Abstract:
(EN) A valve (33) has a recessed section (33c) in a contact section (33b) that is in contact with a valve seat (35), and when the valve is closed, a contact area between the valve (33) and the valve seat (35) is reduced compared with the case having no recessed section (33c).
(FR) La présente invention concerne une soupape (33) présentant une section évidée (33c) dans une section de contact (33b) qui est en contact avec un siège de soupape (35). Lorsque la soupape est fermée, une zone de contact entre la soupape (33) et le siège de soupape (35) est réduite par rapport au boîtier n'ayant pas de section évidée (33c).
(JA)  バルブ(33)は、バルブシート(35)との当接部(33b)に凹部(33c)を有しており、閉弁時にバルブ(33)とバルブシート(35)との当接面積は、凹部(33c)の無い場合と比べて減少する。
