Cylinder body 100 replaces the cylinder body 70 of conventional reciprocating formula compressor shown in Figure 1, and it comprises compression chamber 101, and the piston 50 (referring to Fig. 1) that links to each other with connecting rod 40 (referring to Fig. 1) does reciprocating linear motion therein.Cylinder body 100 links to each other with body frame 24 by first, second screw 103,104.Compression chamber 101 forms sealing with the cylinder head 60 (referring to Fig. 1) with refrigerant discharge chamber 62 (referring to Fig. 1).Compression chamber 101 is become one with cylinder body 100.Valve member 80 (referring to Fig. 1) is between cylinder body 100 and cylinder head 60.
First, second vent silencer 110,120 (referring to Fig. 4) is positioned at the relative both sides of cylinder body 100.First vent silencer 110 links to each other with the refrigerant discharge chamber 62 of cylinder head 60 by the coolant channel 102 that is formed in the cylinder body 100.Second vent silencer 120 links to each other with first vent silencer 110, and the refrigerant discharge 140 that links to each other with condenser simultaneously is also coupled.In addition, first, second vent silencer 110,120 has predetermined volume to reduce the resonance that flow of refrigerant is produced.Vent silencer 110,120 preferred heights between 14mm to 30mm and its volume preferably at 15cc between the 25cc.
In addition, the first baffler end cap 111 with through hole 112 links to each other with the upper end open of first vent silencer 110, is formed with tapped hole 113 in the bottom of first vent silencer 110 simultaneously.Similarly, the second baffler end cap 121 with through hole 122 links to each other with the upper end open of second vent silencer 120, is formed with tapped hole 123 in the bottom of second vent silencer 120 simultaneously.One end of refrigerant discharge 140 passes the second baffler end cap 121 and is inserted in second vent silencer 120.
Simultaneously, first screw 103 passes the first baffler end cap 111 via through hole 112, and is fastened on the body frame 24 when it is assembled in the tapped hole 113 of first vent silencer 110.Second screw 104 passes the second baffler end cap 121 via through hole 122, and is fastened on the body frame 24 when it is assembled in the tapped hole 123 of second vent silencer 120.Like this, first, second vent silencer 110,120 forms sealing by first, second baffler end cap 111,121 respectively, and cylinder body 100 links to each other with body frame 24 simultaneously.
Connecting passage 130 passes cylinder body 100 so that first vent silencer 110 is connected to second vent silencer 120.Connecting passage 130 is in the shape of the letter V to reduce the exhaust pulse of refrigerant.In addition, connecting passage 130 adopts neck shaped to reduce exhaust pulse more effectively, specifically, is arranged to make passage at least a portion to have less diameter.
The internal diameter size of connecting passage 130 is determined according to the situation that exhaust pulse produces.When the internal diameter size of connecting passage 130 was big, connecting passage 130 efficient that are used to reduce exhaust pulse reduced, and when its size too hour, then because the flow resistance of refrigerant increases, the compression efficiency of compressor reduces.Correspondingly, the diameter of connecting passage 130 should be defined as a suitable value, and its preferred size is between 1.5mm to 4.0mm.
Discharge process to compression refrigerant in the reciprocal compressor that has said structure among the present invention describes below.
When piston 50 when in compression chamber 101, moving back under the rotary action of bent axle 23 to bottom dead center, the refrigerant suction chamber 61 of low-pressure refrigerant by cylinder head 60 that flow in the absorbing silencer 90 (referring to Fig. 1) by suction pipe 91 (referring to Fig. 1) flow in the compression chamber 101.After this, when piston 50 was shifted to top dead along with the further rotation of bent axle 23 in compression chamber 101, refrigerant was compressed and forms high pressure.
Compressed refrigerant temporarily is stored in the refrigerant discharge chamber 62 of cylinder head 60, and then the coolant channel 102 by cylinder body 100 flows to first vent silencer 110.Refrigerant in first vent silencer 110 then flows to second vent silencer 120 by connecting passage 130, flows to the condenser (not shown) by refrigerant discharge 140 then.
In the discharge process of refrigerant, because the refrigerant of compression flows in first vent silencer 110 with preliminary dimension and volume by the refrigerant discharge chamber 62 of cylinder head 60, then the connecting passage 130 by the V font flow into second vent silencer 120 from first vent silencer 110, so the exhaust pulse of refrigerant reduces.
In addition, owing to form V-shape, pass cylinder interior from first vent silencer row to the connecting passage of the passage of second vent silencer as refrigerant, the reciprocal compressor among the present invention has the effect of the vibration that suppresses the compressor that flow of refrigerant causes.
In addition, because body frame and the separating component of cylinder body for linking to each other by screw, rather than one-piece element, the vibration that produces in the cylinder body is difficult for being delivered on the body frame like this, and the reciprocal compressor among the present invention can reduce the body vibration of compressor effectively.
In addition, in the present invention, easily assemble because body frame and cylinder body are independently made also as the parts with simple structure, thereby can reduce manufacture cost.
