Title: Fluid pressure control valve
Inventor: MORI TAKESHI
IPC: B60T8/26
Filed: 1987-01-20
Abstract: PURPOSE:To release the rear wheel locking immediately by releasing the brake pedal when the rear wheels are being locked, by furnishing a fluid pressure piston mechanism to remove hysteresis to increase the rear fluid pressure on the way of depressurizing control beyond the split point, in addition to a fluid pressure control mechanism. CONSTITUTION:When the master fluid pressure Pm is made reduced on the way of increasing the rear fluid pressure by the returning movement of a piston 10 with step, the piston 10 with step draws in the liquid in the rear wheel cylinders by returning to the full stroke contact position as the master fluid pressure Pm decreases, even though the fluid pressure control mechanism is at a balanced condition closing the main flow route. As a result, the rear fluid pressure Pr is decreased to approach the split point, and even though the rear wheel locking is generated by the operation of the piston 10 with step, the rear wheel locking can be released immediately.

Abstract: PURPOSE:To obtain simple constitution by providing a safety circuit for detecting a trouble in a main circuit between a converter and an inverter and further providing an arithmetic device for fetching an output or the like from this safety circuit so as to apply a DC brake before action of an electromagnetic brake or to stop a PWM output. CONSTITUTION:When a safety circuit, except a safety circuit 21 of an inverter 4, is actuated during floor arrival action by running an elevator, a converter 2 is disconnected from power supplies R, S, T by deenergizing an electromagnetic switch 1. Now the microprocessor of a speed controller 15 keeps a DC current to continue its flow in an induction motor 5 until an electromagnetic brake 14 is actuated. Accordingly, DC braking acts on the motor 5 during this time to control acceleration of a cage 12. In the case such that the safety circuit 21 is actuated during the floor arrival action by running the elevator, the inverter 4 can not be continuously operated with the inverter 4 in trouble. That is, a PWM signal is stopped when an output of the circuit 21 is deenergized.
