Patent number: 11460049Abstract: An ejector includes a shaft coupled to a passage formation member defining a refrigerant passage inside a body, and the shaft is slidably supported by a support member fixed to the body. A drive mechanism moves the shaft in an axial direction to change a passage sectional area of the refrigerant passage. The passage formation member is provided with a vibration suppressive member including a first mobile end that applies a load to enlarge the refrigerant passage and a second mobile end that applies a load to narrow the refrigerant passage. Both the first mobile end and the second mobile end are disposed on a same side of a slide region of the support member in the axial direction.Type: GrantFiled: December 4, 2018Date of Patent: October 4, 2022Assignee: DENSO CORPORATIONInventors: Yoichiro Kawamoto, Kazunori Mizutori, Etsuhisa Yamada, Teruyuki Hotta, Eitaro Tanaka

Patent number: 10316865Abstract: An ejector has a nozzle, a body, a passage defining member and a drive portion. The body has a refrigerant suction port and a pressure increasing portion. A nozzle passage is defined between an inner surface of the nozzle and an outer surface of the passage defining member and has a minimum sectional area portion, a tapered portion, and an expansion portion. The minimum sectional area portion has a smallest passage sectional area. The tapered portion is located upstream of the minimum sectional area portion in a refrigerant flow direction and has a passage sectional area decreasing toward the minimum sectional area portion gradually. The expansion portion is located downstream of the minimum sectional area portion in the refrigerant flow direction and has a passage sectional area increasing gradually. The passage defining member has a groove that is recessed to increase the passage sectional area of the nozzle passage.Type: GrantFiled: March 2, 2016Date of Patent: June 11, 2019Assignee: DENSO CORPORATIONInventors: Yoshiyuki Yokoyama, Haruyuki Nishijima, Etsuhisa Yamada, Ryota Nakashima, Yoshiaki Takano, Kazunori Mizutori, Yorito Kohara, Hiroshi Shintani

Publication number: 20060236521Abstract: A pipe fixing structure and method are disclosed. In the pipe fixing structure, an ejector 1 on which a pipe 2 is to be fixed is subjected to a pressure which is exerted on the pipe 2 thereby to deform and fix the pipe 2. An enlarged portion 1a larger than the outer diameter of the pipe 2, through which the pipe 2 can be inserted in axial direction, is formed in the ejector 1. A thin portion 2a is formed on the inner peripheral portion of the pipe 2, and a first projection 6 is formed by plastic deformation of the thin portion 2a of pipe 2 under the pressure. The first projection 6 coincides with the enlarged diameter portion 1a so that the pipe is fixed on the ejector 1.Type: ApplicationFiled: April 12, 2006Publication date: October 26, 2006Applicant: Denso CorporationInventors: Masahiko Ikawa, Kazunori Mizutori
