Definition of "dashpot timer" |
a fluid time-on timer that can be used in definite time DC motor acceleration starters and controllers. The dashpot timer functions where a magnetic field forces a piston to move within a cylinder when the coil is energized. Themovement of the piston is limited by fluid passing through an orifice on the piston. The amount of fluid passing through the orifice is controlled by a throttle value, which in turn determines the amount of time delay. After the fluid pressure equalizes across the piston, movement stops and contacts change state. The fluid can either be air (pneumatic dashpot) or oil (hydraulic dashpot). When the timer is deenergized, a check valve allows the pressure to equalize across the piston rapidly, thereby causing the contacts to change state “immediately.” |
