To check somewhat the inovemeiit of the core i, a ddsh-pot, k,is used. The piston l of the dash-pot is provided witli a valve,V, which opens by a downward pressure and allows an easydownward movement of the iron core i, but closes and checksthe movement of the core when it is pulled up by the actionof the solenoid. To balance the opposing forces, the weight of the movingparts, and the pull exerted by the solenoid upon the iron core,the wei^-hts w w may lie used. The adjustment is such tliatwlien the solenoid is traversed l)y the normal current it is juststrong enough to l)alance the downward i)ull of tlie parts. The electrical circnit-coiuiections are substantially X\\v sanu as.
