Abstract: A rotary electric machine includes a rotor, a stator having coils wound to surround the rotor, a cylindrical ring member fixedly mounted on the stator by shrinkage fitting, and a frame disposed on the outside of the ring member with a gap created in between. The distance of the gap varies as a result of thermal expansion of the stator and the ring member. An outer surface of the ring member goes into contact with the frame when the stator and the ring member thermally expand, whereby the stator and the ring member are efficiently cooled.

Abstract: A variable delivery type fuel supply apparatus capable of suppressing variation of fuel pressure within a delivery pipe and hence variation of fuel quantity injected through fuel injection valves and simplifying a control method therefor. The apparatus includes an oil relief passage (6) provided between the suction port of a fuel pump (4) and a pressurizing chamber (4e) across a suction valve (4a) of the fuel pump (4), an electromagnetic valve (7) disposed in the oil relief passage (6) and opened for a predetermined time during a discharge stroke of the fuel pump (4) for thereby controlling a discharge quantity of the fuel pump (4), and a control unit (108) for controlling the timing at which the electromagnetic valve (7) is opened. The control unit (108) is so designed as to control open/close operations of the electromagnetic valve (7) such that a time point for starting electrical energization of the electromagnetic valve (7) is fixedly set at a predetermined time point relative to the suction/discharge stroke of the fuel pump (4) while allowing the time point for terminating the electrical energization to be variable, to thereby control the discharge quantity of the fuel pump (4).

Abstract: Provided is a fixing structure for fixing a wire connection plate including a busbar (9) having an annular shape, and a wire connection plate holder (10) for holding the busbar (9). The fixing structure includes a frame (5) having a cylindrical shape, for accommodating the wire connection plate therein, and a sheet metal member (12) for fixing the wire connection plate. One end of the sheet metal member (12) is fixed on a flange (4) of the frame (5), and another end of the sheet metal member (12) presses an end surface of the wire connection plate in an axial direction of the frame (5), to thereby fix the wire connection plate. The wire connection plate is fixed by elasticity of the sheet metal member (12), and hence the wire connection plate can be held even under application of impact load.
