Title (EN) LEVEL SWITCH
(FR) CONTACTEUR DE NIVEAU
(KO) 레벨스위치
Abstract:
(EN) The present invention relates to a level switch in which: an output shaft of a driving body rotatably passes through and is thereby mounted to an upper end wall section of a chamber for receiving and storing liquid or solid contents; in a state in which the output shaft rotatably passes through and is thereby mounted to the upper end wall section of the chamber, a sleeve rotatably circumscribes the output shaft, with a spring interposed therebetween; a blade part contacting and compressing the contents that are in the vicinity of the sleeve and accumulate in the chamber is provided on the outer circumferential surface of a tip of the sleeve; and a relative rotation detection part is provided, which detects the occurrence of relative rotation between the sleeve and the output shaft that occurs when a load greater than the elastic force of the spring is transmitted to the blade part.
(FR) La présente invention concerne un contacteur de niveau dans lequel : un arbre de sortie d'un corps d'entraînement passe de manière rotative à travers une section de paroi d'extrémité supérieure d'une chambre et est ainsi monté sur celle-ci pour recevoir et stocker un contenu liquide ou solide; dans un état dans lequel l'arbre de sortie passe de manière rotative à travers la section de paroi d'extrémité supérieure de la chambre et est ainsi monté sur celle-ci, un manchon circonscrit de manière rotative l'arbre de sortie, un ressort étant interposé entre ceux-ci; une partie de lame entrant en contact avec le contenu qui est à proximité du manchon et s'accumule dans la chambre et comprimant celui-ci est disposée sur la surface circonférentielle externe d'une pointe du manchon; et une partie de détection de rotation relative détecte l'apparition d'une rotation relative entre le manchon et l'arbre de sortie qui se produit lorsqu'une charge supérieure à la force élastique du ressort est transmise à la partie de lame.
(KO) 본 발명은, 액체나 고체인 내용물을 받아서 이를 저장하는 챔버의 상단 벽부에 구동체의 출력축이 회전가능하게 관통되어 장착되게 하고, 상기 챔버의 상단 벽부에 회전 가능하게 관통되어 장착된 상태에서 상기 출력축에 스프링을 개재하여 상기 출력축에 슬리브가 회전 가능하게 외접되게 하고, 상기 슬리브의 선단의 외주면에 챔버에 쌓이는 슬리브의 주변의 내용물과 접촉하면서 압축하는 날개부가 마련되게 하고, 상기 스프링의 탄성력보다 큰 부하가 상기 날개부에 전달되어 상기 슬리브와 상기 출력축 간에 상대회전이 발생하는 것을 감지하는 상대회전감지부가 마련되어 있는 레벨스위치에 관한 것이다.
