摘要:
A gas exchange valve arrangement for a supercharged internal combustion engine, which arrangement comprises a gas exchange valve (1) having a valve head (2) and a valve stem (3) connected to the valve head (2), the arrangement further comprising a valve spring (4) being arranged around the valve stem (3) for creating a force for closing the valve (1), a chamber (5) being arranged around the valve stem (3), and thrust means (6, 19) being attached to the valve stem (3) and being movable in the direction of the longitudinal axis of the valve stem (3) together with the gas exchange valve (1). The arrangement comprises means (7, 14) for introducing pressurized charge from an air intake duct (10) of the engine air into the chamber (5) between the thrust means (6, 19) and the inner end of the chamber (5) for assisting in keeping the valve (1) closed. The invention also concerns a cylinder head (9).
摘要(中):
一种用于增压内燃机的气体交换阀装置,该装置包括具有连接到阀头(2)的阀头(2)和阀杆(3)的气体交换阀(1),该装置还包括 阀弹簧(4)围绕阀杆(3)布置以产生用于关闭阀(1)的力,围绕阀杆(3)布置的腔室(5),以及推力装置(6,19) 连接到阀杆(3)并且可以与气体交换阀(1)一起在阀杆(3)的纵向轴线方向上移动。 该装置包括用于将来自发动机空气的进气管道(10)的加压气体引入推进装置(6,19)和腔室(5)的内端之间的腔室(5)中的装置(7,14) 用于辅助保持阀(1)关闭。 本发明还涉及一种气缸盖(9)。
