Method for operating a magnetic valve for pneumatic brake cylinders
The method involves applying a pull-in current and connecting a free-running diode with a clocked permanent current to switch the valve on, changing to a holding current after reaching the pull-in current, resulting in a clocked permanent current signal that is slowly quenched with diodes to give a...

| description | The method involves applying a pull-in current and connecting a free-running diode with a clocked permanent current to switch the valve on, changing to a holding current after reaching the pull-in current, resulting in a clocked permanent current signal that is slowly quenched with diodes to give a d.c. coil current with low superimposed a.c.. The switch is opened to switch the valve for rapid quenching. The valve current is monitored. The method involves applying a pull-in current for a defined period and connecting a free-running diode (22) with a clocked permanent current to switch the valve (10) on, changing to a pulse width modulated, clocked holding current after reaching the pull-in current, resulting in a clocked permanent current signal, whereby the clocked permanent current is slowly quenched with diodes to give a d.c. coil current with a low superimposed a.c. current. The switch (18) is opened to switch the valve off to enable rapid quenching. The current to the magnetic valve is monitored by a monitoring device (26). AN Independent claim is also included for the following: a control system for operating magnetic valve for pneumatic brake cylinder. |
