Patent number: 11261864Abstract: Scroll compressor includes a shaft rotatably supported to a casing; an eccentric bush having a recess part into which one end portion of the shaft is inserted, an eccentric part eccentric to the shaft, and a balance weight disposed at the opposite side of the eccentric part with respect to the recess part; an orbiting scroll for performing the orbiting motion in interlock with the eccentric part; and a fixed scroll for forming a compression chamber together with the orbiting scroll. The casing has an orbiting groove in which the eccentric bush performs the orbiting motion, a buffer member is interposed between the orbiting groove and the balance weight. Rotation clearance is formed between the recess part and the shaft. The buffer member is compressed between the balance weight and the orbiting groove before the recess part and the shaft contact each other by the rotation clearance.Type: GrantFiled: July 17, 2019Date of Patent: March 1, 2022Assignee: Hanon SystemsInventors: Chi Myeong Moon, Chang Eon Park, In Cheol Shin, Hyun Seong Ahn, Kweon Soo Lim

Patent number: 11225966Abstract: A scroll compressor includes a shaft being rotated by a drive source, an eccentric bush including a recess part into which the shaft is inserted and an eccentric part being eccentric to the shaft, an orbiting scroll configured to perform an orbiting motion in interlock with the eccentric part, a fixed scroll tooth-engaged with the orbiting scroll, and a buffer member configured to prevent an outer periphery of the shaft and an inner periphery of the recess part from coming in contact with each other, wherein the buffer member is formed to be able to perform a relative motion with respect to the shaft and the recess part. Accordingly, the scrolls are prevented from being damaged, an impact sound is prevented from being generated, and an increase of an inertial force and an unbalance force of a rotating body is suppressed.Type: GrantFiled: March 17, 2020Date of Patent: January 18, 2022Assignee: HANON SYSTEMSInventors: Chi Myeong Moon, Chang Eon Park, Hyun Seong Ahn

Patent number: 11136979Abstract: A scroll compressor that includes a rotating shaft, an eccentric bush having a recess, into which one end of the shaft is inserted, and an eccentric portion eccentric to the shaft, an orbiting scroll operatively connected to the eccentric portion for orbiting, a fixed scroll engaged with the orbiting scroll, and a buffer member interposed between the one end of the shaft and the recess. Therefore, it is possible to prevent damage to the scrolls due to liquid refrigerant compression during initial operation and to prevent an impact sound between the shaft and the eccentric bush due to the rotational clearance therebetween.Type: GrantFiled: August 27, 2019Date of Patent: October 5, 2021Assignee: HANON SYSTEMSInventors: Chi Myeong Moon, In Cheol Shin, Kweon Soo Lim, Chang Eon Park, Hyun Seong Ahn, Soo Cheol Jeong
