-
FIG. 3 is a sectional view of an example of an inside structure of acompressor 100 according to an embodiment of the present invention;FIG. 4 is a partial perspective view of the compressor being dissembled. - As illustrated in
FIG. 3 , thecompressor 100 has abody 10 comprising afront cylinder 11 and arear cylinder 30. Inside thebody 10, afront discharge chamber 21 is formed at a front side (the left side relative toFIG. 3 ) of aswash plate 20 to be positioned, and arear discharge chamber 23 is formed in arear housing 70 connected to therear cylinder 30 at a rear side (the right side relative toFIG. 3 ) of theswash plate 20. - The
rear housing 70 includes anintake port 17 for introducing a refrigerant into thebody 10, and adischarge port 19 for discharging the refrigerant compressed in the body. - The
front discharge chamber 21 and therear discharge chamber 23 temporarily store the compressed refrigerant in the front and rear regions inside thebody 10. A desirable structure for discharging the compressed refrigerant of the front andrear discharge chambers - For the above desirable structure, a
muffler space 29 and a connectingpath 25 are formed inside the body 10 (at an upper part relative toFIG. 3 ). Themuffler space 29 is to reduce the pulsation of the compressed refrigerant. The connectingpath 25 connects through themuffler space 29, thefront discharge chamber 21 and therear discharge chamber 23, to lead the refrigerant of the front andrear discharge chambers muffler space 29. - Since the gist of the present invention is to allow the refrigerant of the
rear discharge chamber 23 to be moved into themuffler space 29 and thereafter to be discharged, therear discharge chamber 23 should not be directly connected to thedischarge port 19. - Further, a
discharge path 27 is formed inside thebody 10. Thedischarge path 27 connects through themuffler space 29 and thedischarge port 19. Therefore, the refrigerant from themuffler space 29 is led to thedischarge port 19 and is discharged through thedischarge port 19. - As illustrated in
FIG. 4 , in the structure with thedischarge path 27 and the connectingpath 25, the connectingpath 25 is formed by connectingapertures rear cylinder 30, agasket 40 and a valve plate 50 and which are continuously aligned. - Further, the
discharge path 27 is formed bydischarge apertures rear cylinder 30, thegasket 40 and the valve plate 50 and which are continuously aligned. The discharge apertures 37, 47 and 57 formed the components are formed atprotrusions discharge path 27 upon manufacturing. - Reference numeral “60” indicates a gasket head which includes a
protrusion 65 and adischarge aperture 67 formed on theprotrusion 65, to form thedischarge path 27, together with the other components. - In accordance with the above-described structure, the refrigerant is compressed inside the
body 10 and moved into each of thefront discharge chamber 21 and therear discharge chamber 23. Then all the refrigerant is moved to themuffler space 29 through the connectingpath 25, and thereafter, the pulsation of the refrigerant is sufficiently reduced in themuffler space 29, and the refrigerant is discharged through thedischarge port 19. - Consequently, in the structure for discharging the refrigerant in the compressor according to the embodiment of the present invention, all refrigerant compressed inside the
body 10 is discharged after passing through themuffler space 29. - The structure in which the discharge path is formed outside the body will be described below:
- In a bi-directional swash
plate type compressor 100, a refrigerant is compressed in abody 10 with afront cylinder 11 and arear cylinder 30, and the compressed refrigerant is temporarily stored in each of afront discharge chamber 21 and arear discharge chamber 23. Thefront discharge chamber 21 is formed in a front side in thebody 10, and therear discharge chamber 23 is formed in a rear side in thebody 10 and is specifically formed in arear housing 70 connected to therear cylinder 30. Thereafter, the compressed refrigerant temporarily stored in each of thefront discharge chamber 21 and therear discharge chamber 23 jointly flows to be discharged through adischarge port 19 formed in therear housing 70. When the refrigerant discharged from therear discharge chamber 21 is mixed with the refrigerant discharged from therear housing 70 in amuffler space 29 formed at an upper part of the body, a pulsation of the refrigerant is offset. Further, while the refrigerant passes through adischarge path 27 which connects themuffler space 29 and thedischarge port 19 and which is formed outside the body, the pulsation of the refrigerant is reduced. - Further, a bi-directional swash
plate type compressor 100, a refrigerant is compressed in abody 10 with afront cylinder 11 and arear cylinder 30, and the compressed refrigerant is temporarily stored in each of afront discharge chamber 21 and arear discharge chamber 23. Thefront discharge chamber 21 is formed in a front side in thebody 10, and therear discharge chamber 23 is formed in a rear side in thebody 10 and is specifically formed in arear housing 70 connected to therear cylinder 30. Thereafter, the compressed refrigerant temporarily stored in each of thefront discharge chamber 21 and therear discharge chamber 23 jointly flows to be discharged through adischarge port 19 formed in therear housing 70. Wherein, the bi-directional swashplate type compressor 100 comprises: a connectingpath 25 and adischarge path 27 inside thebody 10. The connectingpath 25 connects through themuffler space 29, thefront discharge chamber 21 and therear discharge chamber 23, to lead the refrigerant of thefront discharge chamber 21 and therear discharge chamber 23 into themuffler space 29 formed at an upper part of thebody 10. Thedischarge chamber 27 is connected to thedischarge port 19 and themuffler space 29 and is formed outside the body. Thedischarge path 27 allows the refrigerant to flow from themuffler space 29 and to be led to thedischarge port 19 through which the refrigerant is discharged. Therefore, the refrigerant of thefront discharge chamber 21 and therear discharge chamber 23 is discharged after joining in themuffler space 29. - Then, the
discharge path 27 is directly connected to thedischarge port 19. - Further, the
discharge path 27 is connected to thebody 10, at a position spaced apart from thedischarge port 19 at a predetermined interval. Aflow path 80 is formed between thedischarge path 27 and thedischarge port 19 inside thebody 10. - That is, the refrigerant discharged from the
front discharge chamber 21 is mixed with the refrigerant discharged from therear housing 70 in themuffler space 29 formed at the upper part in thebody 10, so that the pulsation of the refrigerant is offset. Further, the refrigerant passes through thedischarge path 27 which connects themuffler space 29 and thedischarge port 19 and which is formed outside the body, so that the refrigerant is discharged through thedischarge port 19 after the pulsation of the refrigerant is reduced. - Then, the
discharge path 27 may be selected, in use, from a pipe shape, an O-ring shape, or a stopper shape. - As described above, in accordance with the inside and outside structures for discharging a refrigerant in a bi-directional swash plate type compressor, since all refrigerant compressed in the front region and the rear region inside the compressor is moved into the muffler space and thereafter is discharged irrespective of the position of the
