    • A tire pressure indicator for coupling with a valve stem of a tire. The tire pressure indicator provides a first visual indication in the event that the tire pressure is below a first threshold limit and a second visual indication if the tire pressure is above a second threshold limit. The pressure indicator includes a dome shaped indicator and a dome shaped cover that is mounted over the indicator. The cover includes a plurality wedge shaped transparent viewing windows extending from near the top of the dome. The transparent viewing windows are separated by opaque portions. The indicator has a plurality of alternating wedge shaped areas of first and second colors extending from near the top of the dome to the lower peripheral edge of the indicator. The rotation of the indicator is related to the tire pressure. In one orientation of the indicator that occurs when the tire pressure is below a first predetermined limit, the first color is visible through the transparent viewing windows of the outer dome. In a second orientation of the inner dome that exists when the tire pressure is above a second predetermined limit, the second color is visible through the viewing windows of the outer dome.
    • 一种用于与轮胎的阀杆联接的轮胎压力指示器。 轮胎压力指示器在轮胎压力低于第一阈值极限的情况下提供第一视觉指示,以及如果轮胎压力高于第二阈值极限则提供第二视觉指示。 压力指示器包括一个圆顶形指示器和一个安装在指示器上的圆顶盖。 盖子包括从靠近顶部顶部延伸的多个楔形透明观察窗。 透明观察窗由不透明部分分开。 指示器具有多个从顶部的顶部附近延伸到指示器的下周边边缘的第一和第二颜色的交替楔形区域。 指示器的旋转与轮胎压力有关。 在轮胎压力低于第一预定极限时发生的指示器的一个方向上,通过外圆顶的透明观察窗可见第一颜色。 在轮胎压力高于第二预定极限时存在的内部圆顶的第二方向上,通过外圆顶的观察窗可见第二颜色。

    • An tire pressure indicator operative to provide a first visual indication if the tire pressure within a tire to which the indicator is coupled is below a first predetermined pressure and a second different visual indication if the tire pressure is above a second predetermined pressure. The indicator includes first and second magnetic members rotatably mounted within a housing that includes a transparent portion. The first magnetic member rotates in response to air pressure applied to a diaphragm that is mechanically coupled to the first magnetic member. The second magnetic member includes portions having first and second visual characteristics that are viewable through a transparent portion. The second magnetic member is cooperative with the first magnetic member to rotatably orient the second magnetic member such that the first or second visual characteristic is visible through the transparent portion.
    • 轮胎压力指示器,其操作以提供第一视觉指示,如果所述指示器所联接的轮胎内的轮胎压力低于第一预定压力,并且如果所述轮胎压力高于第二预定压力则表示第二不同的视觉指示。 指示器包括可旋转地安装在包括透明部分的壳体内的第一和第二磁性构件。 第一磁性构件响应于施加到机械地联接到第一磁性构件的隔膜的空气压力而旋转。 第二磁性构件包括具有通过透明部分可视的第一和第二视觉特性的部分。 第二磁性构件与第一磁性构件协作以使第二磁性构件可旋转地定向,使得通过透明部分可见第一或第二视觉特性。
