Latest Patents
Miwa holds a patent for a vibrator that features a hydraulic circuit connected to a hydraulic power unit. This invention includes an electromagnetic valve that regulates the actuation of a switch valve through a control signal. The design incorporates a plunger capable of bearing the load of an object to be tested, which has an oil chamber for pressurizing the plunger. This allows for upward and downward movement. The oil passage communicates with the oil chamber and the electromagnetic valve, enabling precise control over the vibration applying cylinder. This cylinder can vibrate the plunger at desired amplitudes and frequencies through hydraulic oil fed from the electromagnetic valve. Additionally, a lift means elevates the vibration applying cylinder to a predetermined height, while a controller outputs control signals to set the amplitude and frequency of the plunger.
