摘要： The present invention relates to a ventilation insert or liner for headwear. The ventilation insert or liner is comprised of a top edge, bottom edge, a backside extending between the top edge and bottom edge, and a front side opposite the backside. The front side has at least one ventilation structure, such as a tube, extending between the top edge and the bottom edge that increases air flow (i.e., ventilation) from a cool area (e.g. below the brim of a hat) to the inside of the headwear. The ventilation insert or liner may comprise a plurality of ventilation structures. The plurality of ventilation structures may comprise a plurality of apertures to increase air flow. The back side may comprise a connection material to affix the vent insert or liner to the inside of the headwear. The ventilation insert or liner may alternatively be inserted into a sweatband found on the inside of most hats.

摘要： A check valve is provided for use with variable frequency drives and other applications. In one aspect, the check valve provides a poppet guided by a poppet guide in at least two locations to ensure stability between fully open and fully closed positions. In another aspect, the check valve includes a poppet guide adapted to receive a poppet in a stem receiving channel, the stem receiving channel including guide vanes engaging the poppet and auxilliary channels for self cleaning.

摘要： A speed controller valve system for regulating an opening speed and a closing speed of a pressure reducing valve includes a first inlet couplable to a main valve inlet of a pressure reducing valve. An outlet is couplable to a power chamber of the pressure reducing valve to control a flow of fluid between the outlet and the power chamber to control an opening and/or a closing of the pressure reducing valve. An interior chamber connects the first inlet and the outlet. The chamber receives a resilient member connected to a tapered valve poppet received in the first inlet and moveable in response to a flow of fluid at a pre-set pressure from the main valve inlet to the first inlet. The poppet is located in the chamber and the resilient member includes a resiliency to regulate an amount of movement of the poppet at the pre-set pressure to regulate a flow between the first inlet and the power chamber of the pressure reducing valve.
摘要翻译：用于调节减压阀的打开速度和关闭速度的速度控制阀系统包括可连接到减压阀的主阀入口的第一入口。出口可连接到减压阀的动力室，以控制出口和动力室之间的流体流动，以控制减压阀的打开和/或关闭。内部室连接第一入口和出口。腔室接收连接到容纳在第一入口中的锥形阀提升阀的弹性构件，并响应于从主阀入口到第一入口的预设压力的流体流动而运动。提升阀位于腔室中，并且弹性构件包括弹性以调节提升阀在预定压力下的运动量，以调节减压阀的第一入口和动力室之间的流动。
