Abstract

용량가변형 경사판식압축기에 있어서 토출용량의 제어성의 향상등을 꾀함과 동시에, 압축기의 몸체를 보다 축소할 수 있게 한다.In the variable displacement inclined plate compressor, the controllability of the discharge capacity is improved, and the body of the compressor can be further reduced.

한상의 힌지기구(K),(K)를 회전지지체(10)에 뒤쪽으로 돌출되어 설치되 있는 지지아암(18A),(18B)와 지지아암(18A),(18B)의 파지부(18a),(18b)에 그 상단이 전후방향으로 회전가능하게 파지되며, 그 하단이 경사판측에 설치된 가이드구멍(a),(22b)에 미끄럼 가능하게 삽입관통된 가이프핀(22A),(22B)로 구성되며 또한 파지부(18a),(18b)가 경사판(14)의 상사점위치(T)를 사이에 두고 좌우대치이 되도록 설치된다.Gripping portions 18a of the support arms 18A, 18B and the support arms 18A, 18B on which the hinge mechanisms K and K of the upper phase protrude backward from the rotary support 10. The guide pins 22A and 22B which are slidably inserted into the guide holes (a) and (22b) on the inclined plate side and the upper end thereof are rotatably held in the front and rear directions at (18b). In addition, the holding portions 18a, 18b are installed so as to be left-right confrontation with the top dead center position T of the inclined plate 14 therebetween.

축방향의 투영면내에 거의 장방형을 이루는 파지부(18a),(18b)가 구동축(6)의 축심으로 부터 파지부(18a),(18b)를 통해서 원호를 따르도록 경사진다.The holding portions 18a and 18b which are almost rectangular in the projection plane in the axial direction are inclined from the axis center of the drive shaft 6 to follow the arc through the holding portions 18a and 18b.
