摘要： PROBLEM TO BE SOLVED: To simplify control for excitating to a solenoid when a magnet and the solenoid are moved relatively in the axial direction by controlling excitating/ non-excitating to the solenoid by means of a controller so that the magnet acts against a force received by a wheel side member from the outside. SOLUTION: When a solenoid 20 is excited via a driving circuit, a force suppressing relative movement between an upper case 8, to which a solenoid assembly 21 is fixed, and a piston rod 5, between a vehicle body and a cylinder 4, and between a lower arm is actuated by means of magnetic force of the excited solenoid 20 and magnets 18, 19. In addition, by means of a combination of the magnets 18, 19 and an inner circumference solenoid assembly 23 which is not excited, relative positions between the magnets 18, 19 and the inner circumference solenoid assembly 23, that is, inner circumference solenoids 22, to which the magnets 18, 19 face, in the inner circumference solenoid assembly 23 are detected, so that arrangement of another member such as a vehicle height sensor can be dispensed with.

摘要： PROBLEM TO BE SOLVED: To reduce vibration when an electric air compressor is stopped by stopping the compressor after reducing the pressure of an air pipe between a shut-off valve and the compressor by an atmosphere open valve with the shut-off valve closed when stopping raising of the vehicle height. SOLUTION: A controller 39 controls current supplied to an electric motor 38 based on the vehicle height measured by a vehicle height sensor 43. That is to say, when a measured value of the vehicle height corresponds to a set value, the operation of the electric motor 38 is stopped and a plurality of shut- off valves 34, 35 and an atmosphere open valve 41 are closed. When onboard load is increased making the vehicle height under the set value due to such reasons as the increased number of passengers, the atmosphere open valve 41 is opened and then the electric motor 38 is energized after the elapse of a predetermined time to drive an electric air compressor 13. Then, after a predetermined time has passed, the atmosphere open valve 41 is closed and each shut-off valve 34, 35 is opened. With this configuration, torque variation of the electric motor 38 are minimized reducing the vibration.

摘要： PURPOSE:To make slow the torque change in a motor and the rise of air pressure and decrease vibration of a motor by shutting a cut-off valve when adjustment is conducted so that the car height is raised, and starting a motor-driven air compressor after duration of such a condition for a certain period that an atmosphere releasing valve is opened. CONSTITUTION:When the on-board load is increased by the increment, etc., of the number of driver and passenger(s) to cause lowering of the car height. it is sensed by a car height sensor 43, and a control device 39 opens an atmosphere releasing valve 41. After elapse of a certain period of time, current is fed to a motor 38 to put a motor-driven air compressor 13 in operation, and also the valve 41 is blocked while cut-off valves 34, 35 are opened. At this time, the air pressure in a conduit 28 sinks in the period from opening of the valve 41 till start of the motor 38, and the load on the compressor 13 reduces, so that the torque change in the motor 38 becomes gradual, and the vibration decreases. High pressure air is supplied to the air chambers 24, 25 of shock absorbers 16, 17 in association with operation of the compressor 13, and the car height is raised.
