摘要： PROBLEM TO BE SOLVED: To shorten the whole length of a shaft and miniaturize a pump itself by providing the uniaxial eccentric screw pump with flexible parts of coil spring structure and by constituting a flexible shaft. SOLUTION: A uniaxial eccentric screw pimp incorporates a flexible shaft 7, the flexible shaft 7 has deflection parts 9 of coil spring constitution in both sides of the shaft 8, and couplings 10 are provided in the respective deflection parts 9. A drive shaft of a drive part 5 is connected to the coupling of one of the deflection parts 9 of the flexible shaft 7, and a rotor 3 is connected to the coupling of the other deflection part ρ so as to be used. As a result, since the deflection caused by the eccentricity of the drive shaft of the drive part and the rotor 3 can be absorbed by the spring, the deflection angle of the flexible shaft 7 can be set large to shorten the whole length of the shaft part 8, thereby shortening the pump itself.

摘要： PROBLEM TO BE SOLVED: To largely set tolerane of components of a driving unit which has a rotational body and a casing housing it. SOLUTION: A rotational body 16 is rotatably arranged inside a casing 10 and is in contact with a housing hole 11 of the casing 10. A rotary shaft 17 is attached to the rotational body 16, which shaft is rotated around a rotational center O2 eccentrically dislocated from a reference axis O0 of a housing chamber by specified length E. An eccentric bearing 25 is rotatably arranged in the casing 10 around a rotational center O1 eccentrically dislocated from both the rotational center O2 and the reference axis O0 by the specified lengths. The eccentric bearing 25 is rotated together with the rotation of the rotary shaft 17, so that the rotational body 16 is brought into contact with a sliding contact part 11a with specified stress.

摘要： PROBLEM TO BE SOLVED: To suppress residue of powder with a simple structure by arranging a guide in a funnel-like space so as to secure a flow passage for the powder in respect to an inner wall surface of a pump casing part which determines the funnel-like space, and forming an air inlet on a portion other than the part determining the funnel-like space. SOLUTION: A guide 22 for powder is arranged in a funnel-like space 16 of a powder transferring pump 1. The guide 22 has an outer surface shape substantially similar to an inner wall surface of a pump casing 10 which determines the funnel-like space 16, and is arranged for securing a flow passage 23 for powder in respect to the inner wall surface of the pump casing which determines time funnel-like space 16. An air inlet 19 is formed on a portion of the pump casing, other than the part which determines the funnel-like space 16. The guide 22 occupies a large part of the funnel-like space 16, for preventing residue of powder which is fed to the funnel-like space 16 from a gap between a rotor 9 and a stator 8, on a lower side of the space. Application of braking function of air to the powder is thus prevented.

摘要： PURPOSE: To pressure highly viscous material with certainty even when a recessed piston is inclined and locked by providing a guide piston set independently on and linearly to the recessed piston which is fitted to a cylinder of a cartridge. CONSTITUTION: A guide piston set 200 is arranged on a recessed piston 102. The guide piston set 200 is composed of a guide piston 201, an O ring 202 arranged on an outer periphery of the guide piston 201, a center hole for pulling out the guide piston 201, and a valve part arranged in the center hole. A screw 205 is threaded on the center hole for pulling out the guide piston 201. A valve 203 arranged inside the center hole is pressurized against a valve seat by means of a spring 204. The spring 204 has strength so as not to be opened by pneumatic pressure of 2 to 3 atms. Stable discharging is performed without inclining the recessed piston 102 nor causing air leakage.

摘要： PURPOSE:To facilitate the operation of a pump when at least two uniaxial eccentric screw pumps are combined to cope with the increase in the discharge pressure, and reduce the energy loss by mutually controlling the operation of two or more pumps. CONSTITUTION:Two uniaxial eccentric screw pumps 2, 3 to be driven by variable speed motors 6, 7 are connected to each other through a piping 4, a pressure switch 82 to instruct the operation and the stopping of a pump 3 based on the pressure in the piping 4 is provided in the vicinity of a suction port 31a of the high pressure side pump 3, and a pressure sensor 81 to set the upper limit pressure and the lower limit pressure is interposed in the piping 4. The low pressure side pump 2 is rotated at a constant prescribed speed while the speed of the high pressure side pump 3 is controlled through the pressure sensor 81 so that the pressure in the piping 4 may be within the range between the upper limit pressure and the lower limit pressure.

摘要： PURPOSE:To provide a screw pump which can prevent the fluid flowing in a passage from leaking to the rear part of the passage through the gap between a screw and the inner wall of the passage and the screw from becoming unrotatable because of the collision of screw blades against the fluid solid-likely stuck to the inner wall of the passage. CONSTITUTION:A shaft bar 10 for a screw is formed so as to be flexible, and a screw blade 20 is also formed of a flexible member, and a screw 30 is formed of a flexible number. The outer diameter of the screw 30 is formed smaller than the inner diameter of a passage 40 to provided a gap 42 between the circumference of the screw 30 and the inner wall of the passage 40. When the screw 30 is rotated in the passage 40, while a plurality of portions in the top section of the screw blades 20 are sliding on the inner wall of the passage 40, the screw 30 is continuously rotated while waving and dancing in the passage 40.
