Title:
ELECTRICALLY CONTROLLABLE DELAYING DEVICE
Document Type and Number:
Japanese Patent JPS583560
Kind Code:
A
Abstract:
PURPOSE:To enable to operate stably for a long period of time without necessity of fine adjustment of frictional force and tension of a spring in a delaying device by providing an electromagnetic holder for attracting and holding a piston or piston rod against the tension of the spring on one end surface of a cylinder. CONSTITUTION:A stator yoke 2 made of a ferromagnetic material is provided on the bottom of a cylinder 1 having a choke groove 1 on the inner wall made of nonmagnetic material. The yoke 2 is formed in double cylindrical shape having a bottom, and an exciting coil 3 is mounted thereon. A piston having a holder 4 made of a nonmagnetic material and a movable yoke 5 is slidably contained in the cylinder 1. The yoke 5 is secured to the holder 4, and is upwardly urged by a spring 6. Further, one end of a flexible film 7 made of rubber or the like is pressed via a piston rod 8 on the holder 4.
