摘要： PURPOSE:To make a pressure accumulation part small-sized, by installing a turning-ON means for turning on a fluid pressure generation part when a brake instruction or loosening instruction is imparted, and allowing the fluid pressure in the pressure accumulation part to always hold the value close to the upper limit value. CONSTITUTION:An instruction signal 95 is outputted only in the case where a brake instruction 51 is imparted from a loosened state, and the instruction signal 95 is not outputted in the case of notch up. At the time t8, if the brake instruction 51 in one time is imparted, a fluid pressure generating part is turned on, and when an accumulation part signal 60 reaches an upper limit value 47, the fluid pressure generating part stops. If the brake operation in which the pressurized fluid in an accumulation part is consumed is carried out, the fluid pressure generation part is turned on immediately by the brake instruction 51, and the pressurized fluid in the accumulation part is replenished, and during the traveling of the vehicle, the accumulation part signal 60 always holds the value close to the upper limit value 47 of the set value. If the capacity in the set number of times is secured in the state close to the upper limit value 47, the capacity can be reduced in comparison with conventional, and the pressure accumulation part can be made small-sized.

摘要： PROBLEM TO BE SOLVED: To provide an operating device capable of certainly setting a spring in a predetermined power storing state and certainly detecting an operation of a safety brake. SOLUTION: A magnet 326 is disposed in a spring support body 304b of a wedge piston 304, a magnetic sensor 327 is disposed corresponding to the magnet, and power storing is detected based on displacements of the springs 305 and 306. A controller stops the power storing when the magnetic sensor 327 detects the magnet 326 and then goes into a non-detecting state, and establishes a detecting state by the reversion of locking a locking spring 314.

摘要： PROBLEM TO BE SOLVED: To detect accurately the brake reaction force of an actuation device. SOLUTION: Separately from a spring receptacle 303 to receive springs 305 and 306, a hold-down member 302 is provided to receive the spring receptacle 303, and guidance is made by a guide sleeve 301 in such a way that the hold- down member 302 is not inclined. Thereby the hold-down member 302 can press a resilient member 322 uniformly without inclination even if the spring receptacle 303 receiving the brake reaction force is inclined when safety brake is in actuation. A pressure sensor 323 detects the brake reaction force through the resilient member 322.

摘要： PROBLEM TO BE SOLVED: To make a pressure command signal coincide with a feed-back signal by correcting a drive command value according to a correction amount when the feed-back signal has a fear of being arranged under the condition wherein the feed-back signal does not coincide with the pressure command signal. SOLUTION: After a time t4, differential pressure exists between command pressure X corresponding to a pressure command signal and actual output pressure Y of a positional electromagnetic valve corresponding to a feed-back signal, and since the gradient of the output pressure Y gets gentle, the output pressure Y has a fear of being arranged as it is before it reaches the command pressure X. Then, in a division from the time t4 to a time t5, an additive amount B is added to a coil current value A to generate an output as a new coil current value A'. As a result, in the division from the time t4 to the time t5, the coil current value A' is increased gradually, i.e., piled up to be changed in the direction of parting from the current value. After the time t5, an effect of gradually increasing the coil current value A' appears so that the output pressure Y is gradually increased to approach the command pressure X.

摘要： PURPOSE:To detect abnormality, such that a check valve is made inoperative and insufficient opening, and to cope with this abnormality, in the case of an air source device. CONSTITUTION:An air source device has a main air reservoir 10 connected to an air compressor 6 through a check valve 8 and a pressure governing device 33 actuated on, when an air pressure of this main air reservoir is decreased to a pressure governing lower limit value, and actuated off when the air pressure is increased to a pressure governing upper limit value. In the air source device for controlling the air compressor driven based on on-off action of this pressure governing device, pressure detectors 31, 32 are provided in primary and secondary side passages of the check valve. A control part 30a for supervising a detection pressure of the pressure detector is connected to these pressure detectors, and in this control part, at the time of on-action of the pressure governing device, when the detection pressure of the pressure detector in the primary side of the check valve is increased higher than a preset value relating to the detection pressure of the pressure detector in the secondary side, or in addition when the detection pressure of the pressure detector in the primary side of the check valve is increased to the pressure governing upper limit value or more of the pressure governing device, driving of the air compressor is stopped.
