20110033279 | ROTOR DRIVE MECHANISM AND PUMP APPARATUS - To provide a rotor drive mechanism which realizes that a rotor rotating at high speed can be used by reducing the amount of heat and vibrations generated when the rotor is rotated at high speed and lowering a contact pressure between an outer surface of the rotor and an inner surface of a stator inner hole or preventing the outer surface of the rotor and the inner surface of the stator inner hole from contacting each other. | 02-10-2011 |
20100129252 | PUMPING-OUT APPARATUS AND METHOD FOR PUMPING OUT STORED FLUID - To simplify a pumping-out operation, prevent a follow plate from being contaminated by leakage of a fluid from a contact portion between the follow plate and a container, and reduce the size of a pumping-out apparatus. | 05-27-2010 |
20100092317 | Uniaxial Eccentric Screw Pump - An object of the present invention is to provide a uniaxial eccentric screw pump capable of transferring and filling a fluid while realizing high flow rate accuracy, low pulsation, and long life. | 04-15-2010 |
20100040498 | ROTOR DRIVE MECHANISM, ECCENTRIC SHAFT SEALING STRUCTURE, AND PUMP APPARATUS - To transfer and fill a fluid with high flow rate accuracy and a long operating life, and realize small size, light weight, low cost, and energy saving. | 02-18-2010 |
20090252630 | Single-Shaft Eccentric Screw Pump - A double/triple-thread single-shaft eccentric screw pump is provided. The rotor of the pump overhangs little in comparison with the flange type connecting structure. The whole length of the pump is short, and the pump casing of the pump is short and small in diameter, so that the pump is small in size and light in weight. One end of a flexible rod is tapered and has a tapped hole formed at its axis. One end of the rotor has a tapered bore formed at its axis, into which the tapered end of the flexible rod is fitted. The rotor has a through bore formed at its axis, through which a tension bolt extends from the other end of the rotor. The tension bolt has a front threaded end, which is screwed into and fastened to the tapped hole of the flexible rod. | 10-08-2009 |
