Description
図1(a)に示したように、カム10が吸気弁4を開方向(矢印A方向)へ駆動した場合、カム10が中間ステム6を介して吸気弁4を矢印A方向へ押し下げる。この場合、吸気弁4の矢印A方向への移動により第一のばね5が圧縮されるので、第一のばね5に反発力(図1の矢印C方向の力)が発生する。この第一のばね5の反発力は、第一のばね5のバネ定数K1に吸気弁4の矢印A方向への変位Xを掛けたK1Xになる。この場合、中間ステム6と吸気弁4とが当接した状態で一体的に開弁方向へ変位するため、第二のばね8は、その両端が相対変位することなく中間ステム6及び吸気弁4とともに開弁方向へ変位する。すなわち、カム10によって吸気弁4が開弁されるときには、第二のばね8は伸縮しないことになる。従って、吸気弁4は第一のばね5の反発力(図1の矢印C方向の力)によってのみ矢印B方向へ駆動される。
2 燃焼室
3a 弁座
4 吸気弁
5 第一のばね(ばね手段)
6 中間ステム(作用部)
7 駆動機構
8 第二のばね(離間抑制手段、抑制ばね手段)
Claims (1)
- 燃焼室を開閉する弁と、前記弁を弁座に向かって押し付ける力を発生するばね手段と、前記弁と接触及び離間が可能な作用部を介して前記弁を開方向へ駆動する駆動機構と、前記作用部と前記弁との離間を抑制する離間抑制手段と、を備え、
前記離間抑制手段として、前記作用部から前記弁にかけて架設された抑制ばね手段を備えていることを特徴とする内燃機関の動弁機構。
