摘要： An impeller include a substantially cylindrical impeller body with an internal flow path connecting between an inlet opening through a first end surface and an outlet opening through a circumferential surface; and a balance weight embedded in the impeller body. The balance weight has a vertically-elongated shape in which its height in a cylindrical axis direction is larger than its thickness in a radial direction. The vertically-elongated balance weight is embedded in a circumferential section of the cylindrical impeller body.

摘要： An impeller includes an impeller body in which an internal flow path and a recessed section are formed; a lid covering an opening of the recessed section; and a balance weight arranged between the impeller body and the lid. The lid is attached and fixed to the impeller body through an engagement section. Holding sections for the balance weight are formed in a back-side surface of the lid. When attaching and fixing the lid to the impeller body, the balance weight is sandwiched between the holding section of the lid and the impeller body to be fixed.

摘要： An impeller includes an impeller body which rotates about a rotation axis, and a vane which is provided at the impeller body. The impeller body receives force asymmetric with respect to the rotation axis in driving and rotation in a fluid in a manner that radially inward fluid force, which is generated due to arrangement of the vane, acts on a predetermined point in a peripheral direction. In the impeller body, a filled space filled, in a fluid, with the fluid is formed.

摘要： A centrifugal pump impeller 11 includes an impeller body in which an inner channel 35 is formed, and a single centrifugal vane 37 provided in the impeller body so as to have a leading edge at an outlet and a trailing edge at a predetermined point of an outer periphery of the impeller body. The centrifugal vane 37 is designed so that the area of an outer channel 36, which is defined by the centrifugal vane 37, in an angle range of 270° in a peripheral direction from the trailing edge of the centrifugal vane 37 to the total area of the impeller body surrounded by the outer periphery of the impeller body is less than 0.3.

摘要： An air inlet 16 is formed in a rear surface side vertical wall section 10b, or a single surface of an apparatus main body 10, and an air stream path that extends from the air inlet 16 of the rear surface side vertical wall section 10b to air outlets 14a and 14b formed upwardly aslant in an inclined surface section 13 that is also the single surface provided in the opposite direction. In this air stream path are arranged an air-cooling absorber 17, an air-cooling condenser 19 and fans 15a and 15b provided with their fan axes arranged upwardly aslant in correspondence with the air outlets 14a and 14b. With this arrangement, the air-cooling absorption type refrigerating apparatus is made to have an integrated air intake space and a reduced installation area, and an air stream path extending from the air inlet to the air outlets is made to have a reduced draft loss to allow the flow velocity distribution of the air stream of the heat exchange section to be uniformed.
