    摘要： An illustrative example embodiment of a compressor assembly includes a compressor housing having a suction inlet and a discharge outlet. A flow restricting valve allows unrestricted fluid flow in a first direction into the housing through the suction inlet and out of the discharge outlet during a first operating condition. The flow restricting valve allows a restricted fluid flow in a second, opposite direction into the housing through the discharge outlet in a second operating condition.

    摘要： An axial blower includes: a housing including a wind tunnel; an impeller that is disposed in the wind tunnel and includes a plurality of blades; and a motor that includes a rotation shaft and is secured to the housing, the impeller being secured to the rotation shaft. When an angle between a chord of the blade at a cross-sectional surface of the blade cut by a virtual cylindrical surface centering the rotation shaft, and a surface perpendicular to the rotation shaft is defined as a mounting angle, the blade includes an intermediate part between an inside diameter side part and an outside diameter side part of the blade, and this intermediate part has a mounting angle equal to or larger than a mounting angle of the inside diameter side part, and larger than a mounting angle of the outside diameter side part.

    摘要： The volute is cast integrally with the gearbox base to allow closer radial tolerances to be used to improve efficiency. In the preferred embodiment, compressors for multi-stage compression are assembled with intercoolers and the integral volute is cast together with the impeller housing and the lower gearbox housing and the associated intercooler. Efficiency increases of 2% or more are achievable. In multistage applications, efficiency gains in the early stages are compounded in each subsequent stage. Speed changes that change center distance between bull gear and pinion are accommodated by an offset opening in the inlet and diffuser that can line up with the impeller shaft as well as an offset opening in the fluid seal despite a pinion gear change, by reorientation and remounting of those parts.

    摘要： A folding desk fan includes a fan shell, a supporting shell and damping members. The fan shell is provided with an air supply component, and elongated openings are arranged on two sides of the fan shell. Two sides of the supporting shell extend upwards to form connecting arms. Free ends of the two connecting arms are oppositely provided with two rotating shafts. The rotating shafts are inserted along the openings. The rotating shafts are able to rotate in the openings and slide in lengthwise directions of the openings to cause the supporting shell to move between a storage position and an open position. And the damping members are connected to the rotating shafts and are located between the rotating shafts and the fan shell. And the damping members are configured to hinder relative rotation between the rotating shafts and the fan shell.

    摘要： Provided is a vacuum blower, when used as a vacuum for sucking work, capable of increasing air flow with a larger volume of air sucked from a suction port and increasing the initial velocity (sucking rate) of sucked objects near the suction port, and when used as a blower for blowing work, capable of delivering rectilinearly directed wind from the blowing port and quickly switching between sucking work and blowing work. By sliding an inner pipe disposed inside a pipe relative to the pipe, opposite end portions of the inner pipe come into close contact with opposite end portions (turn portions) of a nozzle facing the opposite end portions of the inner pipe, such that one ejection port is closed and the other ejection port is opened to allow pressurized wind generated by a blower fan to be ejected along the inside of the inner pipe to switch between sucking state and blowing state.
