摘要： [Problem] To provide a motor having an insulator capable of reducing the occurrence of a phenomenon wherein because of operation of a motor the outer peripheral wall of the insulator falls inside toward a winding drum portion due to changes with the passage of time. [Solution] In a motor having a rotor and a stator, a conductive wire is wound around the stator over a substantially cylindrical stator core and insulators (20). The insulators (20) are disposed oppositely at both end faces of a stator core in the axial direction, and are in contact with the end faces of the annular yoke of the stator core. The insulators (20) include: an annular outer peripheral wall (21) having the conductive wire wound on the outer peripheral surface thereof; a plurality of winding drum portions (22) which projects radially inward from the outer peripheral wall (21) for the conductive wire to be wound therearound; and inside flange portions (23) rising in the axial direction from each inside end of the winding drum portions. The outer peripheral wall (21) has a flat portion wherein the inner peripheral surface of the outer peripheral wall (21) on the winding drum portions (22) side is orthogonal to the projecting direction of the winding drum portions (22). The outer peripheral surface of the outer peripheral wall (21) near the winding drum portions (22) has an arc-like shape. The closer to the circumferentially central side of the winding drum portion (22), the greater the thickness in the radial direction of the outer peripheral wall (21).

摘要： Provided is a molded motor which arranges a conduction member on an outer wall of the molded motor while electrically connecting an output-side bracket with a counter-output-side bracket, at which time the conduction member is prevented from breaking or coming off. A metal conduction plate (60) for electrically connecting the output-side bracket (51) with the counter-output-side bracket (52) comprises: a first contact part (61) that is formed on one side of the conduction plate and comes into contact with a side surface of a counter-output-side bearing housing (520) in a state in which the first contact part is curved in a direction away from the outer wall (20); a second contact part (62) that is formed on the other side of the conduction plate and comes into contact with the inner side of the output-side bracket (51) press-fitted to the outer wall (20); and a conduction band (63) for linking the first contact part (61) with the second contact part (62). A retaining means is formed on the conduction plate (60) and the outer wall (20), said retaining means for retaining the state in which the first contact part (61) is in contact with the side surface of the counter-output-side bearing housing (520).

摘要： A CPU 110 compares the extracted outside air temperature with a first low pressure saturation temperature. When the outside air temperature is lower than the first low pressure saturation temperature, the CPU 110 switches a first three-way valve 22 and a second three-way valve 23 so that a second outdoor heat exchanger 25 is used as a condenser and that a first outdoor heat exchanger 24 is not used. When the outside air temperature is higher than a second low pressure saturation temperature which is the first low pressure saturation temperature to which a predetermined temperature is added, the CPU 110 switches the first three-way valve 22 and the second three-way valve 23 so that the first outdoor heat exchanger 24 is used as a condenser and that the second outdoor heat exchanger 25 is not used.

摘要： According to one embodiment, a rotary compressor sucks in refrigerant gas from the low pressure side of a refrigeration cycle and discharges compressed refrigerant gas to the high pressure side. The rotary compressor includes a first compressing unit (12S) and a second compressing unit (12T) arranged one on top of another with a partition board (140) therebetween. The partition board (140) is provided with a vertical hole (141) and a horizontal hole (143). After the front end (144a) of an injection copper tube (144) to inject a refrigerant liquid is loose fit in the horizontal hole (143), an injection liner (145) having an outer diameter larger than the inner diameter of the injection copper tube (144) is inserted into the injection copper tube (144) from the back end (144b) and is pressed up to the front end (144a) to increase the diameter of the front end (144a) of the injection copper tube (144) such that the injection copper tube (144) is tight fit in the horizontal hole (143).

摘要： A rotary compressor (1), used e.g. in an. air conditioner, includes a compressing unit (12) having an end plate (1603, 160T) that closes an end portion of an annular cylinder (1213, 121T). The end plate includes a groove portion (1633, 163T) accommodating a discharge valve portion (2003, 200T, 2013, 201T) having a reed valve type discharge valve (2003, 200T) and a discharge-valve limiter (201S, 201T). The discharge valve portion is attached to the groove portion with a rivet (203S, 203T). The groove portion has a rivet-side enlarged diameter portion (163Sa, 163Ta) formed into a semicircular step shape, and a diameter of the rivet-side enlarged diameter portion other than a bottom side thereof is larger than a diameter of the bottom side. This prevents a punch P that swages the rivet from interfering with the groove portion when attaching the discharge valve portion to the groove portion with the rivet.
