Abstract: A vent apparatus is described for providing filtered air intake and rollover protection for a fuel tank. The apparatus may include a housing configured to be coupled with the fuel tank, the housing including at least one air intake port and at least one air exhaust port. The apparatus may include an air intake filter disposed within the housing and configured to receive and filter air from the at least one air intake port. The apparatus may include a rollover protection valve disposed adjacent to the housing and configured to be located inside the fuel tank when the housing is coupled with the fuel tank, the rollover protection valve coupled with the at least one air exhaust port. The rollover protection valve may include a chamber and a plug configured to impede the flow of fuel from the fuel tank into the at least one air exhaust port.

Abstract: A float valve apparatus is provided for regulating the level of fluid within a tank. The apparatus may include a housing having one or more inlet ports and an outlet port that are each fluidly connected via a channel disposed within the housing. A float disposed within the housing may move relative to the housing between a first position and a second position when a fluid level in the tank reaches a preset level. A shaft may extend from the float into a chamber, and as the float moves from the first position to the second position, fluid may enter a chamber and bias the float further upward. In some examples, the shaft is further configured to increasingly obstruct the flow of fluid in the channel as the float moves from the first position to the second position.

Abstract translation: 提供一种用于调节罐内流体水平的浮阀装置。 该装置可以包括具有一个或多个入口端口和出口端口的壳体，每个入口端口和出口端口通过设置在壳体内的通道流体连接。 当罐中的液位达到预设水平时，设置在壳体内的浮子可以在第一位置和第二位置之间相对于壳体移动。 轴可以从浮子延伸到室中，并且当浮子从第一位置移动到第二位置时，流体可以进入室并进一步向上偏置浮子。 在一些示例中，轴进一步构造成随着浮子从第一位置移动到第二位置而逐渐阻碍通道中的流体流动。
