Abstract
When double oily separate type air conditioning compressor for displacement variable car work, the lubricating oil that crankcase refrigerant gas can carry the splashing of main shaft (39) center flows to suction muffler by spindle hole, oil is separated with refrigerant gas by tower spring (25), separated oil flows to lower end under gravity, crankcase is flowed back to by oil return valve (43), the refrigerant gas of the lubricating oil containing very small amount enters suction muffler, it is discharged into air-conditioning system, realizes maximized refrigerating capacity.When car room temperature reaches requirement; double oily separate type air conditioning compressor for displacement variable car can automatically become small displacement compressors; lubricating oil in discharge chamber would generally rest on the foot of compressor; lubricating oil is by being arranged on the drainback passage and control valve of compressor bottom; it is brought back into the crankcase of compressor; the content of lubricating oil in air-conditioning system is reduced, the high energy efficiency of air-conditioning system is realized.
Description
Technical field
The utility model is mainly used in air conditioning for automobiles, a kind of double oily separate type air conditioning compressor for displacement variable car.
Background technology
To save emission reduction, oil consumption is reduced, domestic automobile production firm proposes to grind in succession to automobile air conditioner compressor factory
Send out and apply high-effect air conditioning compressor for displacement variable car.Such double oily separate type air conditioning compressor for displacement variable car are suitable
Develop in response to the market demand.
The purpose of this utility model is to reduce the cycling rate of air-conditioning system oil, has two kinds of architectural features to meet this requirement：
1st, compressor inner structure must have certain structure for preventing lubricating oil from discharging compressor crankcase.
2nd, the lubricating oil in air-conditioning system must have the structure for flowing back to compressor crankcase.
The content of the invention
Double oily separate type air conditioning compressor for displacement variable car, mainly by driving disc assembly (3), belt wheel assembly (5), line
Circle assembly (7), protecgulum (38), push-plate (36), swash plate body (35), sliding plate (34), axle sleeve (32), main shaft (39), tower spring (25), the
One has strong market potential (28), and second has strong market potential (37), cylinder body (27), gasket seal (31) before cylinder body, piston (22), valve plate (17), sealing gasket
Piece (19), bonnet (21), control valve (40), oil return valve (43) composition, it is characterised in that main shaft (39) center deep hole and tower spring
(25) constitute double oil eliminators, cylinder body, valve plate and after the oil return through-hole that covers constitute filling passage, it is when the compressor is operated, bent
The lubricating oil that axle box refrigerant gas can carry the splashing of main shaft (39) center flows to suction muffler by spindle hole, passes through tower spring
(25) oil is separated with refrigerant gas, separated lubricating oil flows to lower end under gravity, passes through oil return valve (43)
Crankcase is flowed back to, the refrigerant gas of the lubricating oil containing very small amount enters suction muffler, is discharged into air-conditioning system.
When car room temperature reaches requirement, double oily separate type air conditioning compressor for displacement variable car can automatically become small displacement pressure
Lubricating oil in contracting machine, discharge chamber would generally rest on the foot of compressor, and lubricating oil is by being arranged on compressor bottom
Drainback passage and control valve (40), be brought back into the crankcase of compressor, reduce the content of lubricating oil in air-conditioning system.

Embodiment
In Fig. 1, the first roughing external diameter of main shaft (39), the deep hole of depth drill machining spindle (39), this deep hole is oil
From the part of device, cross-drilled hole at processing radial direction two is bored, spline, Quenching Treatment, fine cylindrical is squeezed.Cylinder body (27) Vehicle Processing end face, boring
Cylinder holes, drilling includes oil return through-hole at two.The manufacture of tower spring (25) belongs to ripe rolling technology.At valve plate (17) punch process two
Oil return through-hole.Bonnet (21) processes plane, processes screw thread, and machining control valve opening processes suction and exhaust ports, processes oil return through-hole.Modeling
Expect that the cost of oil return valve (43) mold developing of material is low, easily realize.Push-plate (36) and swash plate body (35) cast hair first
Base, modifier treatment, then push-plate blank, which is delivered, carries out lathe, the processing of machining center machinery between machine extra bus and cleans, and turns hot extra bus
Between light decorations process.During assembling is constituted, axle sleeve (32) is connected with swash plate body (35), hand assembled, push-plate (36) and swash plate body (35)
Connected by hinge (29).Remaining parts is that existing normal process is assembled.
In fig. 2, forward thrust bearing (11) is placed between forward thrust pad (10) and back pressure pad (12).
In figure 3, suction valve chip (16) coordinates with cylinder body (27), and gasket seal (19) coordinates with bonnet (21), valve plate
