Title: Control valve
Inventor: SEKIKAWA KEIJI
IPC: F15B11/028
Filed: 1990-03-30
Abstract: PURPOSE:To simplify the constitution and realize a compact control valve by sliding pressure rise change-over spool and signal selector spool by signal of signal pressure port, controlling communication and non-communication of flow passage of pilot valve and tank, and selecting operation of low and high pressure set relief valves. CONSTITUTION:When no signal is input from any of signal pressure ports, 45, 47, 49, a low pressure set relief valve 9 communicates with a tank 59 and operates via flow passages, 57, 51, 53. When pressure of a hydraulic pipe 5 exceeds low set pressure of the valve 9, a pilot poppet 15 moves to the right, a valve body 21 moves to the right to open flow passages, and hydraulic oil in the hydraulic pipe 5 is discharged into a tank 11. In the same way, when A signal only is input from the port 45, the valve 9 does not operate and a high pressure set relief valve 7 operates. When signals are input simultaneously via the ports, 45, 47, the valve 9 operates. When signal is input from the port 49, the valve 9 operates. Thus, it is possible to simplify the constitution and make the control valve compact.

If a motor for driving a winding reel is stopped and magnetically energizing current is fed to the rotor part 206 of the clutch, when a disorderly wounded condition or a spirally wounded condition is presented, the armature part 207 is attracted and coupled to the rotor part 206, so that the torque is transmitted from the rotor part 206 to the armature part 207, and the loose drum 202 is rotated in the direction (a) since the torque from the drum shaft 203 is transmitted to the loose drum 202. Thus, a metal wire 1 wound onto the winding reel 3 is rewound, thereby the disorderly wound condition or the spirally wound condition may be eliminated.

Filed: 1987-04-09
Abstract: PURPOSE:To reduce impedance variation depending on the position of a tap by making the turn ratio of an outer tap winding and an inner tap winding nearly equal to the turn ratio of a line side high voltage winding and a neutral side high voltage winding.
