Abstract

PURPOSE:To contrive to miniaturize and to enhance instantaneous responsibility of the oil dash-pot type electromagnet by a method wherein a trip pin to transmit action of the dash-pot block is constituted of a magnetic mateial to reduce magnetic rsistance of the gap between a stator core and a pole head. CONSTITUTION:The oil dash-pot block OP is constituted in a closely sealed structure consisted of a cylinder 24 consisted of a nonmagnetic material and having a bottom, a braking oil 25 enclosed in the cylinder thereof, a plunger 26 cnsisted of a magnetic material and is accomodted as an up-and-down motion freely, a reversion spring 27 fitted up elastically in the cylinder 24 and to activate the plunnger 26 downward, and the pole head 28 consisted of a magnetic mterial to seal closely the opening part of the cylinder 24. The magnetic stator core 29 is fixed at the nearly center of the upper side curved piece 19b of a yoke 19, the lower end face thereof is made to face with the upper end face of the head 28, a sliding hole 30 is formed at the nearly center of the core 29, and the trip pin 31 penetrates thereof slidably.
