摘要： An air duct mounted to a fan having an end board includes a top board which defines an opening, through which the fan is extended. Two opposite blocking members extend up from the top board at opposite first sides of the opening. Two opposite limiting members extend up from the top board at opposite second sides of the opening. Each blocking member includes a tab to block a top of the end board of the fan. Each limiting member includes a projection to abut a bottom of the end board of the fan.

摘要： Disclosed herein is an electric fan. The electric fan includes a casing, a rotary unit and a cover. The casing has a frame shape such that a first opening is formed in a central portion of the casing. An inlet hole and an outlet hole are respectively formed in inner and outer peripheral surfaces of the frame. A space is defined in the casing. The rotary unit includes an impeller installed in the space, and a drive unit. The rotary unit is configured such that when the impeller is rotated by the drive unit, external air is drawn into the space through the inlet hole and then discharged out of the space through an outlet hole. The cover is installed on a front part of the casing in a direct contact manner. The cover defines a second opening communicating with the first opening so that air supplied from the outlet hole is discharged out of the second opening.

摘要： A nozzle for a fan assembly includes an air inlet, an air outlet, an interior passage for conveying air from the air inlet to the air outlet, an annular inner wall, and an outer wall extending about the inner wall. The interior passage is located between the inner wall and the outer wall. The inner wall at least partially defines a bore through which air from outside the nozzle is drawn by air emitted from the air outlet. A flow control port is located downstream from the air outlet. A flow control chamber is provided for conveying air to the flow control port. A control mechanism selectively inhibits a flow of air through the flow control port to deflect an air flow emitted from the air outlet.

摘要： In the present invention, an outer peripheral surface (14S) of a second bell mouth (14) is located in a lower side (V) in a vertical direction of a lower end (16) of a first bell mouth (12). That is, the lower end (16) of the first bell mouth (12) is located opposite to a direction (D2) in which the second bell mouth (14) is opened, compared to an upper end (18) of the second bell mouth (14) in the lower side (V) in the vertical direction of the lower end. In other words, the upper end (18) of the second bell mouth (14) in the lower side (V) in the vertical direction of the lower end (16) of the first bell mouth (12) is located closer to the direction (D2) in which the second bell mouth (14) is opened, than the lower end (16).

摘要： A casing assembly for a compressor where traditional inlet and discharge nozzles are replaced with a mounting surface created from weld filler material applied to the outside surface of a casing. The weld filler material, and a portion of the outside surface of the casing, are cooperatively milled to create a generally planar or flat surface having a casing conduit centrally-disposed therein. A flange may then be coupled to the flat surface for the inlet or discharge of a process gas.

摘要： To provide a vacuum pump in which possibilities of decreased exhaust performance and gas leakage at the time of breakage of a rotor are lessened, in the case where a rotating part closes the inside opening portion of an exhaust outlet portion to decrease the height dimension of the vacuum pump, and further a connector lead wire is installed easily.
An inside opening edge portion of a gas discharge passage for combining the downstream space of the rotor with the exhaust outlet portion is caused to take a shape such that the opening edge portion has no blind portion when a gas exhaust passage forming member is viewed from at least either of an upper side or an oblique upper side, or from at least either of an lower side or an oblique lower side. Furthermore, the inner corner portion of this opening edge portion is formed into a rounded shape to reduce stress concentration. Also, a base is provided with a groove for combining a lead wire installing hole with a hole in the central part, and further the corners of these parts are formed into a rounded shape.
