This paper discusses the effect of shape of discharge valve on the cut-off of fuel spray in such a system. Experiments showed that, with an injection pipe of large bore and a discharge valve of ordinary type, the pressure time curve after the cut-off assumes a steplike form, and also that with a discharge valve of the Bosch type, the pressure varies violently, whereas if the discharge valve is removed from the pump and replaced with a non-return valve at the nozzle, a sharp cut-off is obtained. The same result may be obtained with an injection pipe of proper size and a discharge valve of the Bosch type. In this case, however, a secondary discharge will take place with a slight rise of oil pressure. With an injection pipe of very small bore, the cut-off will not be affected at all by the shape of the discharge valve.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA4148267000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京帝國大學航空研究所"}]},"item_9_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Aeronautical Research Institute, Tokyo Imperial University"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00387631","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"中西, 不二夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"伊藤, 正治"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"北村, 菊男"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NAKANISHI, Fujio","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"ITO, Masaharu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KITAMURA, Kikuo","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-24"}],"displaytype":"detail","filename":"SA4148267.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA4148267.pdf","url":"https://jaxa.repo.nii.ac.jp/record/35504/files/SA4148267.pdf"},"version_id":"d8503251-d797-4143-bbb4-a1de0eeab6c5"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Effect of Shape of Discharge Valve on the Cut-off of Fuel Spray in Injection Systems with Open Nozzles.","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Effect of Shape of Discharge Valve on the Cut-off of Fuel Spray in Injection Systems with Open Nozzles.","subitem_title_language":"en"}]},"item_type_id":"9","owner":"1","path":["1890","1993"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"35504","relation_version_is_last":true,"title":["Effect of Shape of Discharge Valve on the Cut-off of Fuel Spray in Injection Systems with Open Nozzles."],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T23:18:15.298775+00:00"}
