Patent number: 9109823Abstract: A vapor-liquid separating space is provided in a body. The body houses a fixed throttle-decompressing liquid-phase refrigerant, and an integration valve member selectively opening or closing a liquid-phase refrigerant passage and a vapor-phase refrigerant passage. The integration valve member is moved by a stepping motor connected to the integration valve member via a shaft. Accordingly, a cycle configuration of a heat pump cycle working as a gas injection cycle can be simplified.Type: GrantFiled: October 2, 2012Date of Patent: August 18, 2015Assignee: DENSO CORPORATIONInventors: Tetsuya Itou, Yukihiko Takeda, Teruyuki Hotta, Atsushi Inaba, Keiichi Yoshii, Shigeji Ohishi

Publication number: 20150013368Abstract: A temperature sensitive rod is communicated with a diaphragm that is displaceable in response to a pressure difference between an internal pressure of a sealed space, in which a temperature sensitive medium is sealed, and a pressure of a low pressure refrigerant outputted from an evaporator. A blind hole, which opens to the sealed space, is formed in an inside of the temperature sensitive rod. The temperature sensitive medium is a mixture gas of the refrigerant and an inert gas. A mixing ratio of the inert gas in the temperature sensitive medium corresponds to a ratio of an equivalent diameter of the blind hole relative to a depth of the blind hole in such a manner that a time constant of heat conduction from the temperature sensitive rod to the temperature sensitive medium is kept within a desired time constant range.Type: ApplicationFiled: December 5, 2012Publication date: January 15, 2015Applicant: DENSO CORPORATIONInventors: Hiroshi Oshitani, Teruyuki Hotta, Syuichi Mizuno, Ryu Fukushima, Shigeji Ohishi

Patent number: RE42908Abstract: The internal heat exchanger 7 is provided which exchanges heat between the refrigerant of low pressure and the refrigerant of high pressure, and the pre-load adjusting mechanism of the expansion valve 5 is abolished. Due to the above structure, the refrigerant flowing into the expansion valve 5 is cooled in the internal heat exchanger 7, and enthalpy of the refrigerant flowing into the evaporator 6 is reduced. On the contrary, the refrigerant sucked into the compressor 1 is heated. Accordingly, a difference in enthalpy between the refrigerant at the inlet and the refrigerant at the outlet of the evaporator 6 can be made large, and the heat absorbing capacity of the evaporator 6 can be enhanced, and further it becomes possible to give the degree of superheat to the refrigerant sucked into the compressor 1. Therefore, even if the pre-load adjusting mechanism is abolished, the vapor-compression-type refrigerating machine can be stably operated.Type: GrantFiled: November 21, 2005Date of Patent: November 15, 2011Assignee: Denso CorporationInventors: Shigeki Ito, Teruyuki Hotta, Yasushi Yamanaka
