Patent number: 9322579Abstract: A magneto-caloric effect type heat pump apparatus provides a thermo-magnetic cycle apparatus. A magnetic field modulating device has a rotary permanent magnet. By rotating the permanent magnet, magnetic field applied to a magneto-caloric element is modulated alternatively in a magnetized state and a demagnetized state. A magnetized period, when the magnetic field is applied, is shorter than a demagnetized period, when the magnetic field is removed. Thereby, it is possible to reduce weight of the magnetic field modulating device having the permanent magnet. The magneto-caloric element has a heat exchange portion which varies heat exchanging efficiency depending on flow directions of a heat transport medium. The heat exchanging efficiency in the magnetized period is higher than the heat exchanging efficiency in the demagnetized period. Therefore, it is possible to provide sufficient heat exchanging quantity even in a short magnetized period.Type: GrantFiled: April 9, 2014Date of Patent: April 26, 2016Assignee: DENSO CORPORATIONInventors: Tsuyoshi Morimoto, Naoki Watanabe, Shigeo Nomura, Takuya Fuse

Publication number: 20140311165Abstract: A vehicle air-conditioner has a magneto-caloric effect type heat pump apparatus (MHP apparatus). MHP apparatus has a magneto-caloric element (MCE element) which generates heat dissipation and heat absorption in response to strength change of an external magnetic field. The MCE element can demonstrate high performance when an element temperature is in a highly efficient temperature zone. A controller has an initial control part which adjusts the element temperature so that the element temperature approaches to the highly efficient temperature zone when the MHP apparatus is in an initial state in which the temperature is out of the highly efficient temperature zone. Thereby, starting of MHP apparatus is promoted. The initial control part may activate an auxiliary apparatus. The auxiliary apparatus heats or cools a part or all of the MCE elements.Type: ApplicationFiled: April 21, 2014Publication date: October 23, 2014Applicant: DENSO CORPORATIONInventors: Naoki Watanabe, Tsuyoshi Morimoto, Shigeo Nomura, Takuya Fuse

Patent number: 8347851Abstract: When a control valve allows communication through a fuel drain channel, fuel flows into an inner control chamber from an outer control chamber through a communication channel and flows out to a fuel tank. The fuel flow through the communication channel generates a differential pressure between inner control pressure and outer control pressure. Thus, an outer differential pressure immediately after an outer valve opening time can be set small, restraining an increase in the unburnt HC content of exhaust gas at low load, which could otherwise result from a high rising speed of an outer needle valve immediately after the outer valve opening time. An inner differential pressure immediately after an inner valve opening time can be set large, restraining an increase in the smoke content of exhaust gas, which could result from a low rising speed of an inner needle valve immediately after the inner valve opening time.Type: GrantFiled: September 8, 2008Date of Patent: January 8, 2013Assignee: Toyota Jidosha Kabushiki KaishaInventors: Fumihiro Okumura, Shigeo Nomura

Publication number: 20100170475Abstract: When a control valve 48 allows communication through a fuel drain channel C3, fuel flows into an inner control chamber R2i from an outer control chamber R2o through a communication channel 47 and flows out from the inner control chamber R2i to a fuel tank T. The flow of fuel through the communication channel 47 generates a differential pressure between inner control pressure Pci and outer control pressure Pco (Pco>Pci). Thus, an outer differential pressure immediately after an outer valve opening time can be set small, thereby restraining an increase in the unburnt HC content of exhaust gas at low load, which could otherwise result from a high rising speed of an outer needle valve 42 immediately after the outer valve opening time.Type: ApplicationFiled: September 8, 2008Publication date: July 8, 2010Inventors: Fumihiro Okumura, Shigeo Nomura

Publication number: 20100133361Abstract: A fuel injection valve (2) includes a first injection hole group (14), a second injection hole group (15), a control chamber (20), a first needle valve (12), and a second needle valve (13). The first needle valve (12) opens/closes an injection hole in the first injection hole group (14). The second needle valve (13) opens/closes an injection hole in the second injection hole group (15). Lifting of the first needle valve (12), and lifting of the second needle valve (13) are controlled by a pressure of fuel in the control chamber (20). An automatic valve (32) is further provided to change a flow rate at which the fuel flows into the control chamber (20), or a flow rate at which the fuel flows out from the control chamber (20), based on a common-rail pressure in a fuel supply source (1), when the needle valves (12, 13) are lifted. Thus, the fuel injection valve (2) injects fuel at the optimum fuel injection rate in various engine operating states.Type: ApplicationFiled: April 3, 2008Publication date: June 3, 2010Inventors: Yoshinori Futonagane, Yoshimasa Watanabe, Shigeo Nomura, Yoshiaki Nishijima
