Abstract: A vehicle linear motor includes: a tubular casing; a pair of armatures placed and fixed in the casing; a mover formed in a flat plate shape and placed to face the pair of armatures and to be movable in the casing; and a support member configured to slidably support the mover such that the mover moves in a longitudinal direction of the mover. The mover formed in the flat plate shape includes a plurality of magnets that are arranged at intervals in the longitudinal direction. Each of the pair of armatures has a magnetic pole that is arranged to move the mover relative to the armatures in the longitudinal direction. The casing is mounted on a vehicle such that the longitudinal direction is a horizontal direction, and the mover and the armatures are placed to face each other in the horizontal direction.

Abstract: An electromagnetic valve, which is provided between an intake port of a compressor body and a pneumatic line at an intermediate position of an intake pipe, is opened/closed by a control unit. Communication between the intake port of the compressor body and the pneumatic line is permitted when the valve is open, and is blocked when the valve is closed. In a start-up control of the compressor body, the electromagnetic valve is opened, permitting communication of the pneumatic line in the plant with the intake port of the compressor body for power supply to an electric motor to drive an orbiting scroll. Rattling of the orbiting scroll by an amount equal to the axial gap (play) is suppressed before starting a compression operation.

Abstract: An electromagnetic valve at an intake side is provided between an intake port of a compressor body and a pneumatic line at an intermediate position of an intake pipe. The electromagnetic valve is opened/closed by the control unit. When the valve is opened, a communication of the intake port of the compressor body and the pneumatic line is allowed. When the valve is closed, the communication between the intake port and the pneumatic line is blocked. Under a start-up control of the compressor body, the electromagnetic valve at the intake side is opened to communicate the pneumatic line in the plant with the intake port of the compressor body for power supply to an electric motor to drive an orbiting scroll. The rattle of the orbiting scroll by an amount equal to the axial gap (play) is suppressed before starting a compression operation.
