- the link pin 161 connecting the link arm 160 and the swash plate arm 120 or the rotor arm 110 receives an unbalanced compression reaction force, and thus a problem is easily broken and worn.
- the coupling center line (Y) of the rotor arm 110 and the swash plate arm 120 is a swash plate ( 91) and the piston 70 may be located at a position where the shoe 62 is interlocked.
- the position of the rotor arm 110 on the rotor 93 and the position of the swash plate arm 120 on the swash plate 91 are spaced apart from the center line Y of the shaft 94 to the rotational direction side of the shaft 94, respectively.
- the compression reaction force P acting from the piston 70 to the swash plate 91 may be located within a range. Strictly, it may be most preferable to coincide with the action line P1 where the compression reaction force P is generated.
- the compression reaction force P is stably supported by the swash plate arm 120 and the rotor arm 110 and the link arm 160 and the link pin 161 disposed on the same line or parallel line. do.
- FIG. 9 shows an exploded perspective view of the present invention.
- a rotor 93 is mounted on a part of the outer circumferential surface of the shaft 94, and a pair of rotor arms 110 are disposed on the rotor 93.
- the swash plate arm 120 includes the first and second swash plate arms 130 and 140 as described above. As described above, on the first swash plate arm 130, the heat treatment unit 150 or the area increase unit 135 may be processed.
- first and second swash plate arms 130 and 140 and the rotor arm 110 are connected by a link arm 160 and a link pin 161.
- the first return spring 95 is inserted along the axial direction of the shaft 94, and the shaft 94 is disposed through a through portion formed at the central side of the swash plate arm 120.
- the first return spring 95 exerts an elastic force in a direction to minimize the inclination angle of the swash plate 91 at one side of the swash plate 91.
- the bush 96 is placed in contact with the end of the first return spring 95, the shaft 94 is inserted into the hollow hole of the bush 96, and the bush 96 is a shaft ( 94).
- the swash plate arm 120 is located on the outer circumferential surface of the bush 96.
- a retainer 99 is coupled to the other side of the shaft 94, and a second return spring 98 is disposed between the bush 96 and the retainer 99.
- the second return spring 98 also exerts an elastic force in a direction to minimize the inclination angle of the swash plate 91 from the other side of the swash plate 91. That is, the first and second return springs 95 and 98 are disposed on both sides of the swash plate 91, respectively, and exhibit elastic force in a direction in which the inclination angle of the swash plate 91 is minimized.
- the present invention relates to a swash plate type compressor and has industrial applicability.
