Description
- The present invention relates to an arrangement that introduces compressed fluid from a discharge chamber to a crank chamber in a variable-displacement swash plate compressor designed to change the inclination angle of the swash plate by controlling the pressure in the crank chamber.
- Japanese Patent Publication (JP-B) No. 32479/1990 discloses an arrangement that introduces compressed fluid from a discharge chamber to a crank chamber in a conventional variable-displacement swash plate compressor.
- The variable-displacement swash plate compressor disclosed is outlined below.
- As shown in Figs. 1 and 2, a compressor housing 1 with a cylindrical casing 11, one end of which is closed by a
front end plate 12, defines a crank chamber 2 and has acylinder block 3 inside. Acylinder head 14 is installed through avalve plate 13 on thecylinder block 3 to define asuction chamber 15 and adischarge chamber 16 between thecylinder head 14 and thevalve plate 13. - A main rotating
shaft 4, passing through the center of the crank chamber 2, mentioned above, is rotatably borne throughneedle bearings front end plate 12 and thecylinder block 13, respectively. - A
pin 51 secures arotor 5 to the main rotatingshaft 4, extending through the crank chamber 2. Abracket 53 with apin 52 is formed on therotor 5, and thepin 52 is slidably fit into aslot 62, formed in anarm 61 extending from aswash plate 6. - A wobble plate 7, fit over a
bearing unit 63 formed in theswash plate 6, is disposed over theswash plate 6, with abearing 65 between the wobble and swash plates, so that arotation prevention mechanism 64 prevents the wobble plate from rotating. - Pivots 71 of
piston rods 33, described later, and apin 72, fitting into therotation prevention mechanism 64, are provided at the external edge of the wobble plate 7. A plurality ofcylinder bores 31 and acommunication path 9, all of which are substantially parallel with the main rotatingshaft 4, and a displacement control mechanism 8 are formed in thecylinder block 3. Pistons 32 are disposed in thecylinder bores 31, each of the pistons being connected through apiston rod 33 to the wobble plate 7. Thus when an external drive source rotates the main rotatingshaft 4 via apulley 100 and aclutch 101, therotor 5 andswash plate 6 also rotate together with the main rotatingshaft 4. However, the wobble plate 7 only wobbles because therotation prevention mechanism 64 prevents the wobble plate's rotation. Wobbling motion of the wobble plate 7 causes thepistons 32 to slide back and forth in thecylinder bores 31 by the aid of thepiston rods 33. - Using reciprocation of the
pistons 32, fluid is taken into thecylinder bores 31 throughsuction holes 34, communicating with thesuction chamber 15, and check valves (not shown) are operated to discharge compressed fluid throughdischarge holes 35 into thedischarge chamber 16. - The displacement control mechanism 8 has a
valve 81 and a bellows 82, both of which are disposed inside a casing 83 in a chamber 36, provided next to the bearing unit for the main rotatingshaft 4 in thecylinder block 3. The casing 83 is provided with communication holes 84 and 85. The communication hole 84 communicates with the crank chamber 2, and the communication hole 85 communicates via apath 86 with thesuction chamber 15. - If the pressure in the crank chamber 2 is above a predetermined value, the crank chamber 2 and
suction chamber 15 are made communicate with each other using the displacement control mechanism 8 to reduce the pressure in the crank chamber so that the compressor operates at its maximum compression displacement. If the pressure in the crank chamber is below the predetermined value, the communication of the crank chamber 2 with thesuction chamber 15 is shut off, thus causing the inclination angle of theswash plate 6 to vary with the pressure in the crank chamber 2, so that the compression displacement changes. - The
communication path 9 is formed in thecylinder block 3, thevalve plate 13, and avalve retainer 39, which path connects the crank chamber 2 with thedischarge chamber 16 so that the two chambers communicate with each other, and acapillary tube 91 is inserted into thecommunication path 9. Afilter 92 is attached to thedischarge chamber 16 side end of thecapillary tube 91. - Thus after being reduced in pressure by the
capillary tube 91, compressed fluid in thedischarge chamber 16 flows into the crank chamber 2 and changes the pressure in the crank chamber 2 using the displacement control mechanism 8, thereby varying the inclination angle of theswash plate 6 to control displacement. - The inner diameter and length of the
capillary tube 91 can be adjusted to set the pressure and rate of flow from thedischarge chamber 16 into the crank chamber 2 for appropriate values. - Although the crank chamber and the discharge chamber of the conventional variable-displacement swash plate compressor, described above, are arranged to communicate with each other, the communication path is formed between one of the cylinder bores and the other cylinder bores in the cylinder block.
- If the communication path is formed in such a manner, the thickness of a wall around the communication path is insufficient to provide a seal between a high pressure side (the discharge chamber) and a low pressure side (the suction chamber), causing a deterioration in compression performance or controllability. Insufficient wall thickness also causes a cylinder bore to deform.
- The EP-A-318 976 discloses a variable-displacement swash plate compressor according to the preamble of claim 1.
- It is an object of the present invention to provide a variable-displacement swash plate compressor that enables compression performance and controllability to be improved by providing a secure seal between a discharge chamber and a suction chamber in a cylinder head.
- It is another object of the present invention to provide a variable-displacement swash plate compressor that enables durability to be enhanced by preventing cylinder bore deformation.
- The object is solved by the variable-displacement swash plate compressor of
claim 1 or 4. - Further developments of the invention are given in the dependent claims.
- Fig. 1 is a cross-sectional view of a conventional variable-displacement swash plate compressor.
- Fig. 2 is a front view of part of a cylinder block of a conventional variable-displacement swash plate compressor.
- Fig. 3 is a cross-sectional view of an embodiment of the present invention.
- Fig. 4 is a front view of main part of a cylinder block of an embodiment of the present invention.
- Referring now to Figs. 3 and 4, an embodiment of the present invention is described below.
- As shown in Figs. 3 and 4, a compressor housing 1 with a cylindrical casing 11, one end of which is closed by a
front end plate 12, defines a crank chamber 2 and has acylinder block 3 inside. Acylinder head 14 is installed on thecylinder block 3 through avalve plate 13 to define asuction chamber 15 and adischarge chamber 16 between thecylinder head 14 and thevalve plate 13. - A main rotating
shaft 4, passing through the center of the crank chamber 2, mentioned above, is rotatably borne throughneedle bearings front end plate 12 and thecylinder block 3, respectively. - A
rotor 5 is secured to the main rotatingshaft 4, extending trough the crank chamber 2. Abracket 53 with apin 52 is formed on therotor 5, and thepin 52 is slidably fit into aslot 62, formed in anarm 61 extending from aswash plate 6. - A plurality of
cylinder bores 31 and acommunication path 9, all of which are substantially parallel with the main rotatingshaft 4, and a displacement control mechanism 8 are formed in thecylinder block 3. Pistons 32 are disposed in thecylinder bores 31. Thus when an external drive source rotates the main rotatingshaft 4, therotor 5 and theswash plate 6 also rotate together with the main rotatingshaft 4. Rotation of theswash plate 6 causes thepistons 32 to slide back and forth in thecylinder bores 31 by the aid ofshoes 66. - Using reciprocation of the
pistons 32, fluid is taken into thecylinder bores 31 throughsuction holes 34, communicating with thesuction chamber 15, and check valves (not shown) are operated to discharge compressed fluid throughdischarge holes 35 into thedischarge chamber 16. - The displacement control mechanism 8 of the embodiment is the case with a conventional variable-displacement swash plate compressor.
- A
silencer chamber 43, which is of expansion form and has muffler function, is installed on thecylinder block 3. Thesilencer chamber 43 attenuates pulsation of compressed fluid discharged which flows from thedischarge chamber 16 to thesilencer chamber 43 through acommunication path 10 and thecommunication path 9. Thesilencer chamber 43 is provided with adischarge hole 44 to allow compressed fluid to flow into a refrigerating circuit. - The
communication path 9 and thecommunication path 10, making the crank chamber 2 communicate with thedischarge chamber 16 of thecylinder head 14, are installed in thecylinder block 3, thevalve plate 13, and thecylinder head 14. Thecommunication path 9 is installed between thesilencer chamber 43 and thecylinder bores 31. A pipe-shaped orifice 45 is inserted into thecommunication path 9 on the crank chamber 2 side. Theorifice 45 can also be directly formed in thecylinder block 45. Afilter 46 is installed on thedischarge chamber 16 side of theorifice 45 to remove dirt from compressed fluid. - The
orifice 45 allows a predetermined amount of compressed fluid to flow from thedischarge chamber 16 to the crank chamber 2. The flow rate is adjusted by choosing one among a plurality of orifices having different hole diameters or lengths. - The embodiment of the present invention, described above, is a variable-displacement swash plate compressor having no wobble plate, but the present invention can of course apply to a variable-displacement swash plate compressor with a wobble plate.
