Description
Technical field
The utility model relates to automobile air conditioner compressor, is specifically related to a kind of variable displacement swash plate compressor.
Background technique
In the refrigeration system of car air conditioner, variable displacement swash plate compressor in the course of the work, controls the change of discharge capacity by the change of swash plate angle.Therefore, variable displacement swash plate compressor changes the pressure of air-conditioning refrigeration system in the course of the work, the resistance of gas flow and direction controlling require very high, the bad meeting controlled causes the pulsation of air-flow, thus noise when can affect compressor operating and vibration etc.
As shown in Figure 1 and Figure 2, the air aspiration cavity of traditional variable displacement swash plate compressor cylinder body 1 is square air aspiration cavity 1-1, and the resistance of compressor gas flow is in the course of the work comparatively large, and the wasted work that can increase compressor reduces its efficiency.And gas being subject to resistance rear to changing, causing the noise of compressor and vibration to strengthen, thus affecting its comfort level and life-span.In addition, suction, the exhaust cavity of bonnet 7 are separated by quincuncial separation profile 7-1, cause the length sealed, add the risk of leakage.Quincuncial separation profile 7-1 determines spacing plate of discharge valve block and also can only adopt Structural Hardware, and during compressor operating, metal covering pats the noise adding compressor on metal covering, reduces the life-span of compressor.
Model utility content
For solving the problem, the purpose of this utility model is to provide a kind of variable displacement swash plate compressor, reach noise low, vibrate little, efficiency is high, the object of long service life.
The technical solution of the utility model is: a kind of variable displacement swash plate compressor, comprise cylinder body to be linked together by valve plate assembly and bonnet, the centre of described bonnet is provided with air aspiration cavity, exhaust cavity, circular point muscle is provided with in the middle of described air aspiration cavity, exhaust cavity, the centre of described exhaust cavity is provided with silencing cavity, and described circle is divided between muscle and silencing cavity and is provided with one-way valve; The intakeport bottom end of described cylinder body is the reducing drag be obliquely installed.
Further, the upper and lower side of the entry end of the intakeport of described cylinder body is arranged with the convex tendon for noise reduction.
Further, described valve plate assembly is tightly connected successively is formed by cylinder body seal pad, suction valve chip, valve plate, exhaust valve plate, exhaust sealing pad; The suction port side described valve plate being positioned at suction face is provided with air-breathing dashpot, and the exhaust port side being positioned at its deflation area is provided with exhaust dashpot.
Further, described exhaust valve plate is the narrow blade profile shape of the wide root of head, the both sides of described exhaust valve plate are respectively provided with a positioning hole for being fixedly connected with valve plate, and the root of exhaust valve plate offers the long-round-shape vent for connecting valve plate and bonnet pore.
The intermediate cavity of described exhaust sealing pad is provided with limiting board; Limiting board and exhaust sealing pad are integrated, and the profile of the vent on exhaust sealing pad is long-round-shape.
Variable displacement swash plate compressor cylinder body of the present utility model is linked together by valve plate assembly and bonnet, valve plate assembly is by cylinder body seal pad, suction valve chip, valve plate, exhaust valve plate, exhaust sealing pad is tightly connected composition successively, namely the one side of cylinder body is fitted with cylinder body seal pad, the another side of cylinder body seal pad and suction valve chip are fitted, the another side of suction valve chip and valve plate are fitted, the another side of valve plate and exhaust valve plate are fitted, another side and the rear sealing cushion for cover of exhaust valve plate are fitted, the another side of rear sealing cushion for cover and bonnet seal fits, form a sealingly secure overall reliably.
Skewed reducing drag is provided with at the bottom end of the intakeport of cylinder body, gas makes the air-flow of different direction reach unanimity through this reducing drag when entering intakeport, leads, reduce the resistance of air-flow to air-flow with direction, thus reduce power consumption, improve the efficiency of compressor.In addition, symmetrically arranged two convex tendons of intakeport upper and lower, for air-flow provides two-stage noise reduction, reduce the pulsation of air-flow, thus reduce the noise of compressor.
The blade that during work, suction valve chip is corresponding is opened, and the blade that exhaust valve plate is corresponding is closed, compressor starts air-breathing.And when the blade that suction valve chip is corresponding is closed, the blade that exhaust valve plate is corresponding is opened, then compressor starts exhaust.The blade of suction valve chip and the blade cyclic of exhaust valve plate open closedown, realize the conversion of air-breathing, exhaust.Valve plate plays the effect providing support face to suction valve chip, exhaust valve plate.Due to piston air-breathing complete proceed to exhaust time, suction valve chip also proceeds to closedown by opening, due to the impact of air-flow in closing process, noise is inevitably had to produce, so be provided with air-breathing dashpot in the suction port side of the suction face of valve plate, the reaction force of air-flow provides cushion effect to reduce its noise to valve block when closing.Equally, also like this during exhaust valve plate work, so be provided with exhaust dashpot at the exhaust port of the deflation area of valve plate, improve the life-span of suction valve chip, exhaust valve plate.
Because the restriction of cylinder body upper cylinder half hole site, so the vent on cylinder body is also fixing, and the vent of bonnet is limited by control valve opening, causes cylinder body different with the pore position of bonnet.Because the ventilation position of exhaust valve plate is designed to long-round-shape, can easily the valve plate hole of position not in same point and back cover hole be coupled together.
They are separated by a circular point muscle by the air aspiration cavity of bonnet and exhaust cavity, substantially reduce the effective length of sealing, make sealing more firm; In addition, the profile of point muscle because being rule, processing is simpler, also reduces cost.In addition, silencing cavity and one-way valve are set in the exhaust cavity of bonnet, make high pressure draught inside bonnet, outside, silencing cavity can play the effect of noise reduction; All through one-way valve, the flowing of gas to be made so more stable, and refluence phenomenon can not be caused before air-flow flows out bonnet simultaneously.
