摘要： A spool-out type booster brake valve device for industrial vehicles is configured to allow hydraulic working fluid to be supplied not only to a booster chamber but also to a master chamber thereby eliminating the need to use a separate brake fluid reservoir tank for supplementing brake fluid in the master chamber. The brake valve device is used in an industrial vehicle equipped with a fluid pump, a reservoir tank and a brake actuator. The brake valve device includes a valve body having an inlet port, a drain port, a brake port, a booster chamber communicatable with the pump via the inlet port and a master chamber communicatable with the brake actuator via the brake port. The master chamber is connected to the inlet port to receive working fluid from the pump. A valve spool is slidably fitted in the valve body through the booster chamber and the master chamber, the valve spool being shifted between an idle position and an operating position. The brake valve device also includes a booster sleeve and a master piston which are moved along with the valve spool in response to the shifting movement of the valve spool into the operating position, thereby reducing the volume of the master chamber so that the fluid in the master chamber can be introduced into the brake actuator via the brake port.
摘要翻译：用于工业车辆的排液式增压制动阀装置构造成允许液压工作流体不仅被供给到增压室，而且还供给主室，从而不需要使用单独的制动液储罐来补充制动液在主室。制动阀装置用于配备有流体泵，储存罐和制动致动器的工业车辆中。制动阀装置包括具有入口端口，排水口，制动口，通过入口与泵连通的增压室的阀体以及通过制动端口与制动器致动器通信的主室。主室连接到入口以从泵接收工作流体。阀芯通过增压室和主室可滑动地装配在阀体中，阀芯在空转位置和操作位置之间移动。制动阀装置还包括增压套管和主活塞，其响应于阀芯进入操作位置的移动运动而与阀芯一起移动，从而减小主室的体积，使得流体在主室可以通过制动口引入制动执行器。

摘要： Disclosed is anti-slip vinyl flooring that is capable of forming a concavo-convex portion having a thickness of more than a given value on a PVC surface layer of the vinyl flooring, thus effectively preventing slipping thereon and further ensuring a high degree of dimension stability. The anti-slip vinyl flooring according to the present invention is formed by sequentially laminating a PVC surface layer, a PVC base layer, and a backing layer, from the top thereof, wherein a concavo-convex portion having a thickness in the range of 70 μm to 160 μm is formed on the PVC surface layer.
