saving energy.

Embodiment
To elaborate again to the utility model embodiment by above-mentioned accompanying drawing below.
As Fig. 1～shown in Figure 7, two-way ramp type fixed displacement automobile air conditioner compressor, before comprising, the interconnected cylinder body 4 in back, 10, the cylinder body two ends connect cylinder cap 3,13, be provided with the valve plate 11 and the valve block 12 of the mobile direction of control refrigerant gas between cylinder body and the cylinder cap, be provided with main shaft 2 in the cylinder body, swash plate 7, ball pad 8, steel ball 6 and piston 5, main shaft drives swash plate, and promote piston 5 by the conduction that is located at ball pad on the swash plate and steel ball and carry out linear reciprocating motion, this piston is arranged in the associated cylinder piston hole 14, its quantity is 9, and the cylinder chamber 9 of two-way formation 18 cylinders, and also be provided with air-breathing on the valve plate 11 near cylinder chamber's endface position and each 9 vent 15 of exhaust, for the circulation of refrigerant gas.
Power of the present utility model comes from the belt wheel 1 that main shaft 2 connects, under the drive of belt wheel, can promote piston set in the cylinder body 5 and carry out linear reciprocating motion, because the quantity of piston is added to 9, and the cylinder chamber 9 of two-way formation 18 cylinders, therefore have bigger discharge capacity and refrigeration work consumption, can be applicable in the air-conditioning system of large-scale passenger vehicle, lorry, refrigerator car and other High-Powered Vehicles.
