摘要： A fan having reversible blades supported on a ring. The blades have means for holding the blades against rotation around thin central axis so that they can be selectively set to either blow cooling air forward away from the driver or rearward to add to the comfort of the driver. The resilient means urging the blades outward is made up of rubber cylinders that receive the hubs of the blades. One end of the cylinder rests on the fan while the thick end of the cylinder rests on the fan blades. The cylinder has a barrel shaped inside surface which it in giving the sleeved a generally uniform spring rate throughout its entire excursion.
摘要翻译：具有支撑在环上的可逆刀片的风扇。叶片具有用于保持叶片抵抗围绕薄的中心轴旋转的装置，使得它们可以被选择性地设置为将冷却空气向前吹离驾驶员或向后吹，以增加驾驶员的舒适感。向外推动叶片的弹性装置由接收叶片的轮毂的橡胶滚筒构成。气缸的一端靠在风扇上，而气缸的较厚端部位于风扇叶片上。气缸具有桶形内表面，其在整个偏移中给予套筒大体上均匀的弹簧刚度。

摘要： A cooling fan and hub support for a vehicle with reversible blades is disclosed. The fan has a hub support comprising an outer ring having inwardly extending projections and an inwardly directed flange. Each blade has a stem received in a hole in one of the projections. An inner retaining ring which has outwardly extending projections is supported concentric with the outer ring. A helical spring is received in each of the projections and extends into a blind hole in each stem and the inner end of the spring rests on a retaining ring. The outer ring has spaced holes for attaching it to an engine shaft. The retaining ring has convolutions which curve outwardly around each of the spaced holes and have an arcuate circumferential part that supports each inner end of a spring.
