  • Patent number: 11105423
    Abstract: A mechanical sealing device according to an embodiment of the present invention includes: a sealing ring (13) attached to a protrusion (11a) protruding from a housing (11); a mating ring (23) attached to an end portion of a rotary shaft (21); a welded bellows provided around the protrusion (11a) and located between the housing (11) and the sealing ring (13). The welded bellows (15) presses the sealing ring (13) in an axial direction to cause the sealing ring (13) to be in contact with the mating ring (23), thereby ensuring high pressure force, and in particular, uniform pressure force along its entire circumference, so as to achieve high liquid tightness, while maintaining the sizes in axial and radial directions small. Furthermore, the welded bellows (15) works as a sealing member of blocking a liquid leaked out through the O-ring (14), thereby achieving assured liquid tightness.

  • Patent number: 10910974
    Abstract: A feedback control switching unit of an inverter control unit selects, based on a magnitude relationship between a predetermined switching determination amount and at least one switching threshold, at least one of feedback control units to thereby execute switching among feedback control modes, such as a current feedback control mode and a torque feedback control mode, of the respective feedback control units for driving of the AC motor. A switching command generating unit generates a switching command for an inverter based on a manipulated variable calculated by the selected feedback control unit. When a torque response request determining unit determines that a required torque responsiveness is high, the feedback control switching unit reduces the number of executions of switching among the feedback control modes.
