Abstract

The present invention overcomes the disadvantages of prior art solenoids to develop adequate initial pulling force for a given coil size. The solenoid having a linear pull stroke includes a coil operated plunger (16) having a lost motion coupling (20, 28, 32, 38, 40) adapted to be connected with a load in order to allow the plunger (16) to retract a predefined distance during the initial part of the stroke thereby to develop a higher level of pulling force before substantial force is actually imparted to the load. The plunger (16) comprises an elongate body (18) having a piston-like link (28) slidably mounted in a cavity (20) at one end of the body (18) and adapted to be coupled with the load. A spring (36) trapped between the link (28) and the body (18) resets the link (28) relative to the body (18) before the pull stroke is completed.
