Abstract

"ESTRUTURA PARA PASSAGEM DE FLUXO DE AR DE REFRIGERAçãO PARA UM CABEçOTE DE CILINDRO". Objetivo A presente invenção refere-se a uma estrutura possibilitando uma intensificação adicional de efeito de resfriamento de ar, em uma estrutura para passagem de fluxo de ar de resfriamento para um cabeçote de cilindro (7, 40, 50, 70) em um motor de combustão interna (4; 60) do tipo refrigerado a ar incluindo uma câmara de combustão (11) em uma porção inferior, uma câmara de válvula (13) em uma porção superior, uma câmara de corrente de came (25) em uma porção lateral, uma porta de escape (22) em uma porção frontal de uma área entre a câmara de combustão (110 e a câmara de válvula (13), e uma porta de entrada (200 em uma porção traseira da área, sendo que uma porta de escape (22) está disposta em afastamento de uma câmara de corrente de came (25), a área entre a porta de escape (22) e a câmara de corrente de came (25) é feita para ser uma abertura frontal (30), uma porta de entrada (20) está disposta próximo à câmara de corrente de came (25), o lado oposto à câmara de corrente de came (25) da porta de entrada (20) é feita para ser uma abertura traseira (31), uma passagem de fluxo de ar de resfriamento na direção frontal-traseira (33) é fornecida que conecta a abertura frontal (30) e a abertura traseira (31) uma a outra, e uma passagem de fluxo de ar de resfriamento lateralmente (34) é fornecida a qual se ramifica lateralmente de uma porção aproximadamente central da passagem de ar de fluxo de ar de resfriamento em direção frontal-traseira (33) e é comunicada com uma abertura lateral (32) em uma superfície lateral de um cabeçote de cilindro (7)."REFRIGERATION AIRFLOW PASSAGE STRUCTURE FOR A CYLINDER HEAD". Objective The present invention relates to a structure enabling further intensification of the air cooling effect in a structure for passing cooling air flow to a cylinder head (7, 40, 50, 70) on a internal combustion (4; 60) air-cooled type including a combustion chamber (11) in a lower portion, a valve chamber (13) in an upper portion, a cam chain chamber (25) in a side portion , an exhaust port (22) in a front portion of an area between the combustion chamber (110 and the valve chamber (13)), and an inlet port (200 in a rear portion of the area, a exhaust (22) is disposed away from a cam chain chamber (25), the area between the exhaust port (22) and cam chain chamber (25) is made to be a front opening (30), an inlet port (20) is disposed next to the cam chain chamber (25), ol As opposed to the cam chain chamber (25) of the inlet port (20) is made to be a rear opening (31), a front-rear direction cooling air flow passage (33) is provided which connects the front opening (30) and rear opening (31) each other, and a laterally cooling air flow passageway (34) is provided which branches laterally from an approximately central portion of the airflow air passageway of front-rear cooling (33) and is communicated with a side opening (32) on a side surface of a cylinder head (7).
