  • Publication number: 20240132040
    Abstract: The disclosure provides an anti-lock brake device including an oil pressure tank, a valve, and a movable component. The oil pressure tank has an accommodation space, an oil inlet channel, and an oil outlet channel connected to the accommodation space. The valve is slidably located in the oil inlet channel and for sealing or opening an oil inlet of the oil inlet channel. The movable component is located in the accommodation space and has a connecting channel corresponding to the oil inlet and an oil outlet of the oil outlet channel. When the movable component is slid to a depressurized position, the movable component is moved away from the valve for sealing the oil inlet, a first volume is produced between the connecting channel and the oil inlet, and a second volume, smaller than the first volume, is removed from between the connecting channel and the oil outlet.

  • Patent number: 9958245
    Abstract: A liquid disruptor device and a method of manufacturing the same are introduced. The liquid disruptor device comprises a front casing, a liquid seal film, a rear casing, a plane wave generator and a counter-impact cover. The plane wave generator generates a plane blast wave which compresses a liquid contained in the front casing and a liner to not only focus blast energy of the liquid but also allow the liquid to form a liquid knife current for destroying explosives. Hence, the liquid disruptor device displays higher efficiency per unit weight of explosives when detonation thereof occurs at multiple points. Further, a liquid disruptor device module inclusive of at least two liquid disruptor devices combined to assume a geometric shape is introduced.
