Abstract: A rotor for a motor is proposed, the rotor including: a magnet coupled to a shaft to surround an outer surface of the shaft and having opposite-polar magnetic portions circumferentially alternately arranged; a first fixed ring fixed to the shaft to surround an outer surface of the shaft, disposed in contact with an upper portion of the magnet, and having a first coupling portion at a lower end being in contact with a top of the magnet to prevent rotation relative to the magnet; and a second fixed ring fixed to the shaft to surround the outer surface of the shaft, disposed in contact with a lower portion of the magnet, and having a second coupling portion at an upper end being in contact with a bottom of the magnet to prevent rotation relative to the magnet.

Abstract: A centrifugal pump sealing structure is provided. In one aspect, one sealing member is provided at a position where leakage paths from a fluid compression space between a middle housing and a cover and an electric component installation space between the middle housing and a lower housing are connected. Then, the two spaces are sealed. The number of sealing members is reduced, so that the internal structure becomes simpler and the assembly of the sealing member becomes easier.

Abstract: A noise reduction type purge control solenoid valve includes a body including a connector that supplies electricity from the exterior; a cover coupled to the body having a fluid inlet and a fluid outlet, and formed with a fluid discharge passage connected to the fluid outlet therein; a solenoid component disposed in the body; and an armature disposed between the solenoid component and the fluid discharge passage and moving upward and downward by the solenoid component to open and close the fluid discharge passage. Further, a noise reduction member is mounted on the armature to reduce noise generated by contact between the fluid discharge passage and the armature. A noise reduction wall protrudes along a circumference of an upper surface of the noise reduction member.

Abstract: A fuel tank isolation valve for a vehicle includes a drive unit having a solenoid coil; a flow path unit having a vaporized fuel gas flow path; a valve assembly configured to open or close the flow path in the flow path unit by being operated by the drive unit, where the valve assembly includes: a first valve configured to open the flow path by being operated by a magnetic force generated by the coil; and a second valve configured to open the flow path while operating in conjunction with the first valve by being caught by the first valve when the first valve operates. The first valve and the second valve may operate in conjunction with each other by being mechanically caught, such that it is not necessary to provide a separate spring for operating the second valve.

Abstract: A purge control solenoid valve includes a gas access body including an evaporation gas inlet, an evaporation gas outlet, and a path that connects the evaporation gas inlet and the evaporation gas outlet; a valve operation body including an armature coupled to the gas access body and performing a reciprocating motion in a direction in which the armature is brought into close contact with or separated from the path by a core that generates a magnetic force; and an armature top member being in close contact with or separated from the path due to the reciprocating motion of the armature to open or close the path. The armature top member has a non-adhesion coating formed on a top surface of a body thereof, and the non-adhesion coating includes a binder, graphite, polytetrafluoroethylene, and a crosslinking agent.

Abstract: A purge control solenoid valve may include a middle housing in which an inlet flow path is formed and a middle flow path is formed on a center; a valve housing in which a driving module selectively communicating the inlet flow path and the middle flow path is installed; an upper cover coupled to the upper part of the middle housing and including a upper flow path selectively communicated with the middle flow path on the center; and a membrane provided on the upper cover and selectively communicating the middle flow path and the upper flow path.

Abstract: An ejector for vaporized fuel gas recirculation devices is provided. The ejector for vaporized fuel gas recirculation devices reduces the number of elements equipped in a vehicle and an ejector mounting angle is adjusted to be suitable for a layout environment of the vehicle. Accordingly, a mounting cavity of the vehicle is more efficiently designed. When an intake pressure of an intake manifold is reduced a base component is moved in a direction toward a first nozzle component, and a region of the base component except an aperture closes the first nozzle component.
