Title: Method and device for deaerating liquid
Inventor: HIRANO TADASHI
IPC: B01D19/00
Filed: 1994-12-08
Abstract: PURPOSE: To simplify a device and to contrive cost reduction by floating and accumulating grown bubbles and discharging them through an exhaust pipe. CONSTITUTION: The inside of a vessel 3 is decompressed through an exhaust pipe 5 and a drainage pipe 7 by operating both an exhaust pump 9 and a circulation pump 12 and moderately regulating the valve travel of a throttle valve 10. As a result, liquid 2 to be treated is continuously sucked into the vessel 3 through a liquid supply pipe 6. Ultrasonic vibration radiated by an ultrasonic vibrator 4 driven by a power source device is transmitted to the liquid to be treated in the vessel 3. It is promoted that dissolved gas in the liquid is deposited as fine bubbles by its cavitation action. It is promoted that the fine bubbles are mutually combined and grown by agitating action thereof. Therefore, the bubbles grown without being redissolved in the liquid to be treated are floated on the liquid level and discharged by the exhaust pump 9.

Patent JP-H02180382-A (JP)
Title: One-way valve device
Inventor: IWAMOTO SHOICHI
IPC: F04B39/00
Filed: 1988-12-29
Abstract: PURPOSE:To make it possible to use the device in the title in substitute for the inlet valve or the exhaust valve of a pump or the like by providing a piston ring between a piston and a cylinder with a valve function to positively let operating fluid flow in one direction while restraining operating fluid from leaking in the reverse direction. CONSTITUTION:A sealing property is heightened as a ring 5 pressure-contact to the surface opposite to a peripheral groove 3a with sliding frictional resistance between the periphery of piston rings 4 and 5 and the inner wall of a cylinder 2 during the compression stroke. Additionally, as the pressure at the side of a discharge chamber 7 presses the piston rings 4 and 5 on the cylinder 2 through a tension ring 6, the sealing property between the piston rings 4 and 5 and the cylinder 2 is heightened. Accordingly, it is possible to prevent fluid from leaking from the discharge chamber 7 to the atmospheric space and it is possible to discharge fluid after a lead valve 10 is opened. On the other hand, the piston ring 4 makes pressure-contact to the surface opposite to the peripheral groove 3a with the frictional resistance between the piston rings 4 and 5 and the cylinder 2 at the time of expansion stroke, and the opposite side is separated and a clearance is generated. Accordingly, when the capacity of the discharge chamber 7 increases because of the movement of the cylinder 2 and the pressure decreases to a lower level than that in the space on the opposite side, operating fluid flows to the side of the discharge chamber 7 through grooves 6a and 4a from a clearance between the piston ring 5 and the peripheral groove 3a.
