Engine including intake air flow control assembly

包括进气流控制组件的发动机

Abstract

The invention relates to an engine including an intake air flow control assembly. The intake air flow control assembly includes an actuator, a valve shaft, a first valve member and a drive member. The actuator includes a drive shaft defining a first rotational axis. The valve shaft defines a second rotational axis. The first valve member is fixed for rotation with the valve shaft and adjusts air flow from an intake manifold to an engine intake port. The drive member is engaged with the drive shaft and the valve shaft. The drive member extends around an outer circumference of the drive shaft and around an outer circumference of the valve shaft. The drive shaft is rotatable in first and second rotational directions opposite one another to rotate the valve shaft via the drive member and rotationally displace the first valve member.
本发明涉及包括进气流控制组件的发动机。具体地,进气流控制组件可包括致动器,阀轴,第一阀构件和驱动构件。致动器包括限定第一旋转轴线的驱动轴。阀轴限定第二旋转轴线。第一阀构件固定用于与阀轴一起旋转并且调整从进气歧管到发动机进气口的气流。驱动构件与驱动轴和阀轴接合。驱动构件在驱动轴的外圆周的周围和阀轴的外圆周的周围延伸。驱动轴可在彼此相对的第一和第二旋转方向上旋转,从而经由驱动构件旋转阀轴以及旋转地移动第一阀构件。
