    摘要： Disclosed is an inflation valve enabling a user to quickly inflate and deflate an inflatable object. The inflation valve can include an inflation chamber that is an adequate size to capture a breath of air blown by a user from a distance away from an outside opening of the inflation chamber. This allows surrounding air into the area of low pressure created by the moving air, thereby greatly increasing the amount of air entering the inflatable object. To prevent air from escaping the inflatable object, the inflation valve can include a non-invertible one-way valve and/or an invertible one-way valve. Each valve can prevent air from escaping the inflation chamber until adequate pressure is applied from the outside opening of the inflation chamber, for example, as a result of a user blowing air into the inflation chamber. The invertible one-way valve can be inverted to reverse the properties of the valve.

    摘要： A valve assembly (200; 400; 600) for a fuel injector that includes a sleeve member (220; 420; 620) having an interior chamber (222; 422; 622), a piston member (224; 424; 624) supported for movement within the interior chamber of the sleeve member and separating an upstream pressure side of the valve assembly from a downstream pressure side of the valve assembly, and a dynamic sealing device (230; 430; 630) mounted to one of the sleeve member and the piston member for sealingly isolating the upstream pressure side of the valve assembly from the downstream pressure side of the valve assembly. The dynamic sealing assembly includes a PTFE seal member (232; 432; 632) having a generally C-shaped cross-section defining an internal cavity (234; 434; 634) having an opening (236; 436; 636) about the outer periphery thereof the seal member, and a helical spring (238; 438; 638) disposed within the internal cavity of the seal member for providing a constant sealing force to the seal member. The dynamic sealing device is positioned in the valve assembly so that the opening of the internal cavity of the seal member faces away from the upstream pressure side of the valve assembly and towards the downstream pressure side of the valve assembly.

    摘要： A pressure control valve is provided, which protects a hydraulic system by feeding a high-pressure flow rate back to the side of a hydraulic tank when hydraulic pressure on a hydraulic pump side is increased over a predetermined pressure. The pressure control valve includes a sleeve having an inlet port receiving hydraulic fluid and a low-pressure path communicating with a hydraulic tank, a main poppet opening and closing the low-pressure path with respect to the inlet port, a main poppet spring elastically biasing the main poppet in an initial state by pressing the main poppet to maintain the low-pressure path closed with respect to the inlet port, a pilot poppet having an orifice flow path to control pressure in the pressure chamber while maintaining a sliding state against a valve seat when pressure that exceeds a predetermined pressure is generated in the pressure chamber to open an internal flow path of the valve seat, and a pilot poppet spring elastically biasing the pilot poppet in an initial state by pressing the pilot poppet to maintain the internal flow path of the valve seat closed.
